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...
--------------------
@scrollWindow =3D FXScrollWindow.new aFrame, 0,
    LAYOUT_FIX_WIDTH|LAYOUT_FIX_HEIGHT

# 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
}

canvasFrame =3D FXHorizontalFrame @scrollWindow

canvas =3D FXCanvas.new canvasFrame, messageTarget, 0,
  LAYOUT_FIX_WIDTH|LAYOUT_FIX_HEIGHT,
  0, 0, 5000, 5000
-------------------

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