Hello George,

thank you for this information.

This is a pity.

The background:
I want to create a code completition for an editor component.
It should distinguish between inherited and non inherited members.
Reason is, that on wxPython, most classes are derived from wxWindow.
For example if I want Code completition for wx.Frame, 
I always get the 200 or so suggestions,
whereby most times, I'm only interested in the possible completions of
wx.Frame and maybe wx.TopLevelWindow.
