NSOutlineView Source List Section Headers

I'm using a view-based NSOutlineView to create a source list. The NSOutlineView is connected to a Data Source and Delegate object.

However, I can't seem to find what I need to implement in order to utilize the section headers (e.g., "LIBRARY", "STORE", "DEVICES", etc. in iTunes). What methods do I need to implement in the Data Source/Delegate to achieve this?

Solution

  • IIRC you just need to implement NSOutlineViewDelegate's outlineView:isGroupItem:.
