This is the main reason I stick to Tkinter. I've never seen any widget just half
as powerful as tk's canvas in any other GUI toolkit.

BTW, does anybody know any of these toolkits that have a decent equivalent of 
tk's canvas? There are quite a lot of GUI toolkits interfaced with Python 
(wxWindows, GTK, Qt, FLTK, Fox, ...) and I never had time to experiment them all 
to see how easily a vector-graphics drawing application can be done. If anybody 
has any experience with that, I'd be glad to hear about it.
