[Tkinter-discuss] Minimizing a Python/Tk application

[Metz, Bobby W, WWCS]

Yes, manipulating Tk from a child thread is problematic and can't be
done directly, e.g. try launching a Dialog box from a thread and see
what happens.  One trick I've done in the past is to pass a reference to
the parent to the child thread, then when I want to update the GUI in
the parent, say a status message line, I simple set the variable behind
it using the parent reference.  If you're going to have multiple threads
updating that could get tricky I suppose considering the variable
locking, but I'm sure someone out here has done it.

Anyone?

Thanks Francois,

Multiple threads are always trickier. On the other hand, wxpython could
be
the solution, but I wish it could be done in Tk, because I already have
the multiplatform program written and it would save me redoing it just
for
Windows. And also see my previous message.
