Hi, Basically your data model needs to be defined. It depends on your 'problem area'. It is usually good practice to keep your datamodel free of GUI elements, so that it can be easily reused. The GUI in the other hand can know everything about the public interface of the data model.
I've recently started to use pyDispatcher / wx.lib.pubsub to send messages from the object model to the GUI, notifying about additions / updates so that the individual elements such as the list control showing the items, or other views are updated without you having to make sure any little data change has to be synced with the GUI. The data syncs the GUI through an abstract interface. Python is a really good language for this .. Regards, - Jorgen -- http://mail.python.org/mailman/listinfo/python-list
