The <a class="jump" href="SciCoding.html">coding style</a> used in Scintilla and SciTE is
worth following if you want to contribute code to Scintilla but is not compulsory.</p>
<h2>Introduction</h2>
<p>The Windows version of Scintilla is a Windows Control. As such, its primary programming
interface is through Windows messages. Early versions of Scintilla emulated much of the API
defined by the standard Windows Edit and RichEdit controls but those APIs are now deprecated in
favour of Scintilla's own, more consistent API. In addition to messages performing the actions
of a normal Edit control, Scintilla allows control of syntax styling, folding, markers, autocompletion
and call tips.</p>
<p>The GTK+ version also uses messages in a similar way to the Windows version. This is
different to normal GTK+ practice but made it easier to implement rapidly.</p>
<p>Scintilla does not properly support right-to-left languages like Arabic and Hebrew.
While text in these languages may appear correct, it is not possible to interact with this text
as is normal with other editing components.</p>
<p>This documentation describes the individual messages and notifications used by Scintilla. It
does not describe how to link them together to form a useful editor. For now, the best way to
work out how to develop using Scintilla is to see how SciTE uses it. SciTE exercises most of
Scintilla's facilities.</p>
<p>In the descriptions that follow, the messages are described as function calls with zero, one
or two arguments. These two arguments are the standard <code>wParam</code> and
<code>lParam</code> familiar to Windows programmers. These parameters are integers that
are large enough to hold pointers, and the return value is also an integer large enough to contain a
pointer.
Although the commands only use the
arguments described, because all messages have two arguments whether Scintilla uses them or
not, it is strongly recommended that any unused arguments are set to 0. This allows future
enhancement of messages without the risk of breaking existing code. Common argument types
are:</p>
<table cellpadding="1" cellspacing="2" border="0" summary="Common argument types">
<tbody valign="top">
<tr>
<th align="left">bool</th>
<td>Arguments expect the values 0 for <code>false</code> and 1 for
<code>true</code>.</td>
</tr>
<tr>
<th align="left">int</th>
<td>Arguments are 32-bit signed integers.</td>
</tr>
<tr>
<th align="left">const&nbsp;char&nbsp;*</th>
<td>Arguments point at text that is being passed to Scintilla but not modified. The text
may be zero terminated or another argument may specify the character count, the
description will make this clear.</td>
</tr>
<tr>
<th align="left">char *</th>
<td>Arguments point at text buffers that Scintilla will fill with text. In some cases,
another argument will tell Scintilla the buffer size. In others, you must make sure that
the buffer is big enough to hold the requested text. If a NULL pointer (0) is passed
then, for SCI_* calls, the length that should be allocated is returned.</td>
</tr>
<tr>
<th align="left" id="colour">colour</th>
<td>Colours are set using the RGB format (Red, Green, Blue). The intensity of each colour
is set in the range 0 to 255. If you have three such intensities, they are combined as:
red | (green &lt;&lt; 8) | (blue &lt;&lt; 16). If you set all intensities to 255, the
colour is white. If you set all intensities to 0, the colour is black. When you set a
colour, you are making a request. What you will get depends on the capabilities of the
system and the current screen mode.</td>
</tr>
<tr>
<th align="left" id="alpha">alpha</th>
<td>Translucency is set using an alpha value.
Alpha ranges from 0 (SC_ALPHA_TRANSPARENT) which is completely transparent to
255 (SC_ALPHA_OPAQUE) which is opaque. The value 256 (SC_ALPHA_NOALPHA)
is opaque and uses code that is not alpha-aware and may be faster. Not all platforms support
translucency and only some Scintilla features implement translucency.
The default alpha value for most features is SC_ALPHA_NOALPHA.</td>
</tr>
<tr>
<th align="left">&lt;unused&gt;</th>
<td>This is an unused argument. Setting it to 0 will ensure compatibility with future
enhancements.</td>
</tr>

<p>Messages with names of the form <code>SCI_SETxxxxx</code> often have a companion
<code>SCI_GETxxxxx</code>. To save tedious repetition, if the <code>SCI_GETxxxxx</code> message
returns the value set by the <code>SCI_SETxxxxx</code> message, the <code>SET</code> routine is
described and the <code>GET</code> routine is left to your imagination.</p>
<h2 id="TextRetrievalAndModification">Text retrieval and modification</h2>
<p>Each byte in a Scintilla document is followed by an associated byte of styling
information. The combination of a character byte and a style byte is called a cell. Style bytes
are interpreted an index into an array of styles.
Style bytes may be split into an index and a set of indicator bits
but this use is discouraged and indicators should now use
<a class="message" href ="#SCI_INDICATORFILLRANGE">SCI_INDICATORFILLRANGE</a>
and related calls.
The default split is with the index in the low 5 bits and 3 high bits as <a class="jump"
href="#Indicators">indicators</a>. This allows 32 fundamental styles, which is enough for most
languages, and three independent indicators so that, for example, syntax errors, deprecated
names and bad indentation could all be displayed at once. The number of bits used for styles
can be altered with <a class="message"
href="#SCI_SETSTYLEBITS"><code>SCI_SETSTYLEBITS</code></a> up to a maximum of 8 bits.
The remaining bits can be used for indicators.</p>
<p>In this document, 'character' normally refers to a byte even when multi-byte characters are used.
Lengths measure the numbers of bytes, not the amount of characters in those bytes.</p>
<p>Positions within the Scintilla document refer to a character or the gap before that
character. The first character in a document is 0, the second 1 and so on. If a document
contains <code>nLen</code> characters, the last character is numbered <code>nLen</code>-1.
The caret exists between character positions and can be located from before the first character (0)
to after the last character (<code>nLen</code>).</p>
<p>There are places where the caret can not go where two character bytes make up one character.
This occurs when a DBCS character from a language like Japanese is included in the document or
when line ends are marked with the CP/M standard of a carriage return followed by a line feed.
The <code>INVALID_POSITION</code> constant (-1) represents an invalid position within the
document.</p>
<p>All lines of text in Scintilla are the same height, and this height is calculated from the
largest font in any current style. This restriction is for performance; if lines differed in
height then calculations involving positioning of text would require the text to be styled
first.</p>

<p><b id="SCI_GETTEXT">SCI_GETTEXT(int length, char *text)</b><br />
This returns <code>length</code>-1 characters of text from the start of the document plus one
terminating 0 character. To collect all the text in a document, use <code>SCI_GETLENGTH</code>
to get the number of characters in the document (<code>nLen</code>), allocate a character
buffer of length <code>nLen+1</code> bytes, then call <code>SCI_GETTEXT(nLen+1, char
*text)</code>. If the text argument is 0 then the length that should be allocated to store the
entire document is returned.
If you then save the text, you should use <code>SCI_SETSAVEPOINT</code> to mark
the text as unmodified.</p>

This replaces all the text in the document with the zero terminated text string you pass
in.</p>
<p><b id="SCI_SETSAVEPOINT">SCI_SETSAVEPOINT</b><br />
This message tells Scintilla that the current state of the document is unmodified. This is
usually done when the file is saved or loaded, hence the name "save point". As Scintilla
performs undo and redo operations, it notifies the container that it has entered or left the
save point with <code><a class="message"
href="#SCN_SAVEPOINTREACHED">SCN_SAVEPOINTREACHED</a></code> and <code><a class="message"
href="#SCN_SAVEPOINTLEFT">SCN_SAVEPOINTLEFT</a></code> <a class="jump"
href="#Notifications">notification messages</a>, allowing the container to know if the file
should be considered dirty or not.</p>

<p><b id="SCI_GETLINE">SCI_GETLINE(int line, char *text)</b><br />
This fills the buffer defined by text with the contents of the nominated line (lines start at
0). The buffer is not terminated by a 0 character. It is up to you to make sure that the buffer
is long enough for the text, use <a class="message"
href="#SCI_LINELENGTH"><code>SCI_LINELENGTH(int line)</code></a>. The returned value is the
number of characters copied to the buffer. The returned text includes any end of line
characters. If you ask for a line number outside the range of lines in the document, 0
characters are copied. If the text argument is 0 then the length that should be allocated
to store the entire line is returned.</p>

The currently selected text between the <a class="jump" href="#SelectionAndInformation">anchor
and the current position</a> is replaced by the 0 terminated text string. If the anchor and
current position are the same, the text is inserted at the caret position. The caret is
positioned after the inserted text and the caret is scrolled into view.</p>
<p><b id="SCI_SETREADONLY">SCI_SETREADONLY(bool readOnly)</b><br />
<b id="SCI_GETREADONLY">SCI_GETREADONLY</b><br />
These messages set and get the read-only flag for the document. If you mark a document as read
only, attempts to modify the text cause the <a class="message"

<p><b id="SCI_GETTEXTRANGE">SCI_GETTEXTRANGE(&lt;unused&gt;, <a class="jump"

This collects the text between the positions <code>cpMin</code> and <code>cpMax</code> and
copies it to <code>lpstrText</code> (see <code>struct Sci_TextRange</code> in
<code>Scintilla.h</code>). If <code>cpMax</code> is -1, text is returned to the end of the
document. The text is 0 terminated, so you must supply a buffer that is at least 1 character

This collects styled text into a buffer using two bytes for each cell, with the character at
the lower address of each pair and the style byte at the upper address. Characters between the
positions <code>cpMin</code> and <code>cpMax</code> are copied to <code>lpstrText</code> (see
<code>struct Sci_TextRange</code> in <code>Scintilla.h</code>). Two 0 bytes are added to the end of
the text, so the buffer that <code>lpstrText</code> points at must be at least
<code>2*(cpMax-cpMin)+2</code> bytes long. No check is made for sensible values of
<code>cpMin</code> or <code>cpMax</code>. Positions outside the document return character codes
and style bytes of 0.</p>

They are outside the range 0..255 used for the styles bytes associated with document bytes.
These functions manage the use of extended styles to ensures that components cooperate in defining styles.
<code>SCI_RELEASEALLEXTENDEDSTYLES</code> releases any extended styles allocated by the container.
<code>SCI_ALLOCATEEXTENDEDSTYLES</code> allocates a range of style numbers after the byte style values and returns
the number of the first allocated style.

<p><b id="SCI_ENCODEDFROMUTF8">SCI_ENCODEDFROMUTF8(const char *utf8, char *encoded)</b><br />
<b id="SCI_SETLENGTHFORENCODE">SCI_SETLENGTHFORENCODE(int bytes)</b><br />
<code>SCI_ENCODEDFROMUTF8</code> converts a UTF-8 string into the document's
encoding which is useful for taking the results of a find dialog, for example, and receiving
a string of bytes that can be searched for in the document. Since the text can contain nul bytes,
the <code>SCI_SETLENGTHFORENCODE</code> method can be used to set the
length that will be converted. If set to -1, the length is determined by finding a nul byte.
The length of the converted string is returned.

There are methods to search for text and for regular expressions. The regular expression support
is limited and should only be used for simple cases and initial development. A different regular expression

Several of the search routines use flag options, which include a simple regular expression
search. Combine the flag options by adding them:</p>
<table border="0" summary="Search flags">
<tbody>
<tr>
<td><code>SCFIND_MATCHCASE</code></td>
<td>A match only occurs with text that matches the case of the search string.</td>
</tr>
<tr>
<td><code>SCFIND_WHOLEWORD</code></td>
<td>A match only occurs if the characters before and after are not word characters.</td>
</tr>
<tr>
<td><code>SCFIND_WORDSTART</code></td>
<td>A match only occurs if the character before is not a word character.</td>
</tr>
<tr>
<td><code>SCFIND_REGEXP</code></td>
<td>The search string should be interpreted as a regular expression.</td>
</tr>
<tr>
<td><code>SCFIND_POSIX</code></td>
<td>Treat regular expression in a more POSIX compatible manner
by interpreting bare ( and ) for tagged sections rather than \( and \).</td>

<p>You can
search backwards to find the previous occurrence of a search string by setting the end of the
search range before the start.</p>
<p>In a regular expression, special characters interpreted are:</p>
<table border="0" summary="Regular expression synopsis">
<tbody>
<tr>
<td><code>.</code></td>
<td>Matches any character</td>

<td><code>\)</code></td>
<td>This marks the end of a tagged region.</td>
</tr>
<tr>
<td><code>\n</code></td>
<td>Where <code>n</code> is 1 through 9 refers to the first through ninth tagged region
when replacing. For example, if the search string was <code>Fred\([1-9]\)XXX</code> and
the replace string was <code>Sam\1YYY</code>, when applied to <code>Fred2XXX</code> this
would generate <code>Sam2YYY</code>.
<code>\0</code> refers to all of the matching text.</td>
</tr>
<tr>
<td><code>\&lt;</code></td>
<td>This matches the start of a word using Scintilla's definitions of words.</td>
</tr>
<tr>
<td><code>\&gt;</code></td>
<td>This matches the end of a word using Scintilla's definition of words.</td>
</tr>
<tr>
<td><code>\x</code></td>
<td>This allows you to use a character x that would otherwise have a special meaning. For
example, \[ would be interpreted as [ and not as the start of a character set.</td>
</tr>
<tr>
<td><code>[...]</code></td>
<td>This indicates a set of characters, for example, [abc] means any of the characters a,
b or c. You can also use ranges, for example [a-z] for any lower case character.</td>
</tr>
<tr>
<td><code>[^...]</code></td>
<td>The complement of the characters in the set. For example, [^A-Za-z] means any
character except an alphabetic character.</td>
</tr>
<tr>
<td><code>^</code></td>
<td>This matches the start of a line (unless used inside a set, see above).</td>
</tr>
<tr>
<td><code>$</code></td>
<td>This matches the end of a line.</td>
</tr>
<tr>
<td><code>*</code></td>
<td>This matches 0 or more times. For example, <code>Sa*m</code> matches <code>Sm</code>,
<code>Sam</code>, <code>Saam</code>, <code>Saaam</code> and so on.</td>

This message searches for text in the document. It does not use or move the current selection.
The <a class="jump" href="#searchFlags"><code>searchFlags</code></a> argument controls the
search type, which includes regular expression searches.</p>
<p>The <code>Sci_TextToFind</code> structure is defined in <code>Scintilla.h</code>; set
<code>chrg.cpMin</code> and <code>chrg.cpMax</code> with the range of positions in the document
to search. You can search backwards by
setting <code>chrg.cpMax</code> less than <code>chrg.cpMin</code>.
Set the <code>lpstrText</code> member of <code>Sci_TextToFind</code> to point at a zero terminated
text string holding the search pattern. If your language makes the use of <code>Sci_TextToFind</code>
difficult, you should consider using <code>SCI_SEARCHINTARGET</code> instead.</p>
<p>The return value is -1 if the search fails or the position of the start of the found text if
it succeeds. The <code>chrgText.cpMin</code> and <code>chrgText.cpMax</code> members of

<p>Using <a class="message" href="#SCI_REPLACESEL"><code>SCI_REPLACESEL</code></a>,
modifications cause scrolling and other visible changes, which may take some time and cause

<code>SCI_REPLACETARGET</code> or <code>SCI_REPLACETARGETRE</code>.</p>
<p>Searching can be performed within the target range with <code>SCI_SEARCHINTARGET</code>,
which uses a counted string to allow searching for null characters. It returns the

<p><b id="SCI_REPLACETARGET">SCI_REPLACETARGET(int length, const char *text)</b><br />
If <code>length</code> is -1, <code>text</code> is a zero terminated string, otherwise
<code>length</code> sets the number of character to replace the target with.
After replacement, the target range refers to the replacement text.
The return value
is the length of the replacement string.<br />
Note that the recommended way to delete text in the document is to set the target to the text to be removed,
and to perform a replace target with an empty string.</p>
<p><b id="SCI_REPLACETARGETRE">SCI_REPLACETARGETRE(int length, const char *text)</b><br />
This replaces the target using regular expressions. If <code>length</code> is -1,

These commands perform the standard tasks of cutting and copying data to the clipboard,
pasting from the clipboard into the document, and clearing the document.
<code>SCI_CANPASTE</code> returns non-zero if the document isn't read-only and if the selection
doesn't contain protected text. If you need a "can copy" or "can cut", use
<code>SCI_GETSELECTIONEMPTY()</code>, which will be zero if there are any non-empty
selection ranges implying that a copy or cut to the clipboard should work.</p>
<p>GTK+ does not really support <code>SCI_CANPASTE</code> and always returns <code>TRUE</code>
unless the document is read-only.</p>
<p>On X, the clipboard is asynchronous and may require several messages between
the destination and source applications. Data from SCI_PASTE will not arrive in the
document immediately.</p>
<p><code>SCI_COPYALLOWLINE</code> works the same as SCI_COPY except that if the
selection is empty then the current line is copied. On Windows, an extra "MSDEVLineSelect" marker
is added to the clipboard which is then used in <code>SCI_PASTE</code> to paste
the whole line before the current line.</p>

<h2 id="UndoAndRedo">Undo and Redo</h2>
<p>Scintilla has multiple level undo and redo. It will continue to collect undoable actions
until memory runs out. Scintilla saves actions that change the document. Scintilla does not
save caret and selection movements, view scrolling and the like. Sequences of typing or
deleting are compressed into single transactions to make it easier to undo and redo at a sensible
level of detail. Sequences of actions can be combined into transactions that are undone as a unit.
These sequences occur between <code>SCI_BEGINUNDOACTION</code> and
<code>SCI_ENDUNDOACTION</code> messages. These transactions can be nested and only the top-level
sequences are undone as units.</p>

