Introduction

ScrollToRefresh is a subclass of NSScrollView that adds a "pull-to-refresh" feel to the "elastic" area of NSScrollview.

How it works

The secret is actually knowing how scroll views work. When you scroll, the clip view offsets the origin of its -bounds so any subview within the clipview will scroll. It also employs a couple of other methods to check the boundaries of the document view which I override to include the refresh view to get a more natural feel.
