I am bewildered by Tk -- in general, but also with this specific problem:
But since I want to be able to deal with cases where there are too many widgets for the window to even fit the screen, I use a Pane object (so make the if(0) an if(1)), I have a new problem: the window starts too small. Sure, I can resize it manually. But how do I make its initial size be the right size, if possible?
Tk is making me sad!