<code>false</code> (0) to stop collecting. If you stop collection, you should also use
<code>SCI_EMPTYUNDOBUFFER</code> to avoid the undo buffer being unsynchronized with the data in
the buffer.</p>
<p>You might wish to turn off saving undo information if you use the Scintilla to store text
generated by a program (a Log view) or in a display window where text is often deleted and
regenerated.</p>
<p><b id="SCI_BEGINUNDOACTION">SCI_BEGINUNDOACTION</b><br />
<b id="SCI_ENDUNDOACTION">SCI_ENDUNDOACTION</b><br />
Send these two messages to Scintilla to mark the beginning and end of a set of operations that
you want to undo all as one operation but that you have to generate as several operations.
Alternatively, you can use these to mark a set of operations that you do not want to have
combined with the preceding or following operations if they are undone.</p>
<p><b id="SCI_ADDUNDOACTION">SCI_ADDUNDOACTION(int token, int flags)</b><br />
The container can add its own actions into the undo stack by calling
<code>SCI_ADDUNDOACTION</code> and an <code>SCN_MODIFIED</code>
notification will be sent to the container with the
<a class="message" href="#SC_MOD_CONTAINER"><code>SC_MOD_CONTAINER</code></a>
flag when it is time to undo (<code>SC_PERFORMED_UNDO</code>) or
redo (<code>SC_PERFORMED_REDO</code>) the action. The token argument supplied is
returned in the <code>token</code> field of the notification.</p>
<p>For example, if the container wanted to allow undo and redo of a 'toggle bookmark' command then
it could call <code>SCI_ADDUNDOACTION(line, 0)</code> each time the command is performed.
Then when it receives a notification to undo or redo it toggles a bookmark on the line given by
the token field. If there are different types of commands or parameters that need to be stored into the undo
stack then the container should maintain a stack of its own for the document and use the current
position in that stack as the argument to <code>SCI_ADDUNDOACTION(line)</code>.
<code>SCI_ADDUNDOACTION</code> commands are not combined together
into a single undo transaction unless grouped with <code>SCI_BEGINUNDOACTION</code>
and <code>SCI_ENDUNDOACTION</code>.</p>
<p>The flags argument can be <code>UNDO_MAY_COALESCE</code> (1) if the container action may be
coalesced along with any insertion and deletion actions into a single compound action, otherwise 0.
Coalescing treats coalescible container actions as transparent so will still only group together insertions that
look like typing or deletions that look like multiple uses of the Backspace or Delete keys.
</p>
<h2 id="SelectionAndInformation">Selection and information</h2>
<p>Scintilla maintains a selection that stretches between two points, the anchor and the
current position. If the anchor and the current position are the same, there is no selected
text. Positions in the document range from 0 (before the first character), to the document size
(after the last character). If you use messages, there is nothing to stop you setting a
position that is in the middle of a CRLF pair, or in the middle of a 2 byte character. However,
keyboard commands will not move the caret into such positions.</p>

<p><b id="SCI_GETTEXTLENGTH">SCI_GETTEXTLENGTH</b><br />
<b id="SCI_GETLENGTH">SCI_GETLENGTH</b><br />
Both these messages return the length of the document in bytes.</p>
<p><b id="SCI_GETLINECOUNT">SCI_GETLINECOUNT</b><br />
This returns the number of lines in the document. An empty document contains 1 line. A
document holding only an end of line sequence has 2 lines.</p>
<p><b id="SCI_SETFIRSTVISIBLELINE">SCI_SETFIRSTVISIBLELINE(int lineDisplay)</b><br />
<b id="SCI_GETFIRSTVISIBLELINE">SCI_GETFIRSTVISIBLELINE</b><br />
These messages retrieve and set the line number of the first visible line in the Scintilla view. The first line
in the document is numbered 0. The value is a visible line rather than a document line.</p>
<p><b id="SCI_LINESONSCREEN">SCI_LINESONSCREEN</b><br />
This returns the number of complete lines visible on the screen. With a constant line height,
this is the vertical space available divided by the line separation. Unless you arrange to size
your window to an integral number of lines, there may be a partial line visible at the bottom
of the view.</p>
<p><b id="SCI_GETMODIFY">SCI_GETMODIFY</b><br />
This returns non-zero if the document is modified and 0 if it is unmodified. The modified
status of a document is determined by the undo position relative to the save point. The save
point is set by <a class="message" href="#SCI_SETSAVEPOINT"><code>SCI_SETSAVEPOINT</code></a>,
usually when you have saved data to a file.</p>
<p>If you need to be notified when the document becomes modified, Scintilla notifies the
container that it has entered or left the save point with the <a class="message"
href="#SCN_SAVEPOINTREACHED"><code>SCN_SAVEPOINTREACHED</code></a> and <a class="message"
href="#SCN_SAVEPOINTLEFT"><code>SCN_SAVEPOINTLEFT</code></a> <a class="jump"
href="#Notifications">notification messages</a>.</p>
<p><b id="SCI_SETSEL">SCI_SETSEL(int anchorPos, int currentPos)</b><br />
This message sets both the anchor and the current position. If <code>currentPos</code> is
negative, it means the end of the document. If <code>anchorPos</code> is negative, it means
remove any selection (i.e. set the anchor to the same position as <code>currentPos</code>). The
caret is scrolled into view after this operation.</p>
<p><b id="SCI_GOTOPOS">SCI_GOTOPOS(int pos)</b><br />
This removes any selection, sets the caret at <code>pos</code> and scrolls the view to make
the caret visible, if necessary. It is equivalent to
<code>SCI_SETSEL(pos, pos)</code>. The anchor position is set the same as the current
position.</p>
<p><b id="SCI_GOTOLINE">SCI_GOTOLINE(int line)</b><br />
This removes any selection and sets the caret at the start of line number <code>line</code>
and scrolls the view (if needed) to make it visible. The anchor position is set the same as the
current position. If <code>line</code> is outside the lines in the document (first line is 0),
the line set is the first or last.</p>
<p><b id="SCI_SETCURRENTPOS">SCI_SETCURRENTPOS(int pos)</b><br />
This sets the current position and creates a selection between the anchor and the current
position. The caret is not scrolled into view.</p>

<b id="SCI_GETSELECTIONEND">SCI_GETSELECTIONEND</b><br />
These return the start and end of the selection without regard to which end is the current
position and which is the anchor. <code>SCI_GETSELECTIONSTART</code> returns the smaller of the
current position or the anchor position. <code>SCI_GETSELECTIONEND</code> returns the larger of
the two values.</p>
<p><b id="SCI_SETEMPTYSELECTION">SCI_SETEMPTYSELECTION(int pos)</b><br />
This removes any selection and sets the caret at <code>pos</code>. The caret is not scrolled into view.</p>

This selects all the text in the document. The current position is not scrolled into view.</p>
<p><b id="SCI_LINEFROMPOSITION">SCI_LINEFROMPOSITION(int pos)</b><br />
This message returns the line that contains the position <code>pos</code> in the document. The
return value is 0 if <code>pos</code> &lt;= 0. The return value is the last line if
<code>pos</code> is beyond the end of the document.</p>
<p><b id="SCI_POSITIONFROMLINE">SCI_POSITIONFROMLINE(int line)</b><br />
This returns the document position that corresponds with the start of the line. If
<code>line</code> is negative, the position of the line holding the start of the selection is
returned. If <code>line</code> is greater than the lines in the document, the return value is
-1. If <code>line</code> is equal to the number of lines in the document (i.e. 1 line past the
last line), the return value is the end of the document.</p>
<p><b id="SCI_GETLINEENDPOSITION">SCI_GETLINEENDPOSITION(int line)</b><br />
This returns the position at the end of the line, before any line end characters. If <code>line</code>
is the last line in the document (which does not have any end of line characters), the result is the size of the
document. If <code>line</code> is negative or <code>line</code> &gt;= <a class="message"
href="#SCI_GETLINECOUNT"><code>SCI_GETLINECOUNT()</code></a>, the result is undefined.</p>
<p><b id="SCI_LINELENGTH">SCI_LINELENGTH(int line)</b><br />
This returns the length of the line, including any line end characters. If <code>line</code>
is negative or beyond the last line in the document, the result is 0. If you want the length of
the line not including any end of line characters, use <a class="message"
href="#SCI_GETLINEENDPOSITION"><code>SCI_GETLINEENDPOSITION(line)</code></a> - <a class="message"
href="#SCI_POSITIONFROMLINE"><code>SCI_POSITIONFROMLINE(line)</code></a>.</p>
<p><b id="SCI_GETSELTEXT">SCI_GETSELTEXT(&lt;unused&gt;, char *text)</b><br />
This copies the currently selected text and a terminating 0 byte to the <code>text</code>
buffer. The buffer size should be determined by calling with a NULL pointer for the <code>text</code> argument
<code>SCI_GETSELTEXT(0,0)</code>.
This allows for rectangular and discontiguous selections as well as simple selections.
See <a class="toc" href="#MultipleSelectionAndVirtualSpace">Multiple Selection</a> for information on
how multiple and rectangular selections and virtual space are copied.</p>

<p><b id="SCI_GETCURLINE">SCI_GETCURLINE(int textLen, char *text)</b><br />
This retrieves the text of the line containing the caret and returns the position within the
line of the caret. Pass in <code>char* text</code> pointing at a buffer large enough to hold
the text you wish to retrieve and a terminating 0 character.
Set <code>textLen</code> to the
length of the buffer which must be at least 1 to hold the terminating 0 character.
If the text argument is 0 then the length that should be allocated
to store the entire current line is returned.</p>

<p><b id="SCI_SETSELECTIONMODE">SCI_SETSELECTIONMODE(int mode)</b><br />
<b id="SCI_GETSELECTIONMODE">SCI_GETSELECTIONMODE</b><br />
The two functions set and get the selection mode, which can be
stream (<code>SC_SEL_STREAM</code>=0) or
rectangular (<code>SC_SEL_RECTANGLE</code>=1) or
by lines (<code>SC_SEL_LINES</code>=2)
or thin rectangular (<code>SC_SEL_THIN</code>=3).
When set in these modes, regular caret moves will extend or reduce the selection,
until the mode is cancelled by a call with same value or with <code>SCI_CANCEL</code>.
The get function returns the current mode even if the selection was made by mouse
or with regular extended moves.
<code>SC_SEL_THIN</code> is the mode after a rectangular selection has been typed into and ensures
that no characters are selected.</p>
<p><b id="SCI_GETLINESELSTARTPOSITION">SCI_GETLINESELSTARTPOSITION(int line)</b><br />
<b id="SCI_GETLINESELENDPOSITION">SCI_GETLINESELENDPOSITION(int line)</b><br />

<p><b id="SCI_MOVECARETINSIDEVIEW">SCI_MOVECARETINSIDEVIEW</b><br />
If the caret is off the top or bottom of the view, it is moved to the nearest line that is
visible to its current position. Any selection is lost.</p>

onlyWordCharacters)</b><br />
<b id="SCI_WORDSTARTPOSITION">SCI_WORDSTARTPOSITION(int position, bool

These messages return the start and end of words using the same definition of words as used
internally within Scintilla. You can set your own list of characters that count as words with
<a class="message" href="#SCI_SETWORDCHARS"><code>SCI_SETWORDCHARS</code></a>. The position
sets the start or the search, which is forwards when searching for the end and backwards when
searching for the start.</p>
<p>Set <code>onlyWordCharacters</code> to <code>true</code> (1) to stop searching at the first
non-word character in the search direction. If <code>onlyWordCharacters</code> is
<code>false</code> (0), the first character in the search direction sets the type of the search
as word or non-word and the search stops at the first non-matching character. Searches are also
terminated by the start or end of the document.</p>
<p>If "w" represents word characters and "." represents non-word characters and "|" represents
the position and <code>true</code> or <code>false</code> is the state of
<code>onlyWordCharacters</code>:</p>

<p><b id="SCI_POSITIONBEFORE">SCI_POSITIONBEFORE(int position)</b><br />
<b id="SCI_POSITIONAFTER">SCI_POSITIONAFTER(int position)</b><br />
These messages return the position before and after another position
in the document taking into account the current code page. The minimum
position returned is 0 and the maximum is the last position in the document.
If called with a position within a multi byte character will return the position
of the start/end of that character.</p>
<p><b id="SCI_COUNTCHARACTERS">SCI_COUNTCHARACTERS(int startPos, int endPos)</b><br />
Returns the number of whole characters between two positions..</p>
<p><b id="SCI_TEXTWIDTH">SCI_TEXTWIDTH(int styleNumber, const char *text)</b><br />
This returns the pixel width of a string drawn in the given <code>styleNumber</code> which can
be used, for example, to decide how wide to make the line number margin in order to display a
given number of numerals.</p>
<p><b id="SCI_TEXTHEIGHT">SCI_TEXTHEIGHT(int line)</b><br />
This returns the height in pixels of a particular line. Currently all lines are the same
height.</p>
<p><b id="SCI_GETCOLUMN">SCI_GETCOLUMN(int pos)</b><br />
This message returns the column number of a position <code>pos</code> within the document
taking the width of tabs into account. This returns the column number of the last tab on the
line before <code>pos</code>, plus the number of characters between the last tab and
<code>pos</code>. If there are no tab characters on the line, the return value is the number of
characters up to the position on the line. In both cases, double byte characters count as a
single character. This is probably only useful with monospaced fonts.</p>
<p><b id="SCI_FINDCOLUMN">SCI_FINDCOLUMN(int line, int column)</b><br />
This message returns the position of a <code>column</code> on a <code>line</code>
taking the width of tabs into account. It treats a multi-byte character as a single column.
Column numbers, like lines start at 0.</p>
<p><b id="SCI_POSITIONFROMPOINT">SCI_POSITIONFROMPOINT(int x, int y)</b><br />
<b id="SCI_POSITIONFROMPOINTCLOSE">SCI_POSITIONFROMPOINTCLOSE(int x, int y)</b><br />

<p><b id="SCI_CHARPOSITIONFROMPOINT">SCI_CHARPOSITIONFROMPOINT(int x, int y)</b><br />
<b id="SCI_CHARPOSITIONFROMPOINTCLOSE">SCI_CHARPOSITIONFROMPOINTCLOSE(int x, int y)</b><br />
<code>SCI_CHARPOSITIONFROMPOINT</code> finds the closest character to a point and
<code>SCI_CHARPOSITIONFROMPOINTCLOSE</code> is similar but returns -1 if the point is outside the
window or not close to any characters. This is similar to the previous methods but finds characters rather than
inter-character positions.</p>
<p><b id="SCI_POINTXFROMPOSITION">SCI_POINTXFROMPOSITION(&lt;unused&gt;, int pos)</b><br />
<b id="SCI_POINTYFROMPOSITION">SCI_POINTYFROMPOSITION(&lt;unused&gt;, int pos)</b><br />
These messages return the x and y display pixel location of text at position <code>pos</code>
in the document.</p>
<p><b id="SCI_HIDESELECTION">SCI_HIDESELECTION(bool hide)</b><br />
The normal state is to make the selection visible by drawing it as set by <a class="message"
href="#SCI_SETSELFORE"><code>SCI_SETSELFORE</code></a> and <a class="message"
href="#SCI_SETSELBACK"><code>SCI_SETSELBACK</code></a>. However, if you hide the selection, it
is drawn as normal text.</p>
<p><b id="SCI_CHOOSECARETX">SCI_CHOOSECARETX</b><br />
Scintilla remembers the x value of the last position horizontally moved to explicitly by the
user and this value is then used when moving vertically such as by using the up and down keys.
This message sets the current x position of the caret as the remembered value.</p>
<p><b id="SCI_MOVESELECTEDLINESUP">SCI_MOVESELECTEDLINESUP</b><br />
Move the selected lines up one line, shifting the line above after the selection.
The selection will be automatically extended to the beginning of the selection's first line and the end of the seletion's last line.
If nothing was selected, the line the cursor is currently at will be selected.</p>
<p><b id="SCI_MOVESELECTEDLINESDOWN">SCI_MOVESELECTEDLINESDOWN</b><br />
Move the selected lines down one line, shifting the line below before the selection.
The selection will be automatically extended to the beginning of the selection's first line and the end of the seletion's last line.
If nothing was selected, the line the cursor is currently at will be selected.</p>

<p>
There may be multiple selections active at one time.
More selections are made by holding down the Ctrl key while dragging with the mouse.
The most recent selection is the main selection and determines which part of the document is shown automatically.
Any selection apart from the main selection is called an additional selection.
The calls in the previous section operate on the main selection.
There is always at least one selection.
</p>
<p>
Rectangular selections are handled as multiple selections although the original rectangular range is remembered so that
subsequent operations may be handled differently for rectangular selections. For example, pasting a rectangular selection
places each piece in a vertical column.
</p>
<p>
Virtual space is space beyond the end of each line. The caret may be moved into virtual space but no real space will be
added to the document until there is some text typed or some other text insertion command is used.
</p>
<p>When discontiguous selections are copied to the clipboard, each selection is added to the clipboard text
in order with no delimiting characters.
For rectangular selections the document's line end is added after each line's text. Rectangular selections
are always copied from top line to bottom, not in the in order of selection.Virtual space is not copied.</p>

This will attempt to scroll the display by the number of columns and lines that you specify.
Positive line values increase the line number at the top of the screen (i.e. they move the text
upwards as far as the user is concerned), Negative line values do the reverse.</p>
<p>The column measure is the width of a space in the default style. Positive values increase
the column at the left edge of the view (i.e. they move the text leftwards as far as the user
is concerned). Negative values do the reverse.</p>

pixels near the vertical margins, and as a number of lines near the horizontal margins.
By keeping the caret away from the edges, it is seen within its context. This makes it

that any style extends above the baseline (its 'ascent'), added to the maximum that any style extends below the
baseline (its 'descent').
Space may be added to the maximum ascent (<code>SCI_SETEXTRAASCENT</code>) and the
maximum descent (<code>SCI_SETEXTRADESCENT</code>) to allow for more space between lines.
This may done to make the text easier to read or to accomodate underlines or highlights.

