You are absolutely correct. I've just confused with my tryouts.
Initially i've got a problem with this async code:
dialog = wx.wxDialog(wx.NULL, wx.wxID_ANY, "",wx.wxDefaultPosition,
wx.wxDefaultSize)
dialog:Connect(wx.wxEVT_END_PROCESS, function(event)
wx.wxMessageBox("EVENT HAPPEND")
end)
capt = wx.wxProcess(dialog)
capt:Redirect()
proc = wx.wxExecute([[cscript /nologo long.js 4095]],wx.wxEXEC_ASYNC,capt)
wx.wxGetApp():MainLoop()
My javascript code puts some 'a' letters :
WSH.Echo(Array(Number(WScript.arguments(0))+1).join("a"))
And with arguments bigger then 4095 i've got no MessageBox.

It looks like you're hitting the MS Windows cmd limitation.
"On computers running Microsoft Windows XP or later, the maximum length of
the string that you can use at the command prompt is 8191 characters. On
computers running Microsoft Windows 2000 or Windows NT 4.0, the maximum
length of the string that you can use at the command prompt is 2047
characters."

This code snippets doesn't work for me with cmd output bigger or equal 8180
symbols.
proc = wx.wxProcess()
proc:Redirect()
exec = wx.wxExecute("cmd /c echo "..string.rep("8",8180),true,proc)
output = proc:GetInputStream()
print(output:Read(100))
I'm trying wxlua 2.8.12.3 (ansi) with lua 5.1 and wxlua 2.8.12.3 (unicode)
with lua 5.2
operating system: WIndows 7 x64.
Why this happens?

Hi John,
A follow-up question on wxAuiTabArt. The class provides ShowDropDown
method that displays the list of opened tabs, but I'd like to replace
it with something else.
Is there a way to overwrite ShowDropDown method with my own? Thank you.
Paul.

Hi John,
I tried to compile the latest wxlua with the latest wxwidgets and ran
into a compilation error:
...wxlua/wxLua/modules/wxbind/src/wxstc_bind.cpp: In function
'wxLuaBindNumber* wxLuaGetDefineList_wxstc(size_t&)':
...wxlua/wxLua/modules/wxbind/src/wxstc_bind.cpp:13493:50: error:
'wxSTC_COFFEESCRIPT_HASHQUOTEDSTRING' was not declared in this scope
 { "wxSTC_COFFEESCRIPT_HASHQUOTEDSTRING",
wxSTC_COFFEESCRIPT_HASHQUOTEDSTRING },
 ^
make[2]: *** [modules/luamodule/CMakeFiles/wxLuaModule.dir/__/wxbind/src/wxstc_bind.cpp.obj]
Error 1
make[1]: *** [modules/luamodule/CMakeFiles/wxLuaModule.dir/all] Error 2
make: *** [all] Error 2
The latest wxwidgets (3.1) includes updated Scintilla component
(3.3.9), which appears to no longer have
wxSTC_COFFEESCRIPT_HASHQUOTEDSTRING.
Could you please remove the reference from the binding? I was able to
compile successfully after commenting it out. Thank you.
Paul.

Hi John,
I just noticed that wxAuiTabArt class is missing SetColour and
SetActiveColour methods for some reason. All the others (according to
the documentation at
http://docs.wxwidgets.org/trunk/classwx_aui_tab_art.html) appear to be
present.
Would it be possible to add these as well as it should allow to change
the color of tabs and the tab background for the notebook? Thank you!
Paul.

Looks good. Thank you for adding them back.

Ok, I made the change to increment an int as you suggested. Now
m_is_running is just informational.

Hi John,

It worked! I wasn't aware of *TextRaw methods and they do exactly
what's needed in this case. The only issue is that you don't provide
GetTextRaw, so I can show the file, but can't save proper results (as
they get mangled into a "fixed" UTF-8 when I use GetText()).
I only see AddTextRaw and InsertTextRaw in wxlua; there seems to be
GetTextRaw, SetTextRaw, AppendTextRaw, and GetSelectedTextRaw missing
from wxlua. Would it be possible to add them? Thank you!
Paul.

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.

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.

Hi John,

It was to trigger wxEVT_COMMAND_TREE_ITEM_ACTIVATED event manually:
wx.wxTreeEvent(wx.wxEVT_COMMAND_TREE_ITEM_ACTIVATED, item_id).

Thank you!

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")
f:Show()

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

If you rem these out does it work normally? I think I added the check so
people wouldn't forget that it was running, but there probably is any
reason why it wouldn't work.
