Embedded window in wxPython app

[Richard Townsend]

I've been experimenting with passing a window handle from a wxPython app to
a Tkinter app. The Tkinter app should embed a Toplevel window containing a
Canvas widget in the wxPython app's Frame (see example below).

Both apps run, but the Tkinter app's output doesn't appear.

Can anyone see why this isn't working?

Using wxPython-2.5.1/Python 2.3.3/Win98 and Win2000.
