-
- # self.master.protocol("WM_DELETE_WINDOW", my_delete_callback)
-
- # unfortunately, some window managers will not send this request to a window.
- # the "protocol" function seems incapable of trapping these "aggressive" window kills.
- # this line of code catches everything, tho. The window is deleted, but you have a chance
- # of cleaning up first.
