Some time ago I published sample code illustrating how to implement a Source List view that mimicked the Source List displays found in iTunes and the Finder. I was surprised to discover how widely my sample code was linked to by others.
With the release of Leopard, Apple has added the ability to build Source List displays directly into NSTableView/NSOutlineView. I have updated my sample code to take advantage of the changes Apple has made. This reduces the amount of work I have to do and allows the sample code to adopt any cosmetic changes Apple may introduce in the future.
