hi people.
when i create a widget, such as a toplevel window, and then i destroy
it, how can i test that it has been destroyed? the problem is that even
after it has been destroyed, the instance still exists and has a tkinter
name, so testing for None is not feasible:
>>> import Tkinter
>>> fin = None
>>> fin1 = Tkinter.Toplevel()
>>> fin1.destroy()
>>> print fin1

The winfo_exists method is what you want:
print fin1.winfo_exists()
0
However, I'm curious about *why* you want to do that: since *you* made the call
to destroy, what would you want to do anything with a widget you've already
destroyed?
