I'm pretty sure the OP is talking specifically about scrolling with the scroll wheel. (It sounds like the individual table views in his view collection don't have scroll bars, and are sized to show all their content anyway.) In that case, the table views or scroll views are still responding the scroll wheel, which prevents the collection view itself from scrolling. I think the only way to fix this is to override the appropriate 'scrollWheel:' event method, and to pass the event on up the responder chain. NSScrollView's documentation lists that method, so presumably that's the appropriate method, and so it would be necessary to subclass NSScrollView, override 'scrollWheel:' and figure out a way of bypassing the NSScrollView implementation (since the usual '[super scrollWheel:]' technique won't achieve that here). I guess you'd have to walk the responder chain manually (not normally recommended), or find the NSScrollView's superclass's implementation via the 'objc_...' runtime routines (not normally recommended), although maybe there's a simpler way that's just not occurring to me right now. _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
