| You are in luck, I have only recently wrestled with the same problem =
with scrolling an FXCanvas (not an FXGLCanvas - should be the same, =
though). This is how I finally got it to work, after many gruelling =
trials. Hope it is helpful. Not sure if it is the *correct* way =
though...

| # Make it fill up the space in its frame each time we resize.
| @scrollWindow.connect(SEL_CONFIGURE) {
|   frameThickness =3D 2 # Otherwise scrollbars cover frame.
|   @scrollWindow.resize @scrollWindow.parent.width - frameThickness,
|         @scrollWindow.parent.height - frameThickness

| I know my version works OK, so if this 'cut and paste' code doesn't =
then hassle me again.

the solution looks fairly simple, if you look at it afterwards, but
there are many holes to fall into on the way there ;)
