Can I point you here: http://www.cocoabuilder.com/archive/message/cocoa/2008/2/23/199705Thank you very much for this link. You provide there a very clever solution, but, as you aptly put in your posting: "It uses NSTreeNode and -representedObject, so is 10.5 only." But alas!, I need Tiger 10.4.11. (And am reluctant to use private methods which you hint at in your psoting).Kind regards, Gerriet.
Ah, sorry about that, I didn't realise. What you can do is have a look at
http://www.wilshipley.com/blog/2006/04/pimp-my-code-part-10-whining-about.htmlWil gives a few category methods like -objectAtIndexPath: You can (maybe) get the index path the _NSArrayControllerTreeNode and then get your real object, in which you have an isExpanded flag.
