Hi,
you can animate a NSSplitView easily to achieve this effect. I use the
following code to animate the resize of a split view after the users
clicks a button:
- (IBAction)toggleSplitDisplay:(id)sender
{
NSSize newSize = [detailSplit frame].size;
[NSAnimationContext beginGrouping];
[[NSAnimationContext currentContext] setDuration:.5];
if ([sender selectedSegment] == 1) {
[[theLowerSubView animator] setFrameSize:newSize];
newSize.height = 2;
[[theUpperSubView animator] setFrameSize:newSize];
}
else if ([sender selectedSegment] == 0) {
[[theUpperSubView animator] setFrameSize:newSize];
newSize.height = 0;
[[theLowerSubView animator] setFrameSize:newSize];
}
[NSAnimationContext endGrouping];
}
Hope that helps, please contact me, if you need more information!

I've been looking for a while now how to replicate a widget like
Mail.app's "Mail Activity" slide-up/slide-down panel (the animation,
not the widget itself).
The several times I've tried NSViewAnimation, it seemed to be a non-
starter.
The bits and pieces that I've worked with CoreAnimation seem
promising, but it *feels* like there's something obvious that I'm
missing in terms of replicating the slide-up panel. You can see that
sliding panel widget in many Apple apps, like Mail, iTunes (album
cover), iPhoto's info panel, and Automator's workflow log, workflow
variables table, and Automator's Description View.
Again, I'm just trying to replicate the animation--if anyone has any
ideas, that would be really great.