<h2 id="Cursor">Cursor</h2>
<p><b id="SCI_SETCURSOR">SCI_SETCURSOR(int curType)</b><br />
<b id="SCI_GETCURSOR">SCI_GETCURSOR</b><br />
The cursor is normally chosen in a context sensitive way, so it will be different over the
margin than when over the text. When performing a slow action, you may wish to change to a wait
cursor. You set the cursor type with <code>SCI_SETCURSOR</code>. The <code>curType</code>
argument can be:</p>
<table cellpadding="1" cellspacing="2" border="0" summary="Mouse cursors">
<tbody valign="top">
<tr>
<th align="left"><code>SC_CURSORNORMAL</code></th>
<td>-1</td>
<td>The normal cursor is displayed.</td>
</tr>
<tr>
<th align="left"><code>SC_CURSORWAIT</code></th>
<td>&nbsp;4</td>
<td>The wait cursor is displayed when the mouse is over or owned by the Scintilla
window.</td>
</tr>
</tbody>
</table>
<p>Cursor values 1 through 7 have defined cursors, but only <code>SC_CURSORWAIT</code> is
usefully controllable. Other values of <code>curType</code> cause a pointer to be displayed.
The <code>SCI_GETCURSOR</code> message returns the last cursor type you set, or
<code>SC_CURSORNORMAL</code> (-1) if you have not set a cursor type.</p>

<p><b id="SCI_SETMOUSEDOWNCAPTURES">SCI_SETMOUSEDOWNCAPTURES(bool captures)</b><br />
<b id="SCI_GETMOUSEDOWNCAPTURES">SCI_GETMOUSEDOWNCAPTURES</b><br />
When the mouse is pressed inside Scintilla, it is captured so future mouse movement events are
sent to Scintilla. This behavior may be turned off with
<code>SCI_SETMOUSEDOWNCAPTURES(0)</code>.</p>
<h2 id="LineEndings">Line endings</h2>
<p>Scintilla can handle the major line end conventions <span class="provisional">and, depending on settings and
the current lexer also support additional Unicode line ends</span>.</p>
<p>Scintilla can interpret any of the Macintosh (\r), Unix (\n) and Windows (\r\n)
line ends.
When the user presses the Enter key, one of these line
end strings is inserted into the buffer. The default is \r\n in Windows and \n in Unix, but
this can be changed with the <code>SCI_SETEOLMODE</code> message. You can also convert the
entire document to one of these line endings with <code>SCI_CONVERTEOLS</code>. Finally, you
can choose to display the line endings with <code>SCI_SETVIEWEOL</code>.</p>
<div class="provisional">
<p>For the UTF-8 encoding, three additional Unicode line ends,
Next Line (<code>NEL=U+0085</code>), Line Separator (<code>LS=U+2028</code>), and Paragraph Separator (<code>PS=U+2029</code>)
may optionally be interpreted when Unicode line ends is turned on and the current lexer also supports
Unicode line ends.</p>

Normally, the end of line characters are hidden, but <code>SCI_SETVIEWEOL</code> allows you to
display (or hide) them by setting <code>visible</code> <code>true</code> (or
<code>false</code>). The visible rendering of the end of line characters is similar to
<code>(CR)</code>, <code>(LF)</code>, or <code>(CR)(LF)</code>. <code>SCI_GETVIEWEOL</code>

</div>
<h2 id="Styling">Styling</h2>
<p>The styling messages allow you to assign styles to text. The standard Scintilla settings
divide the 8 style bits available for each character into 5 bits (0 to 4 = <a class="jump"
href="#StyleDefinition">styles 0 to 31</a>) that set a style and three bits (5 to 7) that
define <a class="jump" href="#Indicators">indicators</a>. You can change the balance between
styles and indicators with <a class="message"
href="#SCI_SETSTYLEBITS"><code>SCI_SETSTYLEBITS</code></a>. If your styling needs can be met by
one of the standard lexers, or if you can write your own, then a lexer is probably the easiest
way to style your document. If you choose to use the container to do the styling you can use
the <a class="message" href="#SCI_SETLEXER"><code>SCI_SETLEXER</code></a> command to select
<code>SCLEX_CONTAINER</code>, in which case the container is sent a <a class="message"
href="#SCN_STYLENEEDED"><code>SCN_STYLENEEDED</code></a> <a class="jump"
href="#Notifications">notification</a> each time text needs styling for display. As another
alternative, you might use idle time to style the document. Even if you use a lexer, you might
use the styling commands to mark errors detected by a compiler. The following commands can be
used.</p>
<code><a class="message" href="#SCI_GETENDSTYLED">SCI_GETENDSTYLED</a><br />
<a class="message" href="#SCI_STARTSTYLING">SCI_STARTSTYLING(int position, int mask)</a><br />
<a class="message" href="#SCI_SETSTYLING">SCI_SETSTYLING(int length, int style)</a><br />
<a class="message" href="#SCI_SETSTYLINGEX">SCI_SETSTYLINGEX(int length, const char

<a class="message" href="#SCI_GETMAXLINESTATE">SCI_GETMAXLINESTATE</a><br />
</code>
<p><b id="SCI_GETENDSTYLED">SCI_GETENDSTYLED</b><br />
Scintilla keeps a record of the last character that is likely to be styled correctly. This is
moved forwards when characters after it are styled and moved backwards if changes are made to
the text of the document before it. Before drawing text, this position is checked to see if any
styling is needed and, if so, a <code><a class="message"
href="#SCN_STYLENEEDED">SCN_STYLENEEDED</a></code> notification message is sent to the
container. The container can send <code>SCI_GETENDSTYLED</code> to work out where it needs to
start styling. Scintilla will always ask to style whole lines.</p>
<p><b id="SCI_STARTSTYLING">SCI_STARTSTYLING(int pos, int mask)</b><br />
This prepares for styling by setting the styling position <code>pos</code> to start at and a
<code>mask</code> indicating which bits of the style bytes can be set. The mask allows styling
to occur over several passes, with, for example, basic styling done on an initial pass to
ensure that the text of the code is seen quickly and correctly, and then a second slower pass,
detecting syntax errors and using indicators to show where these are. For example, with the
standard settings of 5 style bits and 3 indicator bits, you would use a <code>mask</code> value
of 31 (0x1f) if you were setting text styles and did not want to change the indicators. After
<code>SCI_STARTSTYLING</code>, send multiple <code>SCI_SETSTYLING</code> messages for each
lexical entity to style.</p>
<p><b id="SCI_SETSTYLING">SCI_SETSTYLING(int length, int style)</b><br />
This message sets the style of <code>length</code> characters starting at the styling position
and then increases the styling position by <code>length</code>, ready for the next call. If
<code>sCell</code> is the style byte, the operation is:<br />
<code>if ((sCell &amp; mask) != style) sCell = (sCell &amp; ~mask) | (style &amp;
mask);</code><br />
</p>
<p><b id="SCI_SETSTYLINGEX">SCI_SETSTYLINGEX(int length, const char *styles)</b><br />
As an alternative to <code>SCI_SETSTYLING</code>, which applies the same style to each byte,
you can use this message which specifies the styles for each of <code>length</code> bytes from
the styling position and then increases the styling position by <code>length</code>, ready for
the next call. The <code>length</code> styling bytes pointed at by <code>styles</code> should
not contain any bits not set in mask.</p>
<p><b id="SCI_SETLINESTATE">SCI_SETLINESTATE(int line, int value)</b><br />
<b id="SCI_GETLINESTATE">SCI_GETLINESTATE(int line)</b><br />
As well as the 8 bits of lexical state stored for each character there is also an integer
stored for each line. This can be used for longer lived parse states such as what the current
scripting language is in an ASP page. Use <code>SCI_SETLINESTATE</code> to set the integer
value and <code>SCI_GETLINESTATE</code> to get the value.
Changing the value produces a <a class="message" href="#SC_MOD_CHANGELINESTATE">SC_MOD_CHANGELINESTATE</a> notification.
</p>
<p><b id="SCI_GETMAXLINESTATE">SCI_GETMAXLINESTATE</b><br />
This returns the last line that has any line state.</p>
<h2 id="StyleDefinition">Style definition</h2>
<p>While the style setting messages mentioned above change the style numbers associated with
text, these messages define how those style numbers are interpreted visually. There are 256
lexer styles that can be set, numbered 0 to <code>STYLE_MAX</code> (255). Unless you use <a
class="message" href="#SCI_SETSTYLEBITS"><code>SCI_SETSTYLEBITS</code></a> to change the number
of style bits, styles 0 to 31 are used to set the text attributes. There are also some
predefined numbered styles starting at 32, The following <code>STYLE_</code>* constants are
defined.</p>
<table cellpadding="1" cellspacing="2" border="0" summary="Preset styles">

</table>
<p>For each style you can set the font name, size and use of bold, italic and underline,
foreground and background colour and the character set. You can also choose to hide text with a
given style, display all characters as upper or lower case and fill from the last character on
a line to the end of the line (for embedded languages). There is also an experimental attribute
to make text read-only.</p>
<p>It is entirely up to you how you use styles. If you want to use syntax colouring you might
use style 0 for white space, style 1 for numbers, style 2 for keywords, style 3 for strings,
style 4 for preprocessor, style 5 for operators, and so on.</p>

These messages (plus <a class="message"
href="#SCI_STYLESETCHARACTERSET"><code>SCI_STYLESETCHARACTERSET</code></a>) set the font
attributes that are used to match the fonts you request to those available. The
<code>fontName</code> is a zero terminated string holding the name of a font. Under Windows,
only the first 32 characters of the name are used and the name is not case sensitive. For
internal caching, Scintilla tracks fonts by name and does care about the casing of font names,
so please be consistent. On GTK+, Pango is used to display text.</p>
<p>Sizes can be set to a whole number of points with <code>SCI_STYLESETSIZE</code>
or to a fractional point size in hundredths of a point with <code>SCI_STYLESETSIZEFRACTIONAL</code>
by multiplying the size by 100 (<code>SC_FONT_SIZE_MULTIPLIER</code>).
For example, a text size of 9.4 points is set with <code>SCI_STYLESETSIZEFRACTIONAL(&lt;style&gt;, 940)</code>.
</p>
<p>The weight or boldness of a font can be set with <code>SCI_STYLESETBOLD</code>
or <code>SCI_STYLESETWEIGHT</code>. The weight is a number between 1 and 999 with 1 being very light
and 999 very heavy. While any value can be used, fonts often only support between 2 and 4 weights with three weights
being common enough to have symbolic names:
<code>SC_WEIGHT_NORMAL</code> (400),
<code>SC_WEIGHT_SEMIBOLD</code> (600), and
<code>SC_WEIGHT_BOLD</code> (700).
The <code>SCI_STYLESETBOLD</code> message takes a boolean argument with 0 choosing <code>SC_WEIGHT_NORMAL</code>
and 1 <code>SC_WEIGHT_BOLD</code>.

If the last character in the line has a style with this attribute set, the remainder of the
line up to the right edge of the window is filled with the background colour set for the last
character. This is useful when a document contains embedded sections in another language such
as HTML pages with embedded JavaScript. By setting <code>eolFilled</code> to <code>true</code>
and a consistent background colour (different from the background colour set for the HTML
styles) to all JavaScript styles then JavaScript sections will be easily distinguished from
HTML.</p>

<b id="SCI_STYLEGETCHARACTERSET">SCI_STYLEGETCHARACTERSET(int styleNumber)</b><br />
You can set a style to use a different character set than the default. The places where such
characters sets are likely to be useful are comments and literal strings. For example,
<code>SCI_STYLESETCHARACTERSET(SCE_C_STRING, SC_CHARSET_RUSSIAN)</code> would ensure that
strings in Russian would display correctly in C and C++ (<code>SCE_C_STRING</code> is the style
number used by the C and C++ lexer to display literal strings; it has the value 6). This
feature works differently on Windows and GTK+.</p>
<p>The character sets supported on Windows are:<br />
<code>SC_CHARSET_ANSI</code>, <code>SC_CHARSET_ARABIC</code>, <code>SC_CHARSET_BALTIC</code>,
<code>SC_CHARSET_CHINESEBIG5</code>, <code>SC_CHARSET_DEFAULT</code>,
<code>SC_CHARSET_EASTEUROPE</code>, <code>SC_CHARSET_GB2312</code>,
<code>SC_CHARSET_GREEK</code>, <code>SC_CHARSET_HANGUL</code>, <code>SC_CHARSET_HEBREW</code>,
<code>SC_CHARSET_JOHAB</code>, <code>SC_CHARSET_MAC</code>, <code>SC_CHARSET_OEM</code>,
<code>SC_CHARSET_RUSSIAN</code> (code page 1251),
<code>SC_CHARSET_SHIFTJIS</code>, <code>SC_CHARSET_SYMBOL</code>, <code>SC_CHARSET_THAI</code>,
<code>SC_CHARSET_TURKISH</code>, and <code>SC_CHARSET_VIETNAMESE</code>.</p>
<p>The character sets supported on GTK+ are:<br />
<code>SC_CHARSET_ANSI</code>, <code>SC_CHARSET_CYRILLIC</code> (code page 1251),
<code>SC_CHARSET_EASTEUROPE</code>,
<code>SC_CHARSET_GB2312</code>, <code>SC_CHARSET_HANGUL</code>,

<p><b id="SCI_STYLESETCASE">SCI_STYLESETCASE(int styleNumber, int caseMode)</b><br />
<b id="SCI_STYLEGETCASE">SCI_STYLEGETCASE(int styleNumber)</b><br />
The value of caseMode determines how text is displayed. You can set upper case
(<code>SC_CASE_UPPER</code>, 1) or lower case (<code>SC_CASE_LOWER</code>, 2) or display
normally (<code>SC_CASE_MIXED</code>, 0). This does not change the stored text, only how it is
displayed.</p>
<p><b id="SCI_STYLESETVISIBLE">SCI_STYLESETVISIBLE(int styleNumber, bool visible)</b><br />
<b id="SCI_STYLEGETVISIBLE">SCI_STYLEGETVISIBLE(int styleNumber)</b><br />
Text is normally visible. However, you can completely hide it by giving it a style with the

<b id="SCI_STYLEGETCHANGEABLE">SCI_STYLEGETCHANGEABLE(int styleNumber)</b><br />
This is an experimental and incompletely implemented style attribute. The default setting is
<code>changeable</code> set <code>true</code> but when set <code>false</code> it makes text
read-only. Currently it only stops the caret from being within not-changeable text and does not
yet stop deleting a range that contains not-changeable text.</p>
<p><b id="SCI_STYLESETHOTSPOT">SCI_STYLESETHOTSPOT(int styleNumber, bool

<b id="SCI_STYLEGETHOTSPOT">SCI_STYLEGETHOTSPOT(int styleNumber)</b><br />
This style is used to mark ranges of text that can detect mouse clicks.
The cursor changes to a hand over hotspots, and the foreground, and background colours
may change and an underline appear to indicate that these areas are sensitive to clicking.
This may be used to allow hyperlinks to other documents.</p>
<h2 id="CaretAndSelectionStyles">Caret, selection, and hotspot styles</h2>
<p>The selection is shown by changing the foreground and/or background colours. If one of these
is not set then that attribute is not changed for the selection. The default is to show the
selection by changing the background to light gray and leaving the foreground the same as when
it was not selected. When there is no selection, the current insertion point is marked by the
text caret. This is a vertical line that is normally blinking on and off to attract the users
attention.</p>

You can choose to make the background colour of the line containing the caret different with
these messages. To do this, set the desired background colour with
<code>SCI_SETCARETLINEBACK</code>, then use <code>SCI_SETCARETLINEVISIBLE(true)</code> to
enable the effect. You can cancel the effect with <code>SCI_SETCARETLINEVISIBLE(false)</code>.
The two <code>SCI_GETCARET*</code> functions return the state and the colour. This form of
background colouring has highest priority when a line has markers that would otherwise change
the background colour.
The caret line may also be drawn translucently which allows other background colours to show
through. This is done by setting the alpha (translucency) value by calling
SCI_SETCARETLINEBACKALPHA. When the alpha is not SC_ALPHA_NOALPHA,
the caret line is drawn after all other features so will affect the colour of all other features.

