Re: Need Help Creating an OutlineView for TabView selection

I would like to use an NSOutlineView to drive my preferences for selecting the tabs. I am having some trouble creating my datasource for this. I have attached a code attempt that used CFXMLTree, that worked except for I ended up with a root node that only had a subnode, which isn't what I really wanted. I want it to look more like

NSOutlineView asks the DataSource for the number of items and the actual items by sending nil. In your datasource, you should create an array of root items, which you return when item is nil.

I've never actually done this, though, so can't give you much more information than that - I just came across this information on the CocoaDev wiki. There's no mechanism in NSOutlineView tell it not to display the root node AFAIK. A better idea might be a subclass of NSOutlineView that doesn't display the root node, but rather uses all the level 1 nodes as "root".?
