I'm using minItemSize but I think they have the same problems. I'm not sure how I'd get the same behaviour without using it. You can observe the behaviour I want at with the beta of my program (http://www.maven.de/code/wowplot/ , some example data is at http://www.maven.de/code/wowplot/ extract.txt ). The relevant bit is the stretch and shrink timeline entries in the view menu, which in- or decrease the effective size of the NSCollectionView x-axis. —Jens Thanks, Daniel. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

I'm having exactly the same problems, and have unfortunately not found any work-arounds so far. I have reported these as rdar://5962073 NSCollectionView resizes its item-views incorrectly rdar://5950467 NSCollectionView does not work correctly with NSScrollView's autohideScrollers rdar://5962086 NSCollectionView scrolls to origin on resize As for the "jump to first row problem" (i.e. 5962086), I don't think it's the NSCollectionView per-se doing the scrolling, at least it is never sent a scrollTo: message, so it must be something else (some strange interaction with the NSScrollView and the animation?). I quite like the collection view, but it needs better documentation (i.e. an NSCollectionView Programming Guide) and quite a few bug-fixes.

NSCollectionView problems
Hello List, I have an NSCollectionView set up with bindings to visualize an NSMutableArray. When I call arrayController:setContent: the view (which initially doesn't have a content assigned) displays the items. So far so good. The problems are these: If there are two many items for one page to display, the vertical scroller appears. However, it's not the correct size. It's displayed as if all items would fit into the view (all but an imaginary 10 pixel row). It doesn't get the correct size until after the view is resized. Is there some way to force the view to recalculate it's scroll bar sizes? Or could this be caused by how the content is assigned (I'm using an array controller)? The second problem is when the view is resized (due to window resizing or any other reason). When the collection view is scrolled down with some item in the middle of the collection selected (so the scrollbar is not on it's topmost position), the resize causes the collection display to jump to the first item row. This problem can be observed in the Apple supplied IconCollection demo. Is there a way to prevent that? Thanks for any input! I'm using Xcode 3.0 on 10.5.2 Regards Markus -- __ Markus Spoettl smime.p7s Description: S/MIME cryptographic signature ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
