Thanks!

On a related topic, it seems like it would be nice to do *all* drawing
in
response to paint events. When I get an event from the timer, I would
just tell wx that part of the window needs redrawing, and depend on it
to give me a paint even when nothing of higher priority needs to be
done.
I've seen this kind of logic recommended in other GUI tookits. Is it a
good idea in wxPython, and, if so, how does one do it?
