Added in CVS.
-- get some sort of bitmap for testing
b = wx.wxArtProvider.GetBitmap(wx.wxART_NEW, wx.wxART_TOOLBAR)
-- make new art provider and return above bitmap for everything
a = wx.wxLuaArtProvider()
a.CreateBitmap = function(self, id, client, size)
return b
end
wx.wxArtProvider.Push(a)

Remember that if you create a new wxBitmap for each call to
CreateBitmap(...) that you .delete() it if you are not using it
elsewhere so they don't build up. You can very quickly run out of GDI
resources in MSW (even XP).
The problem is how to conveniently do this? You could use a single
global variable like below.
Note: The wxArtProvider caches the bitmaps itself so you do not need
to keep a copy in Lua.
single_global_art_bmp = nil
a.CreateBitmap = function(self, id, client, size)
if (single_global_art_bmp) then single_global_art_bmp.delete() end
create new single_global_art_bmp...
return single_global_art_bmp
end

John
