not everything -- destroy releases all the Tk specific
stuff, but the proxy object hangs around until you've
removed all references to it.
(since Python objects don't know who's referring to
them, they cannot destroy all references by them-
in your case, assuming that "theWindow" is a global
variable, you can use:
theWindow = None
to get rid of it (assuming SolveThis doesn't create
a circual reference, that is).
if the code is local scope (inside a function or a
method), the variable will be deleted by Python
when you leave that scope.