<b id="SCI_GETCARETPERIOD">SCI_GETCARETPERIOD</b><br />
The rate at which the caret blinks can be set with <code>SCI_SETCARETPERIOD</code> which
determines the time in milliseconds that the caret is visible or invisible before changing
state. Setting the period to 0 stops the caret blinking. The default value is 500 milliseconds.
<code>SCI_GETCARETPERIOD</code> returns the current setting.</p>
<p><b id="SCI_SETCARETSTYLE">SCI_SETCARETSTYLE(int style)</b><br />
<b id="SCI_GETCARETSTYLE">SCI_GETCARETSTYLE</b><br />
The style of the caret can be set with <code>SCI_SETCARETSTYLE</code> to be a line caret
(CARETSTYLE_LINE=1), a block caret (CARETSTYLE_BLOCK=2) or to not draw at all
(CARETSTYLE_INVISIBLE=0). The default value is the line caret (CARETSTYLE_LINE=1).
You can determine the current caret style setting using <code>SCI_GETCARETSTYLE</code>.</p>
<p>The block character draws most combining and multibyte character sequences successfully,
though some fonts like Thai Fonts (and possibly others) can sometimes appear strange when
the cursor is positioned at these characters, which may result in only drawing a part of the
cursor character sequence. This is most notable on Windows platforms.</p>
<p><b id="SCI_SETCARETWIDTH">SCI_SETCARETWIDTH(int pixels)</b><br />
<b id="SCI_GETCARETWIDTH">SCI_GETCARETWIDTH</b><br />
The width of the line caret can be set with <code>SCI_SETCARETWIDTH</code> to a value of
0, 1, 2 or 3 pixels. The default width is 1 pixel. You can read back the current width with
<code>SCI_GETCARETWIDTH</code>. A width of 0 makes the caret invisible (added at version
1.50), similar to setting the caret style to CARETSTYLE_INVISIBLE (though not interchangable).
This setting only affects the width of the cursor when the cursor style is set to line caret
mode, it does not affect the width for a block caret.</p>

<p><b id="SCI_SETCONTROLCHARSYMBOL">SCI_SETCONTROLCHARSYMBOL(int symbol)</b><br />
<b id="SCI_GETCONTROLCHARSYMBOL">SCI_GETCONTROLCHARSYMBOL</b><br />
By default, Scintilla displays control characters (characters with codes less than 32) in a
rounded rectangle as ASCII mnemonics: "NUL", "SOH", "STX", "ETX", "EOT", "ENQ", "ACK", "BEL",
"BS", "HT", "LF", "VT", "FF", "CR", "SO", "SI", "DLE", "DC1", "DC2", "DC3", "DC4", "NAK",
"SYN", "ETB", "CAN", "EM", "SUB", "ESC", "FS", "GS", "RS", "US". These mnemonics come from the
early days of signaling, though some are still used (LF = Line Feed, BS = Back Space, CR =
Carriage Return, for example).</p>
<p>You can choose to replace these mnemonics by a nominated symbol with an ASCII code in the
range 32 to 255. If you set a symbol value less than 32, all control characters are displayed
as mnemonics. The symbol you set is rendered in the font of the style set for the character.
You can read back the current symbol with the <code>SCI_GETCONTROLCHARSYMBOL</code> message.
The default symbol value is 0.</p>

These messages set, get or toggle the caretSticky setting which controls when the last position
of the caret on the line is saved.</p>
<p>When set to <code>SC_CARETSTICKY_OFF</code> (0), the sticky flag is off; all text changes
(and all caret position changes) will remember the
caret's new horizontal position when moving to different lines. This is the default.</p>
<p>When set to <code>SC_CARETSTICKY_ON</code> (1), the sticky flag is on, and the only thing which will cause the editor to remember the
horizontal caret position is moving the caret with mouse or keyboard (left/right arrow keys, home/end keys, etc). </p>
<p>When set to <code>SC_CARETSTICKY_WHITESPACE</code> (2), the caret acts like mode 0 (sticky off) except under one
special case; when space or tab characters are inserted. (Including pasting <b>only space/tabs</b> -- undo, redo,
etc. do not exhibit this behavior..).</p>
<p><code>SCI_TOGGLECARETSTICKY</code> switches from <code>SC_CARETSTICKY_ON</code> and <code>SC_CARETSTICKY_WHITESPACE</code>
to <code>SC_CARETSTICKY_OFF</code> and from <code>SC_CARETSTICKY_OFF</code> to <code>SC_CARETSTICKY_ON</code>.</p>
<h2 id="Margins">Margins</h2>
<p>There may be up to five margins, numbered 0 to <code>SC_MAX_MARGIN</code> (4)
to the left of the text display, plus a gap either side of
the text. Each margin can be set to display only symbols, line numbers, or text with <a
class="message" href="#SCI_SETMARGINTYPEN"><code>SCI_SETMARGINTYPEN</code></a>.
Textual margins may also display symbols.
The markers
that can be displayed in each margin are set with <a class="message"
href="#SCI_SETMARGINMASKN"><code>SCI_SETMARGINMASKN</code></a>. Any markers not associated with
a visible margin will be displayed as changes in background colour in the text. A width in
pixels can be set for each margin. Margins with a zero width are ignored completely. You can
choose if a mouse click in a margin sends a <a class="message"
href="#SCN_MARGINCLICK"><code>SCN_MARGINCLICK</code></a> notification to the container or
selects a line of text.</p>
<p>The margins are numbered 0 to 4. Using a margin number outside the valid range has no
effect. By default, margin 0 is set to display line numbers, but is given a width of 0, so it
is hidden. Margin 1 is set to display non-folding symbols and is given a width of 16 pixels, so
it is visible. Margin 2 is set to display the folding symbols, but is given a width of 0, so it
is hidden. Of course, you can set the margins to be whatever you wish.</p>

These two routines set and get the type of a margin. The margin argument should be 0, 1, 2, 3 or 4.
You can use the predefined constants <code>SC_MARGIN_SYMBOL</code> (0) and
<code>SC_MARGIN_NUMBER</code> (1) to set a margin as either a line number or a symbol margin.
A margin with application defined text may use <code>SC_MARGIN_TEXT</code> (4) or
<code>SC_MARGIN_RTEXT</code> (5) to right justify the text.
By convention, margin 0 is used for line numbers and the next two are used for symbols. You can
also use the constants <code>SC_MARGIN_BACK</code> (2) and <code>SC_MARGIN_FORE</code> (3) for
symbol margins that set their background colour to match the STYLE_DEFAULT background and
foreground colours.</p>
<p><b id="SCI_SETMARGINWIDTHN">SCI_SETMARGINWIDTHN(int margin, int pixelWidth)</b><br />
<b id="SCI_GETMARGINWIDTHN">SCI_GETMARGINWIDTHN(int margin)</b><br />
These routines set and get the width of a margin in pixels. A margin with zero width is
invisible. By default, Scintilla sets margin 1 for symbols with a width of 16 pixels, so this
is a reasonable guess if you are not sure what would be appropriate. Line number margins widths
should take into account the number of lines in the document and the line number style. You
could use something like <a class="message"
href="#SCI_TEXTWIDTH"><code>SCI_TEXTWIDTH(STYLE_LINENUMBER, "_99999")</code></a> to get a
suitable width.</p>
<p><b id="SCI_SETMARGINMASKN">SCI_SETMARGINMASKN(int margin, int mask)</b><br />
<b id="SCI_GETMARGINMASKN">SCI_GETMARGINMASKN(int margin)</b><br />
The mask is a 32-bit value. Each bit corresponds to one of 32 logical symbols that can be
displayed in a margin that is enabled for symbols. There is a useful constant,
<code>SC_MASK_FOLDERS</code> (0xFE000000 or -33554432), that is a mask for the 7 logical
symbols used to denote folding. You can assign a wide range of symbols and colours to each of
the 32 logical symbols, see <a href="#Markers">Markers</a> for more information. If <code>(mask
&amp; SC_MASK_FOLDERS)==0</code>, the margin background colour is controlled by style 33 (<a
class="message" href="#StyleDefinition"><code>STYLE_LINENUMBER</code></a>).</p>
<p>You add logical markers to a line with <a class="message"
href="#SCI_MARKERADD"><code>SCI_MARKERADD</code></a>. If a line has an associated marker that
does not appear in the mask of any margin with a non-zero width, the marker changes the
background colour of the line. For example, suppose you decide to use logical marker 10 to mark
lines with a syntax error and you want to show such lines by changing the background colour.
The mask for this marker is 1 shifted left 10 times (1&lt;&lt;10) which is 0x400. If you make
sure that no symbol margin includes 0x400 in its mask, any line with the marker gets the
background colour changed.</p>
<p>To set a non-folding margin 1 use <code>SCI_SETMARGINMASKN(1, ~SC_MASK_FOLDERS)</code>
which is the default set by Scintilla.
To set a folding margin 2 use <code>SCI_SETMARGINMASKN(2, SC_MASK_FOLDERS)</code>.
<code>~SC_MASK_FOLDERS</code> is 0x1FFFFFF in hexadecimal or 33554431
decimal. Of course, you may need to display all 32 symbols in a margin, in which case use
<code>SCI_SETMARGINMASKN(margin, -1)</code>.</p>

Text margins are created with the type SC_MARGIN_TEXT or SC_MARGIN_RTEXT.
A different string may be set for each line with <code>SCI_MARGINSETTEXT</code>.
The whole of the text margin on a line may be displayed in a particular style with
<code>SCI_MARGINSETSTYLE</code> or each character may be individually styled with
<code>SCI_MARGINSETSTYLES</code> which uses an array of bytes with each byte setting the style
of the corresponding text byte similar to <code>SCI_SETSTYLINGEX</code>.
Setting a text margin will cause a
<a class="message" href="#SC_MOD_CHANGEMARGIN"><code>SC_MOD_CHANGEMARGIN</code></a>

<b id="SCI_MARGINSETSTYLEOFFSET">SCI_MARGINSETSTYLEOFFSET(int style)</b><br />
<b id="SCI_MARGINGETSTYLEOFFSET">SCI_MARGINGETSTYLEOFFSET</b><br />
Margin styles may be completely separated from standard text styles by setting a style offset. For example,
<code>SCI_MARGINSETSTYLEOFFSET(256)</code> would allow the margin styles to be numbered from
256 upto 511 so they do not overlap styles set by lexers. Each style number set with <code>SCI_MARGINSETSTYLE</code>
or <code>SCI_MARGINSETSTYLES</code> has the offset added before looking up the style.
</p>
<p>
Always call <a class="message" href="#SCI_ALLOCATEEXTENDEDSTYLES">SCI_ALLOCATEEXTENDEDSTYLES</a>

<code>SC_MARGINOPTION_SUBLINESELECT</code>=1, which controls how wrapped lines are selected when clicking
on margin in front of them. If <code>SC_MARGINOPTION_SUBLINESELECT</code> is set only sub line of wrapped
line is selected, otherwise whole wrapped line is selected. Margin options are set to

A different string may be set for each line with <code>SCI_ANNOTATIONSETTEXT</code>.
To clear annotations call <code>SCI_ANNOTATIONSETTEXT</code> with a NULL pointer.
The whole of the text ANNOTATION on a line may be displayed in a particular style with
<code>SCI_ANNOTATIONSETSTYLE</code> or each character may be individually styled with
<code>SCI_ANNOTATIONSETSTYLES</code> which uses an array of bytes with each byte setting the style
of the corresponding text byte similar to <code>SCI_SETSTYLINGEX</code>. The text must be set first as it
specifies how long the annotation is so how many bytes of styling to read.
Setting an annotation will cause a
<a class="message" href="#SC_MOD_CHANGEANNOTATION"><code>SC_MOD_CHANGEANNOTATION</code></a>
notification to be sent.
</p>
<p>
The number of lines annotating a line can be retrieved with <code>SCI_ANNOTATIONGETLINES</code>.
All the lines can be cleared of annotations with <code>SCI_ANNOTATIONCLEARALL</code>
which is equivalent to clearing each line (setting to 0) and then deleting other memory used for this feature.
</p>
<p>
Only some style attributes are active in annotations: font, size/sizeFractional, bold/weight, italics, fore, back, and characterSet.

<b id="SCI_ANNOTATIONGETSTYLEOFFSET">SCI_ANNOTATIONGETSTYLEOFFSET</b><br />
Annotation styles may be completely separated from standard text styles by setting a style offset. For example,
<code>SCI_ANNOTATIONSETSTYLEOFFSET(512)</code> would allow the annotation styles to be numbered from
512 upto 767 so they do not overlap styles set by lexers (or margins if margins offset is 256).
Each style number set with <code>SCI_ANNOTATIONSETSTYLE</code>
or <code>SCI_ANNOTATIONSETSTYLES</code> has the offset added before looking up the style.
</p>
<p>
Always call <a class="message" href="#SCI_ALLOCATEEXTENDEDSTYLES">SCI_ALLOCATEEXTENDEDSTYLES</a>
before <code>SCI_ANNOTATIONSETSTYLEOFFSET</code> and use the result as the argument to <code>SCI_ANNOTATIONSETSTYLEOFFSET</code>.

<p>To forward a message <code>(WM_XXXX, WPARAM, LPARAM)</code> to Scintilla, you can use
<code>SendMessage(hScintilla, WM_XXXX, WPARAM, LPARAM)</code> where <code>hScintilla</code> is
the handle to the Scintilla window you created as your editor.</p>
<p>While we are on the subject of forwarding messages in Windows, the top level window should
forward any <code>WM_SETTINGCHANGE</code> messages to Scintilla (this is currently used to
collect changes to mouse settings, but could be used for other user interface items in the
future).</p>
<p><b id="SCI_SETBUFFEREDDRAW">SCI_SETBUFFEREDDRAW(bool isBuffered)</b><br />
<b id="SCI_GETBUFFEREDDRAW">SCI_GETBUFFEREDDRAW</b><br />
These messages turn buffered drawing on or off and report the buffered drawing state. Buffered
drawing draws each line into a bitmap rather than directly to the screen and then copies the
bitmap to the screen. This avoids flickering although it does take longer. The default is for
drawing to be buffered.</p>
<p><b id="SCI_SETTWOPHASEDRAW">SCI_SETTWOPHASEDRAW(bool twoPhase)</b><br />
<b id="SCI_GETTWOPHASEDRAW">SCI_GETTWOPHASEDRAW</b><br />
Two phase drawing is a better but slower way of drawing text.
In single phase drawing each run of characters in one style is drawn along with its background.
If a character overhangs the end of a run, such as in "<i>V</i>_" where the
"<i>V</i>" is in a different style from the "_", then this can cause the right hand
side of the "<i>V</i>" to be overdrawn by the background of the "_" which
cuts it off. Two phase drawing
fixes this by drawing all the backgrounds first and then drawing the text in
transparent mode. Two phase drawing may flicker more than single phase
unless buffered drawing is on. The default is for drawing to be two phase.</p>
<p><b id="SCI_SETTECHNOLOGY">SCI_SETTECHNOLOGY(int technology)</b><br />
<b id="SCI_GETTECHNOLOGY">SCI_GETTECHNOLOGY</b><br />
The technology property allows choosing between different drawing APIs and options.
On most platforms, the only choice is <code>SC_TECHNOLOGY_DEFAULT</code> (0).
On Windows Vista or later, <code>SC_TECHNOLOGY_DIRECTWRITE</code> (1)
can be chosen to use the Direct2D and DirectWrite APIs for higher quality antialiased drawing.
Since Direct2D buffers drawing, Scintilla's buffering can be turned off with
<code>SCI_SETBUFFEREDDRAW(0)</code>.</p>
<p><b id="SCI_SETFONTQUALITY">SCI_SETFONTQUALITY(int fontQuality)</b><br />
<b id="SCI_GETFONTQUALITY">SCI_GETFONTQUALITY</b><br />
Manage font quality (antialiasing method). Currently, the following values are available on Windows:
<code>SC_EFF_QUALITY_DEFAULT</code> (backward compatible),
<code>SC_EFF_QUALITY_NON_ANTIALIASED</code>,
<code>SC_EFF_QUALITY_ANTIALIASED</code>,
<code>SC_EFF_QUALITY_LCD_OPTIMIZED</code>.</p>
<p>In case it is necessary to squeeze more options into this property, only a limited number of bits defined
by SC_EFF_QUALITY_MASK (0xf) will be used for quality.</p>
<p><b id="SCI_SETCODEPAGE">SCI_SETCODEPAGE(int codePage)</b><br />
<b id="SCI_GETCODEPAGE">SCI_GETCODEPAGE</b><br />
Scintilla has some support for Japanese, Chinese and Korean DBCS. Use this message with
<code>codePage</code> set to the code page number to set Scintilla to use code page information
to ensure double byte characters are treated as one character rather than two. This also stops
the caret from moving between the two bytes in a double byte character.
Do not use this message to choose between different single byte character sets: it doesn't do that.
Call with
<code>codePage</code> set to zero to disable DBCS support. The default is
<code>SCI_SETCODEPAGE(0)</code>.</p>
<p>Code page <code>SC_CP_UTF8</code> (65001) sets Scintilla into Unicode mode with the document
treated as a sequence of characters expressed in UTF-8. The text is converted to the platform's
normal Unicode encoding before being drawn by the OS and thus can display Hebrew, Arabic,
Cyrillic, and Han characters. Languages which can use two characters stacked vertically in one
horizontal space, such as Thai, will mostly work but there are some issues where the characters
are drawn separately leading to visual glitches. Bi-directional text is not supported. </p>
<p>Code page can be set to 932 (Japanese Shift-JIS), 936 (Simplified Chinese GBK),
949 (Korean Unified Hangul Code), 950 (Traditional Chinese Big5), or 1361 (Korean Johab)
although these may require installation of language specific support.</p>
<p><b id="SCI_SETKEYSUNICODE">SCI_SETKEYSUNICODE(bool keysUnicode)</b><br />
<b id="SCI_GETKEYSUNICODE">SCI_GETKEYSUNICODE</b><br />
On Windows, character keys are normally handled differently depending on whether Scintilla is a wide
or narrow character window with character messages treated as Unicode when wide and as 8 bit otherwise.
Set this property to always treat as Unicode. This option is needed for Delphi.</p>
<p><b id="SCI_SETWORDCHARS">SCI_SETWORDCHARS(&lt;unused&gt;, const char *characters)</b><br />
Scintilla has several functions that operate on words, which are defined to be contiguous
sequences of characters from a particular set of characters. This message defines which
characters are members of that set. The character sets are set to default values before processing this
function.
For example, if you don't allow '_' in your set of characters
use:<br />
<code>SCI_SETWORDCHARS(0, "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789")</code>;</p>
<p><b id="SCI_GETWORDCHARS">SCI_GETWORDCHARS(&lt;unused&gt;, char *characters)</b><br />
This fills the characters parameter with all the characters included in words.
The characters parameter must be large enough to hold all of the characters.
If the characters parameter is 0 then the length that should be allocated
to store the entire set is returned.</p>
<p><b id="SCI_SETWHITESPACECHARS">SCI_SETWHITESPACECHARS(&lt;unused&gt;, const char *characters)</b><br />
<b id="SCI_GETWHITESPACECHARS">SCI_GETWHITESPACECHARS(&lt;unused&gt;, char *characters)</b><br />
Similar to <code>SCI_SETWORDCHARS</code>, this message allows the user to define which chars Scintilla considers
as whitespace. Setting the whitespace chars allows the user to fine-tune Scintilla's behaviour doing
such things as moving the cursor to the start or end of a word; for example, by defining punctuation chars
as whitespace, they will be skipped over when the user presses ctrl+left or ctrl+right.
This function should be called after <code>SCI_SETWORDCHARS</code> as it will
reset the whitespace characters to the default set.
<code>SCI_GETWHITESPACECHARS</code> behaves similarly to <code>SCI_GETWORDCHARS</code>.</p>
<p><b id="SCI_SETPUNCTUATIONCHARS">SCI_SETPUNCTUATIONCHARS(&lt;unused&gt;, const char *characters)</b><br />

