I believe there is in fact support for this in Lion's table view. See, for example, the NSTableView class reference for a description of the 'NSTableViewAnimationEffectGap' constant. I'd also recommend you watch the 2011 WWDC video on this topic. IIRC there was a demo of this particular animation, and if you're lucky there will be some sample code in the slides that you can plunder. _______________________________________________ Cocoa-dev mailing list ([email protected]) Please do not post admin requests or moderator comments to the list.
