I exactly use a ScrollBar. Here is a code excerpt:
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
| window pane |
window := SystemWindow labelled: 'Mondrian Canvas'.
window model: self.
window extent: 640 @ 480.
pane := ScrollPane new.
canvas := MOCanvas on: self root.
pane scroller addMorph: canvas.
window
addMorph: pane
frame: (0 @ 0 corner: 1 @ 1).
window openInWorld.
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
MOCanvas is a subclass of Morph that is resized on some point.
Apparently, this incantation does not activate this clipping.