<code>SCI_GETPUNCTUATIONCHARS</code> behaves similarly to <code>SCI_GETWORDCHARS</code>.</p>
<p><b id="SCI_SETCHARSDEFAULT">SCI_SETCHARSDEFAULT</b><br />
Use the default sets of word and whitespace characters. This sets whitespace to space, tab and other
characters with codes less than 0x20, with word characters set to alphanumeric and '_'.

Scintilla can be told to grab the focus with this message. This is needed more on GTK+ where
focus handling is more complicated than on Windows.</p>
<p>The internal focus flag can be set with <code>SCI_SETFOCUS</code>. This is used by clients
that have complex focus requirements such as having their own window that gets the real focus
but with the need to indicate that Scintilla has the logical focus.</p>

Up to two characters can be highlighted in a 'brace highlighting style', which is defined as
style number <a class="message" href="#StyleDefinition"><code>STYLE_BRACELIGHT</code></a> (34).
If you have enabled indent guides, you may also wish to highlight the indent that corresponds
with the brace. You can locate the column with <a class="message"
href="#SCI_GETCOLUMN"><code>SCI_GETCOLUMN</code></a> and highlight the indent with <a
class="message" href="#SCI_SETHIGHLIGHTGUIDE"><code>SCI_SETHIGHLIGHTGUIDE</code></a>.</p>
<p><b id="SCI_BRACEBADLIGHT">SCI_BRACEBADLIGHT(int pos1)</b><br />
If there is no matching brace then the <a class="jump" href="#StyleDefinition">brace
badlighting style</a>, style <code>STYLE_BRACEBAD</code> (35), can be used to show the brace
that is unmatched. Using a position of <code>INVALID_POSITION</code> (-1) removes the
highlight.</p>
<p><b id="#SCI_BRACEHIGHLIGHTINDICATOR">SCI_BRACEHIGHLIGHTINDICATOR(bool useBraceHighlightIndicator, int indicatorNumber)</b><br />
Use specified indicator to highlight matching braces instead of changing their style.</p>
<p><b id="#SCI_BRACEBADLIGHTINDICATOR">SCI_BRACEBADLIGHTINDICATOR(bool useBraceBadLightIndicator, int indicatorNumber)</b><br />
Use specified indicator to highlight non matching brace instead of changing its style.</p>
<p><b id="SCI_BRACEMATCH">SCI_BRACEMATCH(int pos, int maxReStyle)</b><br />
The <code>SCI_BRACEMATCH</code> message finds a corresponding matching brace given
<code>pos</code>, the position of one brace. The brace characters handled are '(', ')', '[',
']', '{', '}', '&lt;', and '&gt;'. The search is forwards from an opening brace and backwards
from a closing brace. If the character at position is not a brace character, or a matching
brace cannot be found, the return value is -1. Otherwise, the return value is the position of
the matching brace.</p>
<p>A match only occurs if the style of the matching brace is the same as the starting brace or
the matching brace is beyond the end of styling. Nested braces are handled correctly. The
<code>maxReStyle</code> parameter must currently be 0 - it may be used in the future to limit
the length of brace searches.</p>
<h2 id="TabsAndIndentationGuides">Tabs and Indentation Guides</h2>
<p>Indentation (the white space at the start of a line) is often used by programmers to clarify
program structure and in some languages, for example Python, it may be part of the language
syntax. Tabs are normally used in editors to insert a tab character or to pad text with spaces
up to the next tab.</p>
<p>Scintilla can be set to treat tab and backspace in the white space at the start of a line in
a special way: inserting a tab indents the line to the next indent position rather than just
inserting a tab at the current character position and backspace unindents the line rather than
deleting a character. Scintilla can also display indentation guides (vertical lines) to help
you to generate code.</p>

<h2 id="Markers">Markers</h2>
<p>There are 32 markers, numbered 0 to <code>MARKER_MAX</code> (31), and you can assign any combination of them to each
line in the document. Markers appear in the <a class="jump" href="#Margins">selection
margin</a> to the left of the text. If the selection margin is set to zero width, the
background colour of the whole line is changed instead. Marker numbers 25 to 31 are used by
Scintilla in folding margins, and have symbolic names of the form <code>SC_MARKNUM_</code>*,
for example <code>SC_MARKNUM_FOLDEROPEN</code>.</p>
<p>Marker numbers 0 to 24 have no pre-defined function; you can use them to mark syntax errors
or the current point of execution, break points, or whatever you need marking. If you do not
need folding, you can use all 32 for any purpose you wish.</p>
<p>Each marker number has a symbol associated with it. You can also set the foreground and
background colour for each marker number, so you can use the same symbol more than once with
different colouring for different uses. Scintilla has a set of symbols you can assign
(<code>SC_MARK_</code>*) or you can use characters. By default, all 32 markers are set to
<code>SC_MARK_CIRCLE</code> with a black foreground and a white background.</p>
<p>The markers are drawn in the order of their numbers, so higher numbered markers appear on
top of lower numbered ones. Markers try to move with their text by tracking where the start of
their line moves. When a line is deleted, its markers are combined, by an <code>OR</code>
operation, with the markers of the previous line.</p>

<p><b id="SCI_MARKERDEFINE">SCI_MARKERDEFINE(int markerNumber, int markerSymbols)</b><br />
This message associates a marker number in the range 0 to 31 with one of the marker symbols or
an ASCII character. The general-purpose marker symbols currently available are:<br />
<code>SC_MARK_CIRCLE</code>, <code>SC_MARK_ROUNDRECT</code>, <code>SC_MARK_ARROW</code>,
<code>SC_MARK_SMALLRECT</code>, <code>SC_MARK_SHORTARROW</code>, <code>SC_MARK_EMPTY</code>,
<code>SC_MARK_ARROWDOWN</code>, <code>SC_MARK_MINUS</code>, <code>SC_MARK_PLUS</code>,
<code>SC_MARK_ARROWS</code>, <code>SC_MARK_DOTDOTDOT</code>,
<code>SC_MARK_BACKGROUND</code>, <code>SC_MARK_LEFTRECT</code>,
<code>SC_MARK_FULLRECT</code>, and <code>SC_MARK_UNDERLINE</code>.</p>
<p>The <code>SC_MARK_BACKGROUND</code> marker changes the background colour of the line only.
The <code>SC_MARK_FULLRECT</code> symbol mirrors this, changing only the margin background colour.
<code>SC_MARK_UNDERLINE</code> draws an underline across the text.
The <code>SC_MARK_EMPTY</code> symbol is invisible, allowing client code to track the movement
of lines. You would also use it if you changed the folding style and wanted one or more of the
<code>SC_FOLDERNUM_</code>* markers to have no associated symbol.</p>
<p>Applications may use the marker symbol <code>SC_MARK_AVAILABLE</code> to indicate that
plugins may allocate that marker number.
</p>
<p>There are also marker symbols designed for use in the folding margin in a flattened tree
style.<br />
<code>SC_MARK_BOXMINUS</code>, <code>SC_MARK_BOXMINUSCONNECTED</code>,
<code>SC_MARK_BOXPLUS</code>, <code>SC_MARK_BOXPLUSCONNECTED</code>,
<code>SC_MARK_CIRCLEMINUS</code>, <code>SC_MARK_CIRCLEMINUSCONNECTED</code>,
<code>SC_MARK_CIRCLEPLUS</code>, <code>SC_MARK_CIRCLEPLUSCONNECTED</code>,
<code>SC_MARK_LCORNER</code>, <code>SC_MARK_LCORNERCURVE</code>, <code>SC_MARK_TCORNER</code>,
<code>SC_MARK_TCORNERCURVE</code>, and <code>SC_MARK_VLINE</code>.</p>
Characters can be used as markers by adding the ASCII value of the character to
<code>SC_MARK_CHARACTER</code> (10000). For example, to use 'A' (ASCII code 65) as marker
number 1 use:<br />
<code>SCI_MARKERDEFINE(1, SC_MARK_CHARACTER+65)</code>. <br />
<p>The marker numbers <code>SC_MARKNUM_FOLDER</code> and <code>SC_MARKNUM_FOLDEROPEN</code> are
used for showing that a fold is present and open or closed. Any symbols may be assigned for
this purpose although the (<code>SC_MARK_PLUS</code>, <code>SC_MARK_MINUS</code>) pair or the
(<code>SC_MARK_ARROW</code>, <code>SC_MARK_ARROWDOWN</code>) pair are good choices. As well as
these two, more assignments are needed for the flattened tree style:
<code>SC_MARKNUM_FOLDEREND</code>, <code>SC_MARKNUM_FOLDERMIDTAIL</code>,
<code>SC_MARKNUM_FOLDEROPENMID</code>, <code>SC_MARKNUM_FOLDERSUB</code>, and
<code>SC_MARKNUM_FOLDERTAIL</code>. The bits used for folding are specified by
<code>SC_MASK_FOLDERS</code>, which is commonly used as an argument to
<code>SCI_SETMARGINMASKN</code> when defining a margin to be used for folding.</p>
<p>This table shows which <code>SC_MARK_</code>* symbols should be assigned to which
<code>SC_MARKNUM_</code>* marker numbers to obtain four folding styles: Arrow (mimics
Macintosh), plus/minus shows folded lines as '+' and opened folds as '-', Circle tree, Box
tree.</p>

The width and height must previously been set with the <code>SCI_RGBAIMAGESETWIDTH</code> and
<code>SCI_RGBAIMAGESETHEIGHT</code> messages.</p>
<p>A scale factor in percent may be set with <code>SCI_RGBAIMAGESETSCALE</code>. This is useful on OS X with
a retina display where each display unit is 2 pixels: use a factor of 200 so that each image pixel is dsplayed using a screen pixel.
The default scale, 100, will stretch each image pixel to cover 4 screen pixels on a retina display.</p>

<p><b id="SCI_MARKERADD">SCI_MARKERADD(int line, int markerNumber)</b><br />
This message adds marker number <code>markerNumber</code> to a line. The message returns -1 if
this fails (illegal line number, out of memory) or it returns a marker handle number that
identifies the added marker. You can use this returned handle with <a class="message"
href="#SCI_MARKERLINEFROMHANDLE"><code>SCI_MARKERLINEFROMHANDLE</code></a> to find where a
marker is after moving or combining lines and with <a class="message"
href="#SCI_MARKERDELETEHANDLE"><code>SCI_MARKERDELETEHANDLE</code></a> to delete the marker

to see if any of the markers are already present on the targeted line.</p>
<p><b id="SCI_MARKERDELETE">SCI_MARKERDELETE(int line, int markerNumber)</b><br />
This searches the given line number for the given marker number and deletes it if it is
present. If you added the same marker more than once to the line, this will delete one copy
each time it is used. If you pass in a marker number of -1, all markers are deleted from the
line.</p>
<p><b id="SCI_MARKERDELETEALL">SCI_MARKERDELETEALL(int markerNumber)</b><br />
This removes markers of the given number from all lines. If markerNumber is -1, it deletes all
markers from all lines.</p>
<p><b id="SCI_MARKERGET">SCI_MARKERGET(int line)</b><br />
This returns a 32-bit integer that indicates which markers were present on the line. Bit 0 is
set if marker 0 is present, bit 1 for marker 1 and so on.</p>
<p><b id="SCI_MARKERNEXT">SCI_MARKERNEXT(int lineStart, int markerMask)</b><br />
<b id="SCI_MARKERPREVIOUS">SCI_MARKERPREVIOUS(int lineStart, int markerMask)</b><br />
These messages search efficiently for lines that include a given set of markers. The search
starts at line number <code>lineStart</code> and continues forwards to the end of the file
(<code>SCI_MARKERNEXT</code>) or backwards to the start of the file
(<code>SCI_MARKERPREVIOUS</code>). The <code>markerMask</code> argument should have one bit set
for each marker you wish to find. Set bit 0 to find marker 0, bit 1 for marker 1 and so on. The
message returns the line number of the first line that contains one of the markers in
<code>markerMask</code> or -1 if no marker is found.</p>
<p><b id="SCI_MARKERLINEFROMHANDLE">SCI_MARKERLINEFROMHANDLE(int markerHandle)</b><br />
The <code>markerHandle</code> argument is an identifier for a marker returned by <a
class="message" href="#SCI_MARKERADD"><code>SCI_MARKERADD</code></a>. This function searches
the document for the marker with this handle and returns the line number that contains it or -1
if it is not found.</p>
<p><b id="SCI_MARKERDELETEHANDLE">SCI_MARKERDELETEHANDLE(int markerHandle)</b><br />
The <code>markerHandle</code> argument is an identifier for a marker returned by <a

<h2 id="Indicators">Indicators</h2>
<p>Indicators are used to display additional information over the top of styling.
They can be used to show, for example, syntax errors, deprecated names and bad indentation
by drawing underlines under text or boxes around text. Originally, Scintilla stored indicator information in
the style bytes but this has proved limiting, so now up to 32 separately stored indicators may be used.
While style byte indicators currently still work, they will soon be removed so all the bits in each style
byte can be used for lexical states.</p>
<p>Indicators may be displayed as simple underlines, squiggly underlines, a
line of small 'T' shapes, a line of diagonal hatching, a strike-out or a rectangle around the text.</p>
<p>The <code>SCI_INDIC*</code> messages allow you to get and set the visual appearance of the
indicators. They all use an <code>indicatorNumber</code> argument in the range 0 to INDIC_MAX(31)
to set the indicator to style. To prevent interference the set of indicators is divided up into a range for use
by lexers (0..7) and a range for use by containers
(8=<code>INDIC_CONTAINER</code> .. 31=<code>INDIC_MAX</code>).</p>

<h3 id="FindIndicators">OS X Find Indicator</h3>
<p>On OS X search matches are highlighted with an animated gold rounded rectangle.
The indicator shows, then briefly grows 25% and shrinks to the original size to draw the user's attention.
While this feature is currently only implemented on OS X, it may be implemented on other platforms

