[squeak-dev] Morphic, Balloon, Scrollbar

Dear All,

I know some of you are morphic expert :-)
I am still on the quest to make Mondrian usuable in Squeak. The
situation is the following: I have a window having scrollbar, and I am
trying to render (using Balloon) on a canvas bigger than what the window
can actually display. Balloon seems to not be aware of the part of the
canvas being actually displayed. It simply try to render everything.
Is my guess right? Can anyone confirm please?
Is there a way to turn this on?

Cheers,
Alexandre

Set the canvas's clip rectangle to the visible portion of your window
(clipBy:during:).
