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.
