Python GUI wrapper for a long operation

[Stewart Midwinter]

good stuff!

I'll study your app for some clues for my own situation. I want to
continually get data from a remote server, and then graph values that
I have received, probably using Tkinter canvas widget.  Understanding
threads will be helpful for me, so I'll study how you used threads in
your app.

You may want to post your idea on the tkinter mailing list, 
thanks,
