Normally MVC applies within one application with one event loop. So you set up your GUI and then start the event loop. The GUI will process user events (e.g. typing text, pressing buttons, selecting menus) as callbacks that do things like create Controller objects and execute methods on them. So for starters your Controller object should not create root nor should it call mainloop to start the event loop. Those two actions should be done once by the main script that launches your application. As to where to go from here...it would help to know more about what you are trying to do. -- Russell -- http://mail.python.org/mailman/listinfo/python-list
