I forgot to mention: you should not connect these methods
(do_expose_event() and do_realize()) to any signal, they are "virtual
methods" called automatically by PyGTK.

I got the idea partially from
http://ralph-glass.homepage.t-online.de/clock/clock.py and from
interpreting the example clock widget C code.