These two messages show and animate the find indicator. The indicator remains visible with
<code>SCI_FINDINDICATORSHOW</code> and fades out after showing for half a second with
<code>SCI_FINDINDICATORFLASH</code>.
<code>SCI_FINDINDICATORSHOW</code> behaves similarly to the OS X TextEdit and Safari applications
and is best suited to editing documentation where the search target is often a word.
<code>SCI_FINDINDICATORFLASH</code> is similar to Xcode and is suited to editing source code
where the match will often be located next to operators which would otherwise be hidden under the indicator's
padding.
</p>
<p><b id="SCI_FINDINDICATORHIDE">SCI_FINDINDICATORHIDE</b><br />
This message hides the find indicator.
</p>
<h3 id="StyleByteIndicators">Style Byte Indicators (deprecated)</h3>
<p>By default, Scintilla organizes the style byte associated with each text byte as 5 bits of
style information (for 32 styles) and 3 bits of indicator information for 3 independent
indicators so that, for example, syntax errors, deprecated names and bad indentation could all
be displayed at once.</p>
<p>The indicators are set using <a class="message"
href="#SCI_STARTSTYLING"><code>SCI_STARTSTYLING</code></a> with a <code>INDICS_MASK</code> mask
and <a class="message" href="#SCI_SETSTYLING"><code>SCI_SETSTYLING</code></a> with the values
<code>INDIC0_MASK</code>, <code>INDIC1_MASK</code> and <code>INDIC2_MASK</code>.</p>
<p>If you are using indicators in a buffer that has a lexer active
(see <a class="message" href="#SCI_SETLEXER"><code>SCI_SETLEXER</code></a>),
you must save lexing state information before setting any indicators and restore it afterwards.
Use <a class="message" href="#SCI_GETENDSTYLED"><code>SCI_GETENDSTYLED</code></a>
to retrieve the current "styled to" position and
<a class="message" href="#SCI_STARTSTYLING"><code>SCI_STARTSTYLING</code></a>
to reset the styling position and mask (<code>0x1f </code> in the default layout of 5 style bits and 3 indicator bits)
when you are done.</p>
<p>The number of bits used for styles can be altered with <a class="message"
href="#SCI_SETSTYLEBITS"><code>SCI_SETSTYLEBITS</code></a> from 0 to 8 bits. The remaining bits
can be used for indicators, so there can be from 1 to 8 indicators. However, the
<code>INDIC*_MASK</code> constants defined in <code>Scintilla.h</code> all assume 5 bits of
styling information and 3 indicators. If you use a different arrangement, you must define your
own constants.</p>
<h2 id="Autocompletion">Autocompletion</h2>
<p>Autocompletion displays a list box showing likely identifiers based upon the user's typing.
The user chooses the currently selected item by pressing the tab character or another character
that is a member of the fillup character set defined with <code>SCI_AUTOCSETFILLUPS</code>.
Autocompletion is triggered by your application. For example, in C if you detect that the user
has just typed <code>fred.</code> you could look up <code>fred</code>, and if it has a known
list of members, you could offer them in an autocompletion list. Alternatively, you could
monitor the user's typing and offer a list of likely items once their typing has narrowed down
the choice to a reasonable list. As yet another alternative, you could define a key code to
activate the list.</p>
<p>When the user makes a selection from the list the container is sent a <code><a class="message"
href="#SCN_AUTOCSELECTION">SCN_AUTOCSELECTION</a></code> <a class="jump"
href="#Notifications">notification message</a>. On return from the notification Scintilla will insert
the selected text unless the autocompletion list has been cancelled, for example by the container sending
<code><a class="message" href="#SCI_AUTOCCANCEL">SCI_AUTOCCANCEL</a></code>.</p>
<p>To make use of autocompletion you must monitor each character added to the document. See
<code>SciTEBase::CharAdded()</code> in SciTEBase.cxx for an example of autocompletion.</p>

<p><b id="SCI_AUTOCSHOW">SCI_AUTOCSHOW(int lenEntered, const char *list)</b><br />
This message causes a list to be displayed. <code>lenEntered</code> is the number of
characters of the word already entered and <code>list</code> is the list of words separated by
separator characters. The initial separator character is a space but this can be set or got
with <a class="message" href="#SCI_AUTOCSETSEPARATOR"><code>SCI_AUTOCSETSEPARATOR</code></a>
and <a class="message"
href="#SCI_AUTOCGETSEPARATOR"><code>SCI_AUTOCGETSEPARATOR</code></a>.</p>
<p>With default settings, the list of words should be in sorted order.
If set to ignore case mode with <a class="message" href="#SCI_AUTOCSETIGNORECASE"><code>SCI_AUTOCSETIGNORECASE</code></a>, then
strings are matched after being converted to upper case. One result of this is that the list
should be sorted with the punctuation characters '[', '\', ']', '^', '_', and '`' sorted after
letters.
Alternative handling of list order may be specified with <a class="message" href="#SCI_AUTOCSETORDER">SCI_AUTOCSETORDER</a>
</p>
<p><b id="SCI_AUTOCCANCEL">SCI_AUTOCCANCEL</b><br />
This message cancels any displayed autocompletion list. When in autocompletion mode, the list
should disappear when the user types a character that can not be part of the autocompletion,
such as '.', '(' or '[' when typing an identifier. A set of characters that will cancel
autocompletion can be specified with <a class="message"
href="#SCI_AUTOCSTOPS"><code>SCI_AUTOCSTOPS</code></a>.</p>
<p><b id="SCI_AUTOCACTIVE">SCI_AUTOCACTIVE</b><br />
This message returns non-zero if there is an active autocompletion list and zero if there is
not.</p>
<p><b id="SCI_AUTOCPOSSTART">SCI_AUTOCPOSSTART</b><br />
This returns the value of the current position when <code>SCI_AUTOCSHOW</code> started display
of the list.</p>
<p><b id="SCI_AUTOCCOMPLETE">SCI_AUTOCCOMPLETE</b><br />
This message triggers autocompletion. This has the same effect as the tab key.</p>
<p><b id="SCI_AUTOCSTOPS">SCI_AUTOCSTOPS(&lt;unused&gt;, const char *chars)</b><br />
The <code>chars</code> argument is a string containing a list of characters that will
automatically cancel the autocompletion list. When you start the editor, this list is
empty.</p>
<p><b id="SCI_AUTOCSETSEPARATOR">SCI_AUTOCSETSEPARATOR(char separator)</b><br />
<b id="SCI_AUTOCGETSEPARATOR">SCI_AUTOCGETSEPARATOR</b><br />
These two messages set and get the separator character used to separate words in the
<code>SCI_AUTOCSHOW</code> list. The default is the space character.</p>
<p><b id="SCI_AUTOCSELECT">SCI_AUTOCSELECT(&lt;unused&gt;, const char *select)</b><br />
<b id="SCI_AUTOCGETCURRENT">SCI_AUTOCGETCURRENT</b><br />
This message selects an item in the autocompletion list. It searches the list of words for the
first that matches <code>select</code>. By default, comparisons are case sensitive, but you can
change this with <a class="message"
href="#SCI_AUTOCSETIGNORECASE"><code>SCI_AUTOCSETIGNORECASE</code></a>. The match is character
by character for the length of the <code>select</code> string. That is, if select is "Fred" it
will match "Frederick" if this is the first item in the list that begins with "Fred". If an
item is found, it is selected. If the item is not found, the autocompletion list closes if
auto-hide is true (see <a class="message"
href="#SCI_AUTOCSETAUTOHIDE"><code>SCI_AUTOCSETAUTOHIDE</code></a>).<br />
The current selection index can be retrieved with <code>SCI_AUTOCGETCURRENT</code>.</p>
<p><b id="SCI_AUTOCGETCURRENTTEXT">SCI_AUTOCGETCURRENTTEXT(&lt;unused&gt;, char *text)</b><br />
This message retrieves the current selected text in the autocompletion list. Normally the
<a class="message" href="#SCN_AUTOCSELECTION"><code>SCN_AUTOCSELECTION</code></a> notification
is used instead.</p>
<p>The value is copied to the <code>text</code> buffer, returning the length (not including the
terminating 0). If not found, an empty string is copied to the buffer and 0 is returned.</p>
<p>If the value argument is 0 then the length that should be allocated to store the value is
returned; again, the terminating 0 is not included.</p>
<p><b id="SCI_AUTOCSETCANCELATSTART">SCI_AUTOCSETCANCELATSTART(bool cancel)</b><br />
<b id="SCI_AUTOCGETCANCELATSTART">SCI_AUTOCGETCANCELATSTART</b><br />
The default behavior is for the list to be cancelled if the caret moves to the location it
was at when the list was displayed. By calling this message with a <code>false</code> argument,
the list is not cancelled until the caret moves at least one character before the word being
completed.</p>
<p><b id="SCI_AUTOCSETFILLUPS">SCI_AUTOCSETFILLUPS(&lt;unused&gt;, const char *chars)</b><br />
If a fillup character is typed with an autocompletion list active, the currently selected item
in the list is added into the document, then the fillup character is added. Common fillup
characters are '(', '[' and '.' but others are possible depending on the language. By default,
no fillup characters are set.</p>
<p><b id="SCI_AUTOCSETCHOOSESINGLE">SCI_AUTOCSETCHOOSESINGLE(bool chooseSingle)</b><br />
<b id="SCI_AUTOCGETCHOOSESINGLE">SCI_AUTOCGETCHOOSESINGLE</b><br />
If you use <code>SCI_AUTOCSETCHOOSESINGLE(1)</code> and a list has only one item, it is
automatically added and no list is displayed. The default is to display the list even if there
is only a single item.</p>
<p><b id="SCI_AUTOCSETIGNORECASE">SCI_AUTOCSETIGNORECASE(bool ignoreCase)</b><br />
<b id="SCI_AUTOCGETIGNORECASE">SCI_AUTOCGETIGNORECASE</b><br />
By default, matching of characters to list members is case sensitive. These messages let you
set and get case sensitivity.</p>
<p><b id="SCI_AUTOCSETCASEINSENSITIVEBEHAVIOUR">SCI_AUTOCSETCASEINSENSITIVEBEHAVIOUR(int behaviour)</b><br>
<b id="SCI_AUTOCGETCASEINSENSITIVEBEHAVIOUR">SCI_AUTOCGETCASEINSENSITIVEBEHAVIOUR</b><br>
When autocompletion is set to ignore case (<code>SCI_AUTOCSETIGNORECASE</code>), by default it will
nonetheless select the first list member that matches in a case sensitive way to entered characters.
This corresponds to a behaviour property of <code>SC_CASEINSENSITIVEBEHAVIOUR_RESPECTCASE</code> (0).
If you want autocompletion to ignore case at all, choose <code>SC_CASEINSENSITIVEBEHAVIOUR_IGNORECASE</code> (1).</p>
<p><b id="SCI_AUTOCSETORDER">SCI_AUTOCSETORDER(int order)</b><br>
<b id="SCI_AUTOCGETORDER">SCI_AUTOCGETORDER</b><br>
The default setting <code>SC_ORDER_PRESORTED</code> (0) requires that the list be provided in alphabetical sorted order.
</p>
<p>Sorting the list can be done by Scintilla instead of the application with <code>SC_ORDER_PERFORMSORT</code> (1).
This will take additional time.
</p>
<p>Applications that wish to prioritize some values and show the list in order of priority instead
of alphabetical order can use <code>SC_ORDER_CUSTOM</code> (2).
This requires extra processing in <a class="message" href="#SCI_AUTOCSHOW">SCI_AUTOCSHOW</a> to create a sorted index.
</p>
<p>Setting the order should be done before calling <a class="message" href="#SCI_AUTOCSHOW">SCI_AUTOCSHOW</a>.
</p>
<p><b id="SCI_AUTOCSETAUTOHIDE">SCI_AUTOCSETAUTOHIDE(bool autoHide)</b><br />
<b id="SCI_AUTOCGETAUTOHIDE">SCI_AUTOCGETAUTOHIDE</b><br />
By default, the list is cancelled if there are no viable matches (the user has typed
characters that no longer match a list entry). If you want to keep displaying the original
list, set <code>autoHide</code> to <code>false</code>. This also effects <a class="message"
href="#SCI_AUTOCSELECT"><code>SCI_AUTOCSELECT</code></a>.</p>
<p><b id="SCI_AUTOCSETDROPRESTOFWORD">SCI_AUTOCSETDROPRESTOFWORD(bool dropRestOfWord)</b><br />
<b id="SCI_AUTOCGETDROPRESTOFWORD">SCI_AUTOCGETDROPRESTOFWORD</b><br />
When an item is selected, any word characters following the caret are first erased if
<code>dropRestOfWord</code> is set <code>true</code>. The default is <code>false</code>.</p>

Autocompletion list items may display an image as well as text. Each image is first registered with an integer
type. Then this integer is included in the text of the list separated by a '?' from the text. For example,
"fclose?2 fopen" displays image 2 before the string "fclose" and no image before "fopen".
The images are in either the <a class="jump" href="#XPM">XPM format</a> (<code>SCI_REGISTERIMAGE</code>) or
<a class="jump" href="#RGBA">RGBA format</a> (<code>SCI_REGISTERRGBAIMAGE</code>).
For <code>SCI_REGISTERRGBAIMAGE</code> the width and height must previously been set with
the <a class="message" href="#SCI_RGBAIMAGESETWIDTH"><code>SCI_RGBAIMAGESETWIDTH</code></a> and
<a class="message" href="#SCI_RGBAIMAGESETHEIGHT"><code>SCI_RGBAIMAGESETHEIGHT</code></a> messages.
The set of registered images can be cleared with <code>SCI_CLEARREGISTEREDIMAGES</code> and the '?' separator changed
with <code>SCI_AUTOCSETTYPESEPARATOR</code>.
</p>
<p>
<b id="SCI_AUTOCSETMAXHEIGHT">SCI_AUTOCSETMAXHEIGHT(int rowCount)</b><br />
<b id="SCI_AUTOCGETMAXHEIGHT">SCI_AUTOCGETMAXHEIGHT</b><br />
Get or set the maximum number of rows that will be visible in an autocompletion list. If there are more rows in the list, then a vertical
scrollbar is shown. The default is 5.
</p>
<p>
<b id="SCI_AUTOCSETMAXWIDTH">SCI_AUTOCSETMAXWIDTH(int characterCount)</b><br />
<b id="SCI_AUTOCGETMAXWIDTH">SCI_AUTOCGETMAXWIDTH</b><br />
Get or set the maximum width of an autocompletion list expressed as the number of characters in the longest item that will be totally visible.
If zero (the default) then the list's width is calculated to fit the item with the most characters. Any items that cannot be fully displayed within
the available width are indicated by the presence of ellipsis.
</p>
<h2 id="UserLists">User lists</h2>
<p>User lists use the same internal mechanisms as autocompletion lists, and all the calls
listed for autocompletion work on them; you cannot display a user list at the same time as an
autocompletion list is active. They differ in the following respects:</p>
<p>o The <code><a class="message"
href="#SCI_AUTOCSETCHOOSESINGLE">SCI_AUTOCSETCHOOSESINGLE</a></code> message has no
effect.<br />
o When the user makes a selection you are sent a <code><a class="message"
href="#SCN_USERLISTSELECTION">SCN_USERLISTSELECTION</a></code> <a class="jump"
href="#Notifications">notification message</a> rather than <code><a class="message"
href="#SCN_AUTOCSELECTION">SCN_AUTOCSELECTION</a></code>.</p>
<p>BEWARE: if you have set fillup characters or stop characters, these will still be active
with the user list, and may result in items being selected or the user list cancelled due to
the user typing into the editor.</p>
<p><b id="SCI_USERLISTSHOW">SCI_USERLISTSHOW(int listType, const char *list)</b><br />
The <code>listType</code> parameter is returned to the container as the <code>wParam</code>
field of the <a class="message" href="#SCNotification"><code>SCNotification</code></a>
structure. It must be greater than 0 as this is how Scintilla tells the difference between an
autocompletion list and a user list. If you have different types of list, for example a list of
buffers and a list of macros, you can use <code>listType</code> to tell which one has returned
a selection. </p>
<h2 id="CallTips">Call tips</h2>
<p>Call tips are small windows displaying the arguments to a function and are displayed after
the user has typed the name of the function. They normally display characters using the font
facename, size and character set defined by
<code><a class="message" href="#StyleDefinition">STYLE_DEFAULT</a></code>. You can choose to
use <code><a class="message" href="#StyleDefinition">STYLE_CALLTIP</a></code> to define the
facename, size, foreground and background colours and character set with
<code><a class="message" href="#SCI_CALLTIPUSESTYLE">SCI_CALLTIPUSESTYLE</a></code>.
This also enables support for Tab characters.
There is some interaction between call tips and autocompletion lists in that showing a
call tip cancels any active autocompletion list, and vice versa.</p>
<p>Call tips can highlight part of the text within them. You could use this to highlight the
current argument to a function by counting the number of commas (or whatever separator your
language uses). See <code>SciTEBase::CharAdded()</code> in <code>SciTEBase.cxx</code> for an
example of call tip use.</p>
<p>The mouse may be clicked on call tips and this causes a
<code><a class="message" href="#SCN_CALLTIPCLICK">SCN_CALLTIPCLICK</a></code>
notification to be sent to the container. Small up and down arrows may be displayed within
a call tip by, respectively, including the characters '\001', or '\002'. This is useful
for showing that there are overloaded variants of one function name and that the user can
click on the arrows to cycle through the overloads.</p>
<p>Alternatively, call tips can be displayed when you leave the mouse pointer for a while over
a word in response to the <code><a class="message"
href="#SCN_DWELLSTART">SCN_DWELLSTART</a></code> <a class="jump"
href="#Notifications">notification</a> and cancelled in response to <code><a class="message"
href="#SCN_DWELLEND">SCN_DWELLEND</a></code>. This method could be used in a debugger to give
the value of a variable, or during editing to give information about the word under the
pointer.</p>

