for pure Tkinter, I recommend using bind classes to implement "controllers"
on the canvas level, using appropriate find functions to locate the individual
items, and dispatching via "trackers".  see

for some background (I guess it's time to write that "later article" I mention
in that article.  if you cannot wait, feel free to steal the controller code from
the WCK).
