Re: [wxlua-users] recursive calls runbuffer

[klaas.holwerda <ng...@kl...>]

Hi John,

Indeed if out commented, it works okay again.
So recursive calls is not the problem it seems, only the assert.
Don't know if the m_is_running is very important, but if yes or just handy to have, i think the 
up/down counter would deal with the situation.

Regards,

Klaas

I honestly don't know. Did you try to call wxSTC::AddTextRaw(const char*)?
This function does not do any UTF8 conversions before passing the string to
Scintilla.

I've added it to the controls sample so you can see what events are emitted
and when, but this is all the code it takes to get a browser window.

f = wx.wxFrame(wx.NULL, -1, "wxWebView!")
w = wxwebview.wxWebView.New(f, -1, "http://wxlua.sourceforge.net")

This is the GetValue() function, there's not much you can do with the void*

[wxlua-users] Fwd: How to create wxTreeEvent

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

Hi John,

I'm trying to create wxTreeEvent and ran into unexpected difficulties.

I've tried the following (item_id is wxTreeItemId I got from event:GetItem()):

1. wx.wxTreeEvent(wx.wxEVT_COMMAND_TREE_ITEM_ACTIVATED, item_id)

got an error saying that the second parameter is a userdata, but needs
to be a number

2. Tried to get id from wxTreeItemId, but it doesn't have GetID() even
though the documentation references it
(http://docs.wxwidgets.org/trunk/classwx_tree_item_id.html).

3.     local treeevent = wx.wxTreeEvent(wx.wxEVT_COMMAND_TREE_ITEM_ACTIVATED)
treeevent:SetClientObject(tree:GetItemData(item_id))

got an error saying that wxTreeEvent doesn't have SetClientObject.

How do I construct ITEM_ACTIVATED event for a particular item? Thank you.

Paul.

[wxlua-users] recursive calls runbuffer

[klaas.holwerda <ng...@kl...>]

Hi,

Recursive calls to RunBuffer() is a problem, gives an assert.

int wxLuaState::RunBuffer(const char buf[], size_t size, const wxString &name, int nresults)
{
     wxCHECK_MSG(Ok(), LUA_ERRRUN, wxT("Invalid wxLuaState"));
     wxCHECK_MSG(!M_WXLSTATEDATA->m_wxlStateData->m_is_running, LUA_ERRRUN, wxT("Lua interpreter is 
already running"));

Maybe a solution could be to make m_running an integer, which is incremented and decremented, as 
long as > 1, interpreter is running.
But maybe it should be done different, still I would like to use the same wxlua state.

Recursive happens in lua scripts which define functions to be used inside canvas objects, and are 
run there using:

         wxLuaState lst = a2dLuaWP->GetLuaState();
         lua_State* L = lst.GetLuaState();
         if ( 0 != lst.RunString( m_script ) )

The function is defined like this in the wxLua script.

     TheObjectAddScript_2 =
     [[
         function XoverX( canobj, x, y, args )
             fill = wx.a2dFill( args.Colour )

             local childs = canobj:CreateChildObjectList()
             canobjcirc2 = wx.a2dCircle( 0, 0, 20 )
             childs:push_back( canobjcirc2 )
             for i = -args.maxX, args.maxX do
                 local y2
                 if  i ~= 0  then
                     y2 = -args.maxY*math.sin(i/16)/(i/16)
                 else
                     y2 = -args.maxY; --sin(x)/x goes to one at zero
                 end
                 -- all relative
                 line = wx.a2dRect( i, 0, 0.1, y2 )
                 line:SetFill( fill )
                 childs:push_back( line )
             end
         end
     ]]

-- add the object using the above string as input script
canobjAddScript2 = wx.a2dCanvasObjectLua( 350, -450, TheObjectAddScript_2, "XoverX"  )

How are you running it? You need to run the app as a "bundle" meaning that
you either double click the bundle dir (usually ProgramName.app) or run
this on the command line.

Using gdb if I remember correctly. I don't have a working Mac right now,
but I believe that XCode comes with the command line gcc compiler tools and

 Sure could use some help.

The wxWidgets install looked to go smoothly with no errors in the log. BUT,
when I tried to run /samples/widgets, nothing happens, and the terminal
goes unresponsive.

I am following the directions here:
http://wxlua.sourceforge.net/docs/install.html , installed in it's own

How would I debug this?

