No problem, but please do file an enhancement request (http://bugreport.apple.com) so that this becomes part of the standard NSOutlineView API. It's one of the few (if not the only) things lacking in a full source list implementation. It'll probably be marked as a duplicate, but the engineers can best gauge the demand for a feature by how many enhancement requests are filed against it. --Kyle Sluder ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Hiding the disclosure triangle of a specific group item in a bound NSOutlineView
Hi List, I have an NSOutlineView based source list bound to a tree controller and I can't figure out how to create a group item that does not have a disclosure triangle - as an example, the MAILBOXES folder group in Mail.app does that. I thought it might be possible by returning NO for the - shouldCollapseItem: and -shouldExpandItem: delegate methods for the group item in question but that doesn't do have that effect. It makes the item non-expandable/non-collapsable but it still shows its disclosure triangle. I also set the datasource (the outline is bound) and implemented the datasource method - (BOOL)outlineView:(NSOutlineView *)outlineView isItemExpandable: (id)item but that never gets called. Any ideas on how to make the disclosure triangle disappear for a specific item? Is this only possible in data source driven outline views?
