Quick PyGTK Tip

If you ever find yourself writing a custom widget using PyGTK, and can’t figure out why none of your do_something methods are ever getting called, make sure you have this line of code after your class’s definition:

gobject.type_register (YourCustomWidgetClass)

Believe me, remembering this will save you at least an hour of very confused debugging. PyGTK will never complain that you forgot to do this. Instead, you’ll just end up with a widget that doesn’t actually do anything.
