Cleaning Up an Application When the Window is Closed

[W. Watson]

Suppose I write some Win XP application using the Tkinter GUI, and do not
provide a mechanism to exit other than the user clicking on the X in the
upper right corner of a window. Is there a mechanism that will allow me to
put up an save-dialog to give the user the option to save his present state
of data?

You just need to catch the close event, which appears to be
"WM_DELETE_WIND OW" in Tkinter. The following article details its usage
near the bottom of the page under the heading "Protocols" :

http://www.pythonware.com/library/tkinter/introduction/events-and-bindings.htm

It actually mentions your problem specifically. I've never done it as
I usually use wxPython.