</code>
<p><b id="SCI_CALLTIPSHOW">SCI_CALLTIPSHOW(int posStart, const char *definition)</b><br />
This message starts the process by displaying the call tip window. If a call tip is already
active, this has no effect.<br />
<code>posStart</code> is the position in the document at which to align the call tip. The call
tip text is aligned to start 1 line below this character unless you have included up and/or
down arrows in the call tip text in which case the tip is aligned to the right-hand edge of
the rightmost arrow. The assumption is that you will start the text with something like
"\001 1 of 3 \002".<br />
<code>definition</code> is the call tip text. This can contain multiple lines separated by
'\n' (Line Feed, ASCII code 10) characters. Do not include '\r' (Carriage Return, ASCII
code 13), as this will most likely print as an empty box. '\t' (Tab, ASCII code 9) is
supported if you set a tabsize with
<code><a class="message" href="#SCI_CALLTIPUSESTYLE">SCI_CALLTIPUSESTYLE</a></code>.<br /></p>
<p><b id="SCI_CALLTIPCANCEL">SCI_CALLTIPCANCEL</b><br />
This message cancels any displayed call tip. Scintilla will also cancel call tips for you if
you use any keyboard commands that are not compatible with editing the argument list of a
function.</p>
<p><b id="SCI_CALLTIPACTIVE">SCI_CALLTIPACTIVE</b><br />
This returns 1 if a call tip is active and 0 if it is not active.</p>
<p><b id="SCI_CALLTIPPOSSTART">SCI_CALLTIPPOSSTART</b><br />
This message returns the value of the current position when <code>SCI_CALLTIPSHOW</code>
started to display the tip.</p>
<p><b id="SCI_CALLTIPSETHLT">SCI_CALLTIPSETHLT(int hlStart, int hlEnd)</b><br />
This sets the region of the call tips text to display in a highlighted style.
<code>hlStart</code> is the zero-based index into the string of the first character to
highlight and <code>hlEnd</code> is the index of the first character after the highlight.
<code>hlEnd</code> must be greater than <code>hlStart</code>; <code>hlEnd-hlStart</code> is the
number of characters to highlight. Highlights can extend over line ends if this is
required.</p>
<p>Unhighlighted text is drawn in a mid gray. Selected text is drawn in a dark blue. The
background is white. These can be changed with
<code>SCI_CALLTIPSETBACK</code>,
<code>SCI_CALLTIPSETFORE</code>, and
<code>SCI_CALLTIPSETFOREHLT</code>.
</p>
<p><b id="SCI_CALLTIPSETBACK">SCI_CALLTIPSETBACK(int colour)</b><br />
The background colour of call tips can be set with this message; the default colour is white.
It is not a good idea to set a dark colour as the background as the default colour for normal
calltip text is mid gray and the defaultcolour for highlighted text is dark blue. This also
sets the background colour of <code>STYLE_CALLTIP</code>.</p>
<p><b id="SCI_CALLTIPSETFORE">SCI_CALLTIPSETFORE(int colour)</b><br />
The colour of call tip text can be set with this message; the default colour is mid gray.
This also sets the foreground colour of <code>STYLE_CALLTIP</code>.</p>
<p><b id="SCI_CALLTIPSETFOREHLT">SCI_CALLTIPSETFOREHLT(int colour)</b><br />
The colour of highlighted call tip text can be set with this message; the default colour
is dark blue.</p>
<p><b id="SCI_CALLTIPUSESTYLE">SCI_CALLTIPUSESTYLE(int tabsize)</b><br />
This message changes the style used for call tips from <code>STYLE_DEFAULT</code> to
<code>STYLE_CALLTIP</code> and sets a tab size in screen pixels. If <code>tabsize</code> is
less than 1, Tab characters are not treated specially. Once this call has been used, the
call tip foreground and background colours are also taken from the style.</p>
<p><b id="SCI_CALLTIPSETPOSITION">SCI_CALLTIPSETPOSITION(bool above)</b><br />
By default the calltip is displayed below the text, setting above to <code>true</code>
(1) will display it above the text.</p>
<h2 id="KeyboardCommands">Keyboard commands</h2>
<p>To allow the container application to perform any of the actions available to the user with
keyboard, all the keyboard actions are messages. They do not take any parameters. These
commands are also used when redefining the key bindings with the <a class="message"

<p>The <code>SCI_*EXTEND</code> messages extend the selection.</p>
<p>The <code>SCI_*RECTEXTEND</code> messages extend the rectangular selection
(and convert regular selection to rectangular one, if any).</p>
<p>The <code>SCI_WORDPART*</code> commands are used to move between word segments marked by
capitalisation (aCamelCaseIdentifier) or underscores (an_under_bar_ident).</p>
<p>The <code>SCI_HOME*</code> commands move the caret to the start of the line, while the
<code>SCI_VCHOME*</code> commands move the caret to the first non-blank character of the line
(ie. just after the indentation) unless it is already there; in this case, it acts as SCI_HOME*.</p>
<p>The <code>SCI_[HOME|LINEEND]DISPLAY*</code> commands are used when in line wrap mode to
allow movement to the start or end of display lines as opposed to the normal
<code>SCI_[HOME|LINEEND]</code> commands which move to the start or end of document lines.</p>
<p>The <code>SCI_[[VC]HOME|LINEEND]WRAP*</code> commands are like their namesakes
<code>SCI_[[VC]HOME|LINEEND]*</code> except they behave differently when word-wrap is enabled:
They go first to the start / end of the display line, like <code>SCI_[HOME|LINEEND]DISPLAY*</code>,
but if the cursor is already at the point, it goes on to the start or end of the document line,
as appropriate for <code>SCI_[[VC]HOME|LINEEND]*</code>.
</p>
<p>The <code>SCI_SCROLLTO[START|END]</code> commands scroll the document to the start
or end without changing the selection. These commands match OS X platform conventions for the behaviour of the
<code>home</code> and <code>end</code> keys. Scintilla can be made to match OS X applications
by binding the <code>home</code> and <code>end</code> keys to these commands.
</p>
<h2 id="KeyBindings">Key bindings</h2>
<p>There is a default binding of keys to commands that is defined in the Scintilla source in
the file <code>KeyMap.cxx</code> by the constant <code>KeyMap::MapDefault[]</code>. This table
maps key definitions to <code>SCI_*</code> messages with no parameters (mostly the <a
class="jump" href="#KeyboardCommands">keyboard commands</a> discussed above, but any Scintilla
command that has no arguments can be mapped). You can change the mapping to suit your own
requirements.</p>

</code>
<p><b id="keyDefinition">keyDefinition</b><br />
A key definition contains the key code in the low 16-bits and the key modifiers in the high
16-bits. To combine <code>keyCode</code> and <code>keyMod</code> set:<br />
<br />
<code>keyDefinition = keyCode + (keyMod &lt;&lt; 16)</code></p>
<p>The key code is a visible or control character or a key from the <code>SCK_*</code>
enumeration, which contains:<br />
<code>SCK_ADD</code>, <code>SCK_BACK</code>, <code>SCK_DELETE</code>, <code>SCK_DIVIDE</code>,
<code>SCK_DOWN</code>, <code>SCK_END</code>, <code>SCK_ESCAPE</code>, <code>SCK_HOME</code>,
<code>SCK_INSERT</code>, <code>SCK_LEFT</code>, <code>SCK_MENU</code>, <code>SCK_NEXT</code> (Page Down),
<code>SCK_PRIOR</code> (Page Up), <code>SCK_RETURN</code>, <code>SCK_RIGHT</code>,
<code>SCK_RWIN</code>,
<code>SCK_SUBTRACT</code>, <code>SCK_TAB</code>, <code>SCK_UP</code>, and
<code>SCK_WIN</code>.</p>
<p>The modifiers are a combination of zero or more of <code>SCMOD_ALT</code>,
<code>SCMOD_CTRL</code>, <code>SCMOD_SHIFT</code>, and <code>SCMOD_META</code>.
On OS X, the Command key is mapped to <code>SCMOD_CTRL</code> and the Control key to
<code>SCMOD_META</code>.
If you are building a table, you might
want to use <code>SCMOD_NORM</code>, which has the value 0, to mean no modifiers.</p>
<p><b id="SCI_ASSIGNCMDKEY">SCI_ASSIGNCMDKEY(int <a class="jump"
href="#keyDefinition">keyDefinition</a>, int sciCommand)</b><br />
This assigns the given key definition to a Scintilla command identified by
<code>sciCommand</code>. <code>sciCommand</code> can be any <code>SCI_*</code> command that has
no arguments.</p>
<p><b id="SCI_CLEARCMDKEY">SCI_CLEARCMDKEY(int <a class="jump"
href="#keyDefinition">keyDefinition</a>)</b><br />
This makes the given key definition do nothing by assigning the action <code>SCI_NULL</code>
to it.</p>
<p><b id="SCI_CLEARALLCMDKEYS">SCI_CLEARALLCMDKEYS</b><br />
This command removes all keyboard command mapping by setting an empty mapping table.</p>
<p><b id="SCI_NULL">SCI_NULL</b><br />
The <code>SCI_NULL</code> does nothing and is the value assigned to keys that perform no
action. SCI_NULL ensures that keys do not propagate to the parent window as that may
cause focus to move. If you want the standard platform behaviour use the constant 0 instead.</p>
<h2 id="PopupEditMenu">Popup edit menu</h2>
<p><b id="SCI_USEPOPUP">SCI_USEPOPUP(bool bEnablePopup)</b><br />
Clicking the wrong button on the mouse pops up a short default editing menu. This may be
turned off with <code>SCI_USEPOPUP(0)</code>. If you turn it off, context menu commands (in
Windows, <code>WM_CONTEXTMENU</code>) will not be handled by Scintilla, so the parent of the
Scintilla window will have the opportunity to handle the message.</p>
<h2 id="MacroRecording">Macro recording</h2>
<p>Start and stop macro recording mode. In macro recording mode, actions are reported to the
container through <code><a class="message" href="#SCN_MACRORECORD">SCN_MACRORECORD</a></code>

record these actions for future replay.</p>

<h2 id="Printing">Printing</h2>
<p><code>SCI_FORMATRANGE</code> can be used to draw the text onto a display surface
which can include a printer display surface. Printed output shows text styling as on the
screen, but it hides all margins except a line number margin. All special marker effects are
removed and the selection and caret are hidden.</p>
<p>Different platforms use different display surface ID types to print on. On Windows, these are
<code>HDC</code>s., on GTK+ 3.x <code>cairo_t *</code>,
and on Cocoa <code>CGContextRef</code> is used.</p>

<p><b id="SCI_FORMATRANGE">SCI_FORMATRANGE(bool bDraw, Sci_RangeToFormat *pfr)</b><br />
This call renders a range of text into a device context. If you use
this for printing, you will probably want to arrange a page header and footer; Scintilla does
not do this for you. See <code>SciTEWin::Print()</code> in <code>SciTEWinDlg.cxx</code> for an
example. Each use of this message renders a range of text into a rectangular area and returns
the position in the document of the next character to print.</p>
<p><code>bDraw</code> controls if any output is done. Set this to false if you are paginating
(for example, if you use this with MFC you will need to paginate in
<code>OnBeginPrinting()</code> before you output each page.</p>
<pre>
struct Sci_Rectangle { int left; int top; int right; int bottom; };
struct Sci_RangeToFormat {
Sci_SurfaceID hdc; // The Surface ID we print to
Sci_SurfaceID hdcTarget; // The Surface ID we use for measuring (may be same as hdc)
Sci_Rectangle rc; // Rectangle in which to print
Sci_Rectangle rcPage; // Physically printable page size
Sci_CharacterRange chrg; // Range of characters to print
};
</pre>
<p>On Windows, <code>hdc</code> and <code>hdcTarget</code> should both be set to the device context handle
of the output device (usually a printer). If you print to a metafile these will not be the same
as Windows metafiles (unlike extended metafiles) do not implement the full API for returning
information. In this case, set <code>hdcTarget</code> to the screen DC.<br />
<code>rcPage</code> is the rectangle <code>{0, 0, maxX, maxY}</code> where <code>maxX+1</code>
and <code>maxY+1</code> are the number of physically printable pixels in x and y.<br />
<code>rc</code> is the rectangle to render the text in (which will, of course, fit within the
rectangle defined by rcPage).<br />
<code>chrg.cpMin</code> and <code>chrg.cpMax</code> define the start position and maximum
position of characters to output. All of each line within this character range is drawn.</p>
<p>On Cocoa, the surface IDs for printing (<code>bDraw=1</code>) should be the graphics port of the current context
(<code>(CGContextRef) [[NSGraphicsContext currentContext] graphicsPort]</code>) when the view's drawRect method is called.
The Surface IDs are not really used for measurement (<code>bDraw=0</code>) but can be set
to a bitmap context (created with <code>CGBitmapContextCreate</code>) to avoid runtime warnings.</p>
<p>On GTK+, the surface IDs to use can be found from the printing context with
<code>gtk_print_context_get_cairo_context(context)</code>.</p>
<code>chrg.cpMin</code> and <code>chrg.cpMax</code> define the start position and maximum
position of characters to output. All of each line within this character range is drawn.</p>
<p>When printing, the most tedious part is always working out what the margins should be to
allow for the non-printable area of the paper and printing a header and footer. If you look at
the printing code in SciTE, you will find that most of it is taken up with this. The loop that
causes Scintilla to render text is quite simple if you strip out all the margin, non-printable
area, header and footer code.</p>
<p><b id="SCI_SETPRINTMAGNIFICATION">SCI_SETPRINTMAGNIFICATION(int magnification)</b><br />
<b id="SCI_GETPRINTMAGNIFICATION">SCI_GETPRINTMAGNIFICATION</b><br />
<code>SCI_GETPRINTMAGNIFICATION</code> lets you to print at a different size than the screen
font. <code>magnification</code> is the number of points to add to the size of each screen
font. A value of -3 or -4 gives reasonably small print. You can get this value with
<code>SCI_GETPRINTMAGNIFICATION</code>.</p>
<p><b id="SCI_SETPRINTCOLOURMODE">SCI_SETPRINTCOLOURMODE(int mode)</b><br />
<b id="SCI_GETPRINTCOLOURMODE">SCI_GETPRINTCOLOURMODE</b><br />
These two messages set and get the method used to render coloured text on a printer that is
probably using white paper. It is especially important to consider the treatment of colour if
you use a dark or black screen background. Printing white on black uses up toner and ink very
many times faster than the other way around. You can set the mode to one of:</p>

<p><b id="SCI_SETPRINTWRAPMODE">SCI_SETPRINTWRAPMODE(int wrapMode)</b><br />
<b id="SCI_GETPRINTWRAPMODE">SCI_GETPRINTWRAPMODE</b><br />
These two functions get and set the printer wrap mode. <code>wrapMode</code> can be
set to <code>SC_WRAP_NONE</code> (0), <code>SC_WRAP_WORD</code> (1) or
<code>SC_WRAP_CHAR</code> (2). The default is
<code>SC_WRAP_WORD</code>, which wraps printed output so that all characters fit
into the print rectangle. If you set <code>SC_WRAP_NONE</code>, each line of text
generates one line of output and the line is truncated if it is too long to fit
into the print area.<br />
<code>SC_WRAP_WORD</code> tries to wrap only between words as indicated by
white space or style changes although if a word is longer than a line, it will be wrapped before
the line end. <code>SC_WRAP_CHAR</code> is preferred to
<code>SC_WRAP_WORD</code> for Asian languages where there is no white space
between words.</p>

