Well, I made a little demo project containing an NSOutlineView, cell-based with two text cell/columns, connected data source to app delegate, and in there implemented data source methods to supply 1000 items to the root.
Result: Behaves lazily as desired. Initially, it asks for about 100 more items than are visible, and whenever scrolling causes the headroom to get below 100 items, it asks for a bunch more; if you scroll very slowly, about one window’s worth. So I need to dig in and find what is different in my real project that makes NSOutlineView so proactive :( Jerry _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
