You need to experiment with the parameters till you find a combination that gives the visual effect you expect. IIRC, the documentation is a little confusing because it leads you to believe that specifying a new frame rect is orthogonal to the fade. In fact, I seem to recall, specifying a frame rect indicates that you want the view to be visible at that size and position, and thus conflicts with the fade, producing the kind of inconsistent behavior you're seeing. Try leaving that key out of the dictionary. The problem, again IIRC, is that only the alpha can change smoothly, not the "isHidden" property, which can only be on or off. The "isHidden" property isn't being animated, just changed at certain points in the animation. You've asked for it to be both on and off at the end of the animation, and one of those wins. Remember also that NSViewAnimation is a subclass of NSAnimation, so you should be able to use a delegate (for example) to do what you want at the end of the animation. _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
