Tkinter maintains its own widget hierarchy, and widgets don't go away unless you explicitly destroy them (by calling "destroy" on a widget or a widget parent), so you don't really need to keep references to them. however, if you need to access a widget later on, it might be a good idea to save a reference to it somewhere... </F> -- http://mail.python.org/mailman/listinfo/python-list
