I'm stuck on a weird bug with NSTableViews and CALayers. I tried to ask up at WWDC in one of the labs, but didn't get an answer.
I have a auto-resizing NSTableView subclass in NSScrollView in a layer backed view. I'm using the 10.6 SDK and targeting 10.5 as well. When I resize, the contents "jump" in the table view. I believe it is because there's an implicit animation to move the bounds and/or position. Or maybe something in the clip? I'd also not like it to fade in if I toggle between layer-backed and not. I've searched on the mailing lists, StackOverflow, and Google in general for this, but I haven't found a solution. I've tried the following but without any change to the behavior: 1. Custom NSScrollView and NSTableView, each of which implement what I believe should disable animations: - (id<CAAction>)actionForLayer:(CALayer *)layer forKey:(NSString *)key { return (id<CAAction>)[NSNull null]; } I also tried returning nil as well. 2. Setting the actions (position, bounds, frame, hidden, onOrderIn) on the layers to NSNull. 3. Bracketing live resize methods with a CATransaction to disable animations. The results were not pretty. I have a small sample project available: <http://nekotech.com/Code/Splitter.zip> Oddly enough, when the view is small and the scroll bar is present, the "jumping" doesn't occur. Thoughts and suggestions welcomed!
