Re: [wxlua-users] GetLineVisible always returns true?

Hi John,

> This is how I do it in stedit.cpp in the modules/wxstedit/src dir.

Should have checked there; I came up with very similar code, but also
included DocLineFromVisible:

function isLineVisible(line)
  local firstline = editor:DocLineFromVisible(editor:GetFirstVisibleLine())
  local lastline = math.min(editor:GetLineCount(),
    editor:DocLineFromVisible(editor:GetFirstVisibleLine() +
editor:LinesOnScreen()))
  return line >= firstline and line <= lastline
end

This is needed because lines can be wrapped (as they are in my case),
but LinesOnScreen counts those as well (so the number on the screen
will be larger than the number in the document).

Yes. It doesn't have the clearest name. I think you know this, but the
wxStyledTextCtrl function names map pretty closely to Scintilla's
message names.

http://www.scintilla.org/ScintillaDoc.html#SCI_GETLINEVISIBLE


This is how I do it in stedit.cpp in the modules/wxstedit/src dir.

    int first_line    = top_line < 0 ? GetFirstVisibleLine() : top_line;
    int line_count    = GetLineCount();
    int lines_visible = LinesOnScreen();
    int last_line     = bottom_line < 0 ? wxMin(line_count, first_line
+ lines_visible) : bottom_line;

[Paul K <pau...@ya...>]

In the best tradition of self-answering, it turned out that
GetLineVisible doesn't do what I need: it only checks against whether
the line is hidden because of folding (not if it's outside of the
visible area, which is what I'm looking for). I don't see any other
API method that does this, so I calculate it myself using
GetFirstVisibleLine, LinesOnScreen, and DocLineFromVisible.

[wxlua-users] GetLineVisible always returns true?

[Paul K <pau...@ya...>]

Hi John,

Thank you for adding wxAuiToolBar to wxlua. One short question on
GetLineVisible. According to the documentation it should return "1 if
the passed in line is visible or 0 if it is not". For some reason, no
matter what I pass, I always get back "true". Is it possible that
there is some bug in the conversion of numbers wxlua gets from
wxwidgets/Scintilla? Thank you.

I tried to compile 2.9.5 using the latest code from SVN (including
your last fix), but it still fails with a similar issue:

[ 47%] Building CXX object
modules/wxbind/CMakeFiles/wxLuaBindLib.dir/src/wxadv_bind.cpp.obj

D:/Lua/build/wxWidgets-2.9.5/include/wx/generic/grid.h:216:18: note:

This includes your fix in rev #158. I'd prefer not to stub and, but
rather compile out of the box. Also, it seems like the fix is likely
to break in the next update of wxwidgets:

!%wxchkver_2_9_5 virtual void PaintBackground(const wxRect& rectCell,
wxGridCellAttr *attr );
%wxchkver_2_9_5  virtual void PaintBackground(const wxRect& rectCell,
const wxGridCellAttr &attr );

Is it possible to do "<" and ">=" instead of "!" and (implied) "=="? Thank you.

Re: [wxlua-users] Multiple views for wxSTC in wxlua

Hi John,

I also looked at wxSTEditor::RefEditor (src/stedit.cpp) that has
similar logic, but it didn't shed any light on why what I am doing
below is not working.

> local docpointer = e1:GetDocPointer()
> e2:AddRefDocument(docpointer) --<-- crashes here

It actually crashes whether I use e1 or e2 to add a reference.
Similarly, using SetDocPointer crashes too. This is all using wxlua
2.8.12 with wxwidgets 2.8.12 on windows. Any hint on how to make it
work would be appreciated.

Re: [wxlua-users] Multiple views for wxSTC in wxlua

[Paul K <pau...@ya...>]

Hi John,

It still crashes right on AddRefDocument:

require "wx"
local frame = wx.wxFrame(wx.NULL, wx.wxID_ANY, "STC Demo",
  wx.wxDefaultPosition, wx.wxSize(450, 450), wx.wxDEFAULT_FRAME_STYLE )
local e1 = wxstc.wxStyledTextCtrl(frame, wx.wxID_ANY,
  wx.wxDefaultPosition, wx.wxSize(0, 0), wx.wxBORDER_STATIC)
local e2 = wxstc.wxStyledTextCtrl(frame, wx.wxID_ANY,
  wx.wxDefaultPosition, wx.wxSize(0, 0), wx.wxBORDER_STATIC)
local sizer = wx.wxBoxSizer(wx.wxVERTICAL)
sizer:Add(e1, 1, wx.wxEXPAND + wx.wxALL, 10)
sizer:Add(e2, 1, wx.wxEXPAND + wx.wxALL, 10)
frame:SetAutoLayout(true)
frame:SetSizer(sizer)

local docpointer = e1:GetDocPointer()
e2:AddRefDocument(docpointer) --<-- crashes here

frame:Show(true)
wx.wxGetApp():MainLoop()

What am I doing wrong? I just need a simple example that shows two STC
windows with the same document. Thank you.