I don't know what logs to look at. The system.log is giving me this for

Mar 11 14:04:54 Roys-MacBook-Pro.local firefox[393]: CGSCopyDisplayUUID:

Hi John,

> Yes, note that From8BitData() is static and To8BitData() is not.

Thank you for the prompt change! Unfortunately, it didn't have the
desired effect for me; maybe I misread wxwidgets documentation.

Let's say I have three invalid UTF-8 characters: string.char(0x80,
0x81, 0x82). If I assigned them to a variable u, it has proper length
(#u == 3). If I try to add them to wxSTC, nothing happens (the length
of the content doesn't change).

If I use From8BitData(), then I get 6 bytes instead of 3:
#wx.wxString.From8BitData(string.char(0x80, 0x81, 0x82)) == 6, but
this looks like "fixed" UTF-8 code. When I add the result to wxSTC, I
do get 6 bytes of content there, but that's not what I expected: I
expected three characters displayed with 0x80, 0x81, and 0x82 as their
codes.

What am I doing wrong?

I don't know the first thing about creating a wxLua binding, but if 
nobody else is already working on it or wants to, I'll see if I can find 
some time.  I primarily desire to hook up wxWebViewChromium 
(https://github.com/steve-lamerton/wxWebViewChromium) in my wxLua

As a small sampling for information's sake, in looking at a fairly 
complete sample of how I use wxPropertyGrid in C++ code, I touch:

* wxPropertyGridManager
* wxPropertyGridPage
* wxPropertyGridEvent
* wxPGId
* wxPGProperty
* wxEVT_PG_CHANGED, wxEVT_PG_SELECTED, wxEVT_PG_RIGHT_CLICK, 
wxEVT_COMMAND_TEXT_UPDATED, wxEVT_COMMAND_BUTTON_CLICKED, wxEVT_CHILD_FOCUS
* wxPGRegisterEditorClass with 
wxPropertyGridManager::SetPropertyEditor() and derived wxPGEditor and 
wxPGProperty classes

Thanks for your help!

Admittedly, most people need only a tiny part of it. I remember that there
was something funny about it though, something about #defines and pointers
that seemed like wrapping it might be awkward, but looking now I don't see
why I thought that.

I didn't realize we don't have wxWebView binding. I'm very much

Hi John,

Not really, as you can simply skip all invalied 8-bit characters
(which is what I do to "fix" invalid sequences). Scintilla does better
as it can display them as well.

> From8BitData() is now in SVN trunk. I'm not sure that it will help as it uses the wxConvISO8859_1 converter, but it is different than the normal wxConvUTF8 converted used normally.

Do we also get To8BitData(), as I may need it to save the data back to a file?

I'll compile and give it a test some time tomorrow... Thank you!

I'm no expert in UTF8, but isn't it possible that a malformed UTF8 sequence
makes the rest of the file unusable in the sense that you can't really be
sure how many bytes the 'bad' sequence is so you could be off by a few
bytes for the rest of the file?

From8BitData() is now in SVN trunk. I'm not sure that it will help as it
uses the wxConvISO8859_1 converter, but it is different than the normal
wxConvUTF8 converted used normally.

[wxlua-users] How to make invalid UTF-8 data to appear in wxSTC in Unicode builds?

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

Hi John,

I'm looking for a way to handle (possibly) invalid UTF-8 characters
and seem to be missing wxString::From8BitData() and
wxString::To8BitData() methods (according to this page:
http://docs.wxwidgets.org/trunk/overview_unicode.html#overview_unicode_supportout).

What I am trying to do is to load a file into wxSTC (Scintilla
component). I know that Scintilla can deal with invalid UTF-8
characters as SciTE displays them as nice inverted rounded boxes with
hex codes inside, but I can't get the same effect with wxSTC. If I try
to load UTF-8 file with characters in, for example, 1252 encoding, the
content fails to load into wxSTC (it shows as empty).

You can see this effect by running editor.wx.lua example. Just try to
load a file that has \232 or \226 character and the content is going
to be empty.

What's interesting is that the content is loaded from a file just
fine, so it seems like at least that part is handled correctly, but
the text is not loaded into wxSTC until I find and fix invalid UTF-8
characters (I use SetText method, but I've tried others with the same
result). I thought that using From8BitData() may help me to pass all
those characters intact to Scintilla, which will be able to display
them, but I can't test as From8BitData() is not exposed in wxlua.

I'm open to other ideas to make it work...

Paul.
