Please explain in detail what the "other module" is doing. And as
written this class "app" looks pretty useless to me. Why subclass Tk
(well it appears you "tried" to subclass it anyway) just to override
capabilities that are already available within Tk?

Also i see many mistakes in this very small code sample. Using my
deductive logic leads me to believe that many mistakes in a small code
sample translates to enormous mistakes in a larger code base. So feel
free to ramble incessantly about the intricate workings of this jewel
of Python scripting you are soon to drop on this malnourished group of
coders.