Paul.

Humm... this is probably a problem with the scintilla editor's lexer.
I will take a look, but I thinking fixing this may have to be done
with the wxWidget's code itself.

You need to increase the ref count of the doc pointer.

AddRefDocument(origEditor->GetDocPointer());
SetDocPointer(origEditor->GetDocPointer());

and then release it before the refed editor is destroyed.

ReleaseDocument(GetDocPointer());

Hope this helps,

[wxlua-users] strange editor.wx.lua behaviour 2.9.4

[Victor B. <so...@te...>]

Hello,

this only happens with wx.lua linked against wxwidgets 2.9.4 (not 2.8.12)

to reproduce strange behaviour 

1- open editor.wx.lua
2- create a text of several lines surrounded by --[[ and ]]--
3- change betwen --[[ and ---[[

strange behaviour: lines only get colour updated when you position the cursor on that line.

I also had other strange behaviour about updating deleted lines but I dont have reproducing sequence.

[wxlua-users] Multiple views for wxSTC in wxlua

[Paul K <pau...@ya...>]

Hi All,

Does anyone have an example of how multiple views can be used in
wxlua? I looked at the documentation here
http://www.yellowbrain.com/stc/mult_views.html, but even a simple code
like this crashes the app:

local pointer = ed:GetDocPointer()
ed:ReleasePointer(pointer)

I tried several other combinations that I thought would work, but all
cause app crashes with the same error (c000005).

Is there a working combination that allows me to have two views of the
same document? I'm running on Windows using wxlua 2.8.12.x and
wxwidgets 2.8.12.

Paul.

No... not so much a work in progress as continual work of mapping the
functions. Since wxLua wraps so much of wxWidgets any change in their
API anywhere causes breakage.

I will fix this tomorrow, but note that if you don't intend to call
that particular function you can just rem out the failing part in the
C++ binding code and put in whatever minimal stub is needed to get it
to compile.

Don't add the child panel's sizers since the child panels already manage them.

>  panelSizer:Add(paneltopSizer,1,wx.wxGROW)
>  panelSizer:Add(panelbottomSizer,1,wx.wxGROW)

Add the child panels themselves and the panelSizer will check if the
child panels have sizers of their own to perform the layout.

 panelSizer:Add(paneltop,1,wx.wxGROW)
 panelSizer:Add(panelbottom,1,wx.wxGROW)

This was tough to find, but by remming out parts I was able to find
where the code that caused the crash came from.

It's been about 15 years since I've done anything in C, never touched C++ - but 
I think I figured out the original issue.

----
    wxImageHistogram::iterator * self = (wxImageHistogram::iterator 
*)wxluaT_getuserdatatype(L, 1, wxluatype_wxImageHistogram_iterator);
    // call op_inc
    wxImageHistogram::iterator* returns = &((*self)++);
    // push the result datatype
    wxluaT_pushuserdatatype(L, returns, wxluatype_wxImageHistogram_iterator);

----

If I gather this correctly, you're trying to post increment that iterator, if 
this were a normal pointer it would work -

But I'm guessing the iterator type has an operator overload for the ++ operator, 
ultimately calling a function, so (*self)++ is just a function call, the result 
of which is being casted to an pointer.

the compiler is complaining that it has to "throw away" the intermediate value, 
to give you a pointer, and is refusing to do so.

The fix....
----

    wxImageHistogram::iterator * self = (wxImageHistogram::iterator 
*)wxluaT_getuserdatatype(L, 1, wxluatype_wxImageHistogram_iterator);
    // call op_inc
    wxImageHistogram::iterator returns = (*self)++;
    // push the result datatype
    wxluaT_pushuserdatatype(L, &returns, wxluatype_wxImageHistogram_iterator);

----

grab the actual result from the iterator override, and then cast as a pointer 
for the "lua_push"

phew.... I don't really miss this stuff at all ;)

Here's hoping this is correct!

Re: [wxlua-users] Popup menu leaking resources

Sorry for a very long delay (I was buried under work...)

I guess I might be using an old version of wxLua, but I cannot use
delete on the menu?

I get an error like
wxLua: Unable to call wxuserdata:delete() on object!
Function called 'delete(userdata)'
01. wxMenu::delete(wxMenu(self))

(the above was written in I hope I did not make a typo during it)

The above happened when I tried menu:delete()

menu:Delete is something which deletes parts from a menu, so it does
not really help.

I managed to improve my situation a lot by making parts of my menu
structure reusable, it does not get rid of the leak completely, but it
decreases it by an order of magnitude.

I will be doing wxLua update, when I have some more time.
