At the very least, you aren’t doing what the scroll(rect:by:)) method
description tells you to do:
developer.apple.com/reference/appkit/nsview/1483497-scroll
<http://developer.apple.com/reference/appkit/nsview/1483497-scroll>
You also need to change the view’s origin to reflect the scroll, and you need
to use one of the “needsDisplay” methods to indicate the area(s) invalidated by
the scroll.
Is there anything to discuss about why you “cannot use” NSScrollView? The
existing functionality would make life a lot easier for you.
