Important! The usage of this scrolling canvas is that one creates  widgets onto the canvas, rather than managing them as children. In particular, if you're trying to
frame $canvas.subframe ...rather than
$canvas add rectangle ...you're headed for trouble.MG Aug 21 2007 - Does anyone have a minimal example of a scrollable canvas meant for containing other widgets? I'm trying to put a frame inside a canvas to scroll it, but my lack of canvas-use in the past is coming back to haunt me, and I can't find any good, small examples of how to do it...MG, a few minutes later Discovered what the problem I was having was, oddly enough on the canvas page - my widgets weren't children of the canvas, and so stuck out over it. Making all the widgets displayed on the canvas children of it solved the problem (thanks DKF!).
