Actually, I gave you a partially wrong answer. I noticed you are using a NSOutlineView, but then I forgot to take into account the list hierarchy. In general, trying to back a hierarchical list with a flat array isn't going to work too well. The only time it really works is if the list never changes, in which case the correlation between row number and item is fixed. For the general case, you're going to need either a hierarchical data model, or the ability in your data source methods to construct the hierarchy on the fly. Either is feasible. NSTreeNode is a useful class if you're creating a hierarchical data model. _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
