That's a good question, all right. I'm restarting in Python something I'd
originally started in perl with Perl/TK. In my perl original my code was
pretty unstructured, and in redoing I decided to modularize (which Python
makes a lot easier!). Without going into my whole possibly misbegotten
concept, my original idea for modules seemed to require knowing the text
size. Probably a better design will let me do the text, then the box as
you suggest. Sometimes I get hung up on a certain problem (in this case,
getting the text size before drawing it) and can't seem to move on until I
have a solution.
Thanks for the good information about TkFont module, and the point sized
And for the question "why?"
