wxlua-users Mailing List for wxLua

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.

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" )

Hi,
The internal FindwxWidgets.cmake, should also contains lines like:
 wxbase31${_UCD}${_DBG}
else it does not work for current wxWidgets svn.
But even if that produces projects files with Cmake, it does not build, there are compile errors.
But for 3.0 it works.
Regards,
Klaas

Awesome. Can you add your sample to the wxLua distribution for easy out 
of box testing?
Thanks!

My antique mac is out of commission so I can't do any mac stuff right now,
but I do plan to replace the hard drive drive..

I added wxWebView support a while ago, but forgot to press send on my
email. Let me know if it works for you. I just did the simplest test of
creating a frame, a webview child and loaded a page.

Do you have plans to include these methods? I'm building the current
version of wxwidgets and would like to include these Mac* methods and
WebView support if available. Thank you!

Hi John,
I'd like to come back to this topic; maybe it's something I'm doing
wrong and it's still possible to process those invalid UTF-8
characters? Any ideas?
Paul.

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.
$ open /path/to/Program.app

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
gdb is the debugger for it.

Don't know about this; do you sometimes use two monitors and the settings
are stale or something?

 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
directory as OSX, debug, unicode build.
How would I debug this?
I don't know what logs to look at. The system.log is giving me this for
what it is worth:
Mar 11 14:04:54 Roys-MacBook-Pro.local Console[394]: CGSCopyDisplayUUID:
Invalid display 0x1a493041
Mar 11 14:04:54 Roys-MacBook-Pro.local firefox[393]: CGSCopyDisplayUUID:
Invalid display 0x1a493041
I am a PC based web programmer (PHP, MySql, JQuery, a little Python) diving
in and learning OSX, terminal and Lua/wxLua, wanting to move into mobile
development.
