You probably want to use the Observer pattern. A simplified Pythonic
version would be something like
def addCallback(self, cb):
self._callbacks.append(cb)
...
def notify(self, *args, **kw):
for cb in self._callbacks:
cb(self, *args, **kw)
You can find a lot fancier variants (e.g. publish/subscribe) of this on the
web.
You can also create your own gobject signals or watch for changes in gobject
properties.
