Simple class to monitor the user-visible portion of an NSScrollView document view.


An NSScroller subclass that makes it possible to determine the overlay style's slot thickness and detect changes to it.


A class that can be used to observe the scroller overlay size and visibily changes. This makes use of some heuristics that aren't perfect, but the end result is quite good. Must be used in combination with ObservableScroller, but does not enforce an NSScrollView subclass requirement.


A very simple NSScrollView subclass that will always use overlay style scrollers, regardless of user prefs or input device types.


A class that works around a pretty esoteric problem:

The scroll-position jumping will occur if this view contains an NSTextView and:

  • non-contiguous layout enabled for the NSTextView's NSLayoutManager
  • there are actual non contiguous blocks in the layout
  • the NSTextView is configured so text does not wrap to the view's bounds
  • there are at least some lines of text that are actually larger than the view's bounds
  • the containing NSScrollView has a vertical ruler present
  • the pointing device is a trackpad
