Mailing List Archive: TKinter modal dialog

Okay, here's the brief:

File processing task (adds structure to VRML files according to
heuristic rules determined by the user) needs to query the user every
so often if there is a missing/ambiguous rule. I would like to make
this a GUI dialogue using TKinter. I have said dialogue written using
the simpledialog class, and have looked at
http://www.pythonware.com/fredrik/tkdraft/ which suggests I might use
widget.wait_window, however, this doesn't really get the effect I'm
looking for, as it returns control to a widget, whereas I just want
the dialog to exit (and be destroyed) and control to return to the
processing run.

The win32 extension dialogs have a "doModal", which is exactly what
I'm looking for. Anyone care to point out what section of the docs I
didn't read that describes a TKinter doModal :) .

Enjoy,
Mike

I'm using a subclass of Toplevel to do this. However the window will
appear in the Windows Task Bar.