<p>On Windows, the message-passing scheme used to communicate between the container and
Scintilla is mediated by the operating system <code>SendMessage</code> function and can lead to
bad performance when calling intensively. To avoid this overhead, Scintilla provides messages
that allow you to call the Scintilla message function directly. The code to do this in C/C++ is
of the form:</p>
<pre>
#include "Scintilla.h"
SciFnDirect pSciMsg = (SciFnDirect)SendMessage(hSciWnd, SCI_GETDIRECTFUNCTION, 0, 0);
sptr_t pSciWndData = (sptr_t)SendMessage(hSciWnd, SCI_GETDIRECTPOINTER, 0, 0);
// now a wrapper to call Scintilla directly
sptr_t CallScintilla(unsigned int iMessage, uptr_t wParam, sptr_t lParam){
return pSciMsg(pSciWndData, iMessage, wParam, lParam);
}
</pre>
<p><code>SciFnDirect</code>, <code>sptr_t</code> and <code>uptr_t</code> are declared in
<code>Scintilla.h</code>. <code>hSciWnd</code> is the window handle returned when you created
the Scintilla window.</p>
<p>While faster, this direct calling will cause problems if performed from a different thread
to the native thread of the Scintilla window in which case <code>SendMessage(hSciWnd, SCI_*,
wParam, lParam)</code> should be used to synchronize with the window's thread.</p>
<p>This feature also works on GTK+ but has no significant impact on speed.</p>
<p>From version 1.47 on Windows, Scintilla exports a function called
<code>Scintilla_DirectFunction</code> that can be used the same as the function returned by
<code>SCI_GETDIRECTFUNCTION</code>. This saves you the call to
<code>SCI_GETDIRECTFUNCTION</code> and the need to call Scintilla indirectly via the function
pointer.</p>
<p><b id="SCI_GETDIRECTFUNCTION">SCI_GETDIRECTFUNCTION</b><br />
This message returns the address of the function to call to handle Scintilla messages without
the overhead of passing through the Windows messaging system. You need only call this once,
regardless of the number of Scintilla windows you create.</p>
<p><b id="SCI_GETDIRECTPOINTER">SCI_GETDIRECTPOINTER</b><br />
This returns a pointer to data that identifies which Scintilla window is in use. You must call
this once for each Scintilla window you create. When you call the direct function, you must
pass in the direct pointer associated with the target window.</p>
<p><b id="SCI_GETCHARACTERPOINTER">SCI_GETCHARACTERPOINTER</b><br />
<b id="SCI_GETRANGEPOINTER">SCI_GETRANGEPOINTER(int position, int rangeLength)</b><br />
<b id="SCI_GETGAPPOSITION">SCI_GETGAPPOSITION</b><br />
Grant temporary direct read-only access to the memory used by Scintilla to store
the document.</p>
<p><code>SCI_GETCHARACTERPOINTER</code> moves the gap within Scintilla so that the
text of the document is stored consecutively
and ensure there is a NUL character after the text, then returns a pointer to the first character.
Applications may then pass this to a function that accepts a character pointer such as a regular
expression search or a parser. The pointer should <em>not</em> be written to as that may desynchronize
the internal state of Scintilla.</p>
<p>Since any action in Scintilla may change its internal state
this pointer becomes invalid after any call or by allowing user interface activity. The application
should reacquire the pointer after making any call to Scintilla or performing any user-interface calls such
as modifying a progress indicator.</p>
<p>This call takes similar time to inserting a character at the end of the document and this may
include moving the document contents. Specifically, all the characters after the document gap
are moved to before the gap. This compacted state should persist over calls and user interface
actions that do not change the document contents so reacquiring the pointer afterwards is very
quick. If this call is used to implement a global replace operation, then each replacement will
move the gap so if <code>SCI_GETCHARACTERPOINTER</code> is called after
each replacement then the operation will become O(n^2) rather than O(n). Instead, all
matches should be found and remembered, then all the replacements performed.</p>
<p><code>SCI_GETRANGEPOINTER</code> provides direct access to just the
range requested. The gap is not moved unless it is within the requested range so this call
can be faster than <code>SCI_GETCHARACTERPOINTER</code>.
This can be used by application code that is able to act on blocks of text or ranges of lines.</p>
<p><code>SCI_GETGAPPOSITION</code> returns the current gap position.
This is a hint that applications can use to avoid calling <code>SCI_GETRANGEPOINTER</code>
with a range that contains the gap and consequent costs of moving the gap.</p>
<h2 id="MultipleViews">Multiple views</h2>
<p>A Scintilla window and the document that it displays are separate entities. When you create
a new window, you also create a new, empty document. Each document has a reference count that
is initially set to 1. The document also has a list of the Scintilla windows that are linked to
it so when any window changes the document, all other windows in which it appears are notified
to cause them to update. The system is arranged in this way so that you can work with many
documents in a single Scintilla window and so you can display a single document in multiple
windows (for use with splitter windows).</p>
<p>Although these messages use <code>document *pDoc</code>, to ensure compatibility with future
releases of Scintilla you should treat <code>pDoc</code> as an opaque <code>void*</code>. That
is, you can use and store the pointer as described in this section but you should not
dereference it.</p>

</code>
<p><b id="SCI_GETDOCPOINTER">SCI_GETDOCPOINTER</b><br />
This returns a pointer to the document currently in use by the window. It has no other
effect.</p>
<p><b id="SCI_SETDOCPOINTER">SCI_SETDOCPOINTER(&lt;unused&gt;, document *pDoc)</b><br />
This message does the following:<br />
1. It removes the current window from the list held by the current document.<br />
2. It reduces the reference count of the current document by 1.<br />
3. If the reference count reaches 0, the document is deleted.<br />
4. <code>pDoc</code> is set as the new document for the window.<br />
5. If <code>pDoc</code> was 0, a new, empty document is created and attached to the
window.<br />
6. If <code>pDoc</code> was not 0, its reference count is increased by 1.</p>
<p><b id="SCI_CREATEDOCUMENT">SCI_CREATEDOCUMENT</b><br />
This message creates a new, empty document and returns a pointer to it. This document is not
selected into the editor and starts with a reference count of 1. This means that you have
ownership of it and must either reduce its reference count by 1 after using
<code>SCI_SETDOCPOINTER</code> so that the Scintilla window owns it or you must make sure that
you reduce the reference count by 1 with <code>SCI_RELEASEDOCUMENT</code> before you close the
application to avoid memory leaks.</p>
<p><b id="SCI_ADDREFDOCUMENT">SCI_ADDREFDOCUMENT(&lt;unused&gt;, document *pDoc)</b><br />
This increases the reference count of a document by 1. If you want to replace the current
document in the Scintilla window and take ownership of the current document, for example if you
are editing many documents in one window, do the following:<br />
1. Use <code>SCI_GETDOCPOINTER</code> to get a pointer to the document,
<code>pDoc</code>.<br />
2. Use <code>SCI_ADDREFDOCUMENT(0, pDoc)</code> to increment the reference count.<br />
3. Use <code>SCI_SETDOCPOINTER(0, pNewDoc)</code> to set a different document or
<code>SCI_SETDOCPOINTER(0, 0)</code> to set a new, empty document.</p>
<p><b id="SCI_RELEASEDOCUMENT">SCI_RELEASEDOCUMENT(&lt;unused&gt;, document *pDoc)</b><br />
This message reduces the reference count of the document identified by <code>pDoc</code>. pDoc
must be the result of <code>SCI_GETDOCPOINTER</code> or <code>SCI_CREATEDOCUMENT</code> and
must point at a document that still exists. If you call this on a document with a reference
count of 1 that is still attached to a Scintilla window, bad things will happen. To keep the
world spinning in its orbit you must balance each call to <code>SCI_CREATEDOCUMENT</code> or
<code>SCI_ADDREFDOCUMENT</code> with a call to <code>SCI_RELEASEDOCUMENT</code>.</p>
<h2 id="BackgroundLoadSave">Background loading and saving</h2>
<p>To ensure a responsive user interface, applications may decide to load and save documents using a separate thread
from the user interface.</p>
<h3 id="BackgroundLoad">Loading in the background</h2>
<p>An application can load all of a file into a buffer it allocates on a background thread and then add the data in that buffer
into a Scintilla document on the user interface thread. That technique uses extra memory to store a complete copy of the
file and also means that the time that Scintilla takes to perform initial line end discovery blocks the user interface.</p>
<p>To avoid these issues, a loader object may be created and used to load the file. The loader object supports the ILoader interface.</p>
<p><b id="SCI_CREATELOADER">SCI_CREATELOADER(int bytes)</b><br />
Create an object that supports the <code>ILoader</code> interface which can be used to load data and then
be turned into a Scintilla document object for attachment to a view object.
The <code>bytes</code> argument determines the initial memory allocation for the document as it is more efficient
to allocate once rather than rely on the buffer growing as data is added.
If <code>SCI_CREATELOADER</code> fails then 0 is returned.</p>

<p>The application should call the <code>AddData</code> method with each block of data read from the file.
<code>AddData</code> will return SC_STATUS_OK unless a failure, such as memory exhaustion occurs.
If a failure occurs in <code>AddData</code> or in a file reading call then loading can be abandoned and the loader released with
the <code>Release</code> call.
When the whole file has been read, the <code>ConvertToDocument</code> method should be called to produce a Scintilla
document pointer which can be used in the same way as a document pointer returned from
<a class="message" href="#SCI_CREATEDOCUMENT">SCI_CREATEDOCUMENT</a>.
There is no need to call <code>Release</code> after <code>ConvertToDocument</code>.</p>
<h3 id="BackgroundSave">Saving in the background</h2>
<p>An application that wants to save in the background should lock the document with <code>SCI_SETREADONLY(1)</code>
to prevent modifications and retrieve a pointer to the unified document contents with
<a class="message" href="#SCI_GETCHARACTERPOINTER">SCI_GETCHARACTERPOINTER</a></code>.
The buffer of a locked document will not move so the pointer is valid until the application calls <code>SCI_SETREADONLY(0)</code>.</p>
<p>If the user tries to performs a modification while the document is locked then a <code><a class="message"
href="#SCN_MODIFYATTEMPTRO">SCN_MODIFYATTEMPTRO</a></code> notification is sent to the application.
The application may then decide to ignore the modification or to terminate the background saving thread and reenable
modification before returning from the notification.</p>
<h2 id="Folding">Folding</h2>
<p>The fundamental operation in folding is making lines invisible or visible. Line visibility
is a property of the view rather than the document so each view may be displaying a different
set of lines. From the point of view of the user, lines are hidden and displayed using fold
points. Generally, the fold points of a document are based on the hierarchical structure of the
document contents. In Python, the hierarchy is determined by indentation and in C++ by brace
characters. This hierarchy can be represented within a Scintilla document object by attaching a
numeric "fold level" to each line. The fold level is most easily set by a lexer, but you can
also set it with messages.</p>
<p>It is up to your code to set the connection between user actions and folding and unfolding.
The best way to see how this is done is to search the SciTE source code for the messages used
in this section of the documentation and see how they are used. You will also need to use
markers and a folding margin to complete your folding implementation.
The <code>"fold"</code> property should be set to <code>"1"</code> with
<code>SCI_SETPROPERTY("fold", "1")</code> to enable folding. </p>

When some lines are hidden and/or annotations are displayed, then a particular line in the
document may be displayed at a
different position to its document position. If no lines are hidden and there are no annotations,
this message returns
<code>docLine</code>. Otherwise, this returns the display line (counting the very first visible
line as 0). The display line of an invisible line is the same as the previous visible line. The
display line number of the first line in the document is 0. If lines are hidden and
<code>docLine</code> is outside the range of lines in the document, the return value is -1.
Lines can occupy more than one display line if they wrap.</p>

corresponds to a display line (counting the display line of the first line in the document as

The first two messages mark a range of lines as visible or invisible and then redraw the
display.
<code>SCI_GETLINEVISIBLE</code> reports on the visible state of a line and returns 1 if it is
visible and 0 if it is not visible.
<code>SCI_GETALLLINESVISIBLE</code> returns 1 if all lines are visible and 0
if some lines are hidden.
These messages have no effect on fold levels or fold
flags. The first line can not be hidden.</p>
<p><b id="SCI_SETFOLDLEVEL">SCI_SETFOLDLEVEL(int line, int level)</b><br />
<b id="SCI_GETFOLDLEVEL">SCI_GETFOLDLEVEL(int line)</b><br />
These two messages set and get a 32-bit value that contains the fold level of a line and some
flags associated with folding. The fold level is a number in the range 0 to
<code>SC_FOLDLEVELNUMBERMASK</code> (4095). However, the initial fold level is set to
<code>SC_FOLDLEVELBASE</code> (1024) to allow unsigned arithmetic on folding levels. There are
two addition flag bits. <code>SC_FOLDLEVELWHITEFLAG</code> indicates that the line is blank and
allows it to be treated slightly different then its level may indicate. For example, blank
lines should generally not be fold points and will be considered part of the preceding section even though
they may have a lesser fold level.
<code>SC_FOLDLEVELHEADERFLAG</code> indicates that
the line is a header (fold point).</p>
<p>Use <code>SCI_GETFOLDLEVEL(line) &amp; SC_FOLDLEVELNUMBERMASK</code> to get the fold level
of a line. Likewise, use <code>SCI_GETFOLDLEVEL(line) &amp; SC_FOLDLEVEL*FLAG</code> to get the
state of the flags. To set the fold level you must or in the associated flags. For instance, to
set the level to <code>thisLevel</code> and mark a line as being a fold point use:
<code>SCI_SETFOLDLEVEL(line, thisLevel | SC_FOLDLEVELHEADERFLAG)</code>.</p>
If you use a lexer, you should not need to use <code>SCI_SETFOLDLEVEL</code> as this is far
better handled by the lexer. You will need to use <code>SCI_GETFOLDLEVEL</code> to decide how
to handle user folding requests. If you do change the fold levels, the folding margin will
update to match your changes.
<p><b id="SCI_SETFOLDFLAGS">SCI_SETFOLDFLAGS(int flags)</b><br />
In addition to showing markers in the folding margin, you can indicate folds to the user by
drawing lines in the text area. The lines are drawn in the foreground colour set for <a

<code>flags</code> determine where folding lines are drawn:<br />

This message searches for the next line after <code>startLine</code>, that has a folding level
that is less than or equal to <code>level</code> and then returns the previous line number. If
you set <code>level</code> to -1, <code>level</code> is set to the folding level of line
<code>startLine</code>. If <code>from</code> is a fold point, <code>SCI_GETLASTCHILD(from,
-1)</code> returns the last line that would be in made visible or hidden by toggling the fold
state.</p>
<p><b id="SCI_GETFOLDPARENT">SCI_GETFOLDPARENT(int startLine)</b><br />
This message returns the line number of the first line before <code>startLine</code> that is
marked as a fold point with <code>SC_FOLDLEVELHEADERFLAG</code> and has a fold level less than
the <code>startLine</code>. If no line is found, or if the header flags and fold levels are
inconsistent, the return value is -1.</p>
<p><b id="SCI_TOGGLEFOLD">SCI_TOGGLEFOLD(int line)</b><br />
Each fold point may be either expanded, displaying all its child lines, or contracted, hiding
all the child lines. This message toggles the folding state of the given line as long as it has
the <code>SC_FOLDLEVELHEADERFLAG</code> set. This message takes care of folding or expanding
all the lines that depend on the line. The display updates after this message.</p>
<p><b id="SCI_SETFOLDEXPANDED">SCI_SETFOLDEXPANDED(int line, bool expanded)</b><br />
<b id="SCI_GETFOLDEXPANDED">SCI_GETFOLDEXPANDED(int line)</b><br />
These messages set and get the expanded state of a single line. The set message has no effect
on the visible state of the line or any lines that depend on it. It does change the markers in
the folding margin. If you ask for the expansion state of a line that is outside the document,
the result is <code>false</code> (0).</p>
<p>If you just want to toggle the fold state of one line and handle all the lines that are
dependent on it, it is much easier to use <code>SCI_TOGGLEFOLD</code>. You would use the
<code>SCI_SETFOLDEXPANDED</code> message to process many folds without updating the display
until you had finished. See <code>SciTEBase::FoldAll()</code> and
<code>SciTEBase::Expand()</code> for examples of the use of these messages.</p>

These messages provide a higher-level approach to folding instead of setting expanded flags and showing

<p>An individual fold can be contracted/expanded/toggled with <code>SCI_FOLDLINE</code>.
To affect all child folds as well call <code>SCI_FOLDCHILDREN</code>.</p>
<p>To affect the entire document call <code>SCI_FOLDALL</code>. With <code>SC_FOLDACTION_TOGGLE</code>
the first fold header in the document is examined to decide whether to expand or contract.

This is used to respond to a change to a line causing its fold level or whether it is a header to change,
perhaps when adding or removing a '{'.</p>

Instead of implementing all the logic for handling folding in the container, Scintilla can provide behaviour
that is adequate for many applications. The <code>automaticFold</code> argument is a bit set defining
which of the 3 pieces of folding implementation should be enabled. Most applications should be able to use the
<code>SC_AUTOMATICFOLD_SHOW</code> and <code>SC_AUTOMATICFOLD_CHANGE</code>
flags unless they wish to implement quite different behavious such as defining their own fold structure.
<code>SC_AUTOMATICFOLD_CLICK</code> is more likely to be set off when an application would
like to add or change click behaviour such as showing method headers only when Shift+Alt is used in
conjunction with a click.

This is useful when saving the user's folding when switching documents or saving folding with a file.
The search starts at line number <code>lineStart</code> and continues forwards to the end of the file.

<p>By default, Scintilla does not wrap lines of text. If you enable line wrapping, lines wider
than the window width are continued on the following lines. Lines are broken after space or tab
characters or between runs of different styles. If this is not possible because a word in one
style is wider than the window then the break occurs after the last character that completely
fits on the line. The horizontal scroll bar does not appear when wrap mode is on.</p>
<p>For wrapped lines Scintilla can draw visual flags (little arrows) at end of a a subline of a
wrapped line and at begin of the next subline. These can be enabled individually, but if Scintilla
draws the visual flag at the beginning of the next subline this subline will be indented by one char.
Independent from drawing a visual flag at the begin the subline can have an indention.</p>
<p>Much of the time used by Scintilla is spent on laying out and drawing text. The same text
layout calculations may be performed many times even when the data used in these calculations
does not change. To avoid these unnecessary calculations in some circumstances, the line layout
cache can store the results of the calculations. The cache is invalidated whenever the
underlying data, such as the contents or styling of the document changes. Caching the layout of
the whole document has the most effect, making dynamic line wrap as much as 20 times faster but
this requires 7 times the memory required by the document contents plus around 80 bytes per
line.</p>
<p>Wrapping is not performed immediately there is a change but is delayed until the display
is redrawn. This delay improves peformance by allowing a set of changes to be performed
and then wrapped and displayed once. Because of this, some operations may not occur as
expected. If a file is read and the scroll position moved to a particular line in the text,
such as occurs when a container tries to restore a previous editing session, then
the scroll position will have been determined before wrapping so an unexpected range
of text will be displayed. To scroll to the position correctly, delay the scroll until the
wrapping has been performed by waiting for an initial
<a class="message" href="#SCN_PAINTED">SCN_PAINTED</a> notification.</p>
