Thread: Re: [Pythoncard-users] Added MDI support to Pythoncard (was MDI - childwindows within a window)

I am happy to report that I've succeeded in Pythoncardize 
the wx.SashLayoutWindow control of wxPython 
 using similar technique to the MDI support I reported previously.   Not sure if 
the screen capture attachment to this email will get stripped or not.  If you 
don't see the screen shot, shout and I'll try to upload that somewhere.
