I have a big document view. On it I place some small subviews. I f I

scrollbar, it should stick there.
is there a sane way of achieving this or do I better lock for an
other behavior?
It's fairly easy to do. Register to receive bounds-changed
notifications from your document view's clip view -- what the
documentation calls the scroll view's content view, actually the
parent view of your document view -- and also tell the clip view to
post these notifications, since it doesn't do that by default.
When you receive the notification, you can use the document view's
visibleRect (which is the clip view bounds, but in the document view's
bounds coordinate system) to work out whether and where to move the
subview.
