Author Scrollbar implementation in Canvas, Panda 8.4

Greetings everyone,

Does anyone know how to implement scrollbars in Panda:Canvas?
Here's part of the codes that we're working on.

aCanvas:= Canvas new.
aCanvas drawAction:
[:aGraphicsContext |
aGraphicsContext translateBy: 250 @ 200.
adRect := aCanvas bounds.
interface drawing display: adRect with: aGraphicsContext].
aCanvas allScrollbars: true.

We tried to use the above method, allScrollbars: but it seems to crash
everytime when we try to load the GUI. Would there be other method or
example of inserting scrollbars in canvas usable for our cause?

Well, Canvas doesn't support scrollbars. If you want to somehow scroll your
canvas, put it in a Form and use its scrollbars.

And So It Goes
