No, because it eagerly creates a view for every item in the collection. So if you have a spreadsheet with 100,000 cells, it’s going to create 100,000 NSViews when the window opens. NSMatrix may work better because it uses only a single view, but IIRC it still preallocates an NSCell for every item. Also I think it’s been deprecated. I suspect you’ll need a custom view that uses cells or some other lightweight-view design pattern to avoid consuming resources for items that aren’t currently visible. (Of course, someone else may have already implemented that custom view, either as open source or commercially.) —Jens _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
