Okay, now I think I get what you're after. Let's simplify and clarify things. Let me know if I'm misinterpreting. 1) You have a container class that can instantiate objects of a thing class 2a) You wish for the container to be aware of all things it has created - OR - 2b) You wish for the Thing to be aware of all containers that have created them 3) You want this to happen automatically. I'm not sure which way round you're trying to do this, so I'll try to answer both. Your Container (Hooman) can construct multiple Things (Button), and other classes could also construct Things. So you need some way to automatically register the Thing as you create it. The easiest way to do this would, I think, be to have your Container subclass a utility class, and then use self.Button() instead of Button(). That can take care of registering the button in some sort of list, and then it can still return the button in case you need it for something else. Would that work? Or am I completely off on my analysis? ChrisA -- https://mail.python.org/mailman/listinfo/python-list
