Using Perl/Tk I've defined a horizontally Scrolled('Canvas', ...) whose -height I would like to change dynamically. I've tried:

1) configure(-height ...) on the scrolled widget,
2) configure(-height ...) on the 'canvas' subwidget,
3) re-packing the widget after configure,
4) re-packing the Frame that contains the widget.

Nothing seems to work: the widget remains at the originally-defined height, even though cget(-height) always returns the desired new value. I'm not a newcomer to Tk, but I've never run into a problem so intransigent. I must be overlooking something really stupid. Any ideas?
