Interesting. Some variation of this might suit me, but I think one other
problem I'm having is that the ShowModal() method returns whenever a
button is pressed, so even if OK is pressed with an empty string in the
box, the dialog disappears and returns an "OK" value. I'll have to check
in the wxpython group on how to handle this one, I think.
