An NSOutlineView which is binded to a NSTreeController gives
instances of NSTreeControllerTreeNode in the item (or items) parameter
of their datasource or delegate methods. For example:
- (BOOL)outlineView:(NSOutlineView *)outlineView writeItems:(NSArray
*)items toPasteboard:(NSPasteboard *)pboard
would give an array of NSTreeControllerTreeNode objects in the items
parameter.
- (BOOL)outlineView:(NSOutlineView *)sender isGroupItem:(id)item
would give an instance of a NSTreeControllerTreeNode
As far as I know, this class is not documented. How can I access (or
know) the actual object in the NSTreeController that the item is
refering to.
I will appreciate any help.
