PXSourceList

PXSourceList is an NSOutlineView subclass used for easily implementing source lists in your applications.

Using a source list for navigation is a common user interface paradigm in OS X applications, but requires a fair amount of manual set up and customisation of standard Cocoa controls.

PXSourceList subclasses NSOutlineView and provides much of the common styling and idiomatic behaviour of source lists for you through a clean and simple API.
