The above was the missing piece of the puzzle for me thank you much. Now
another question: 

Those same "command=self.function" buttons do something I don't
understand:

I have a button whose command argument reads "command=self.Add" This
works as I would expect. But, if I want to pass arguments to the
function as in "command=self.Add(a,b,c)"

I see the following behaviour: The script executes the function when it
is run, NOT when the button is pushed, and actually pushing the button
does nothing.

How does one pass arguments to a callback function?

Thanks.
