Re: Preferred methods for usig NSOutlineView

We set the main window controller as both delegate and data source for the outline view. shouldSelectItem in the delegate handles clicks. For right clicks, we had to add code in the view. It was pretty straightforward. Apple has a sample project, but it's outdated and not very useful. Casey Mc
