That looks correct to me. The only other thing I'd add is that if the 
application is using a window, it should subclass KParts.MainWindow as the 
main window, and not KMainWindow (which is a base class to 
KParts.MainWindow).

I'll try to verify all of this in the next day or two, and add an example to 
PyKDE. The original example broke going from KDE2->3 and I never replaced it.
