Tk question: How can I tell, via code, if a button is actually being
displayed on the screen?

Say buttons are being created based on data from a configuration file.
 If I have a method that reads the config file and generates buttons,
how can I make sure those buttons are actually going to be displayed
on the screen?

I just ran into this problem when I forgot to 'pack' some buttons,
where 'packing' in Tk makes them visible/active on the screen.  But I
don't know how to test for that.
