answer 1: the "scale" method modifies the item coordinates
|
|
only. since bitmaps, images, windows, and text strings have
|
|
a single coordinate pair, they can only move around, not
|
|
change size...
|
|
|
|
answer 2: resizing images and fonts on the fly is a non-trivial
|
|
problem, especially if you want both performance and port-
|
|
ability. so Tk simply passes on this one...
|
|
|
|
in other words, you're on your own. it can be done,
|
|
but it takes some work...
