API

- (CALayer *)prepareForAnimation;

Call this method in order to obtain the layer with current window contents. You would use this layer to animate things, i.e. run CAAnimations on top of it.

- (void)completeAnimationAndOrderFront:(BOOL)shouldOrderFront;

Call when you are done animating your window. BOOL argument determines if window should be dismissed or presented (for dismissing and presenting animations).

@property (nonatomic, assign) BOOL livePreview;

By setting this to YES, your layer will look alive, updating it's contents during animation. This may be performance-expensive, but sometimes this is required to make good animation. Window won't respond to clicks, but key event still will be processes (so you'll see the changes in text fields, etc.)

How does it work?

When you want to animate the whole NSWindow, you call prepareForAnimationWithInsets:. This method will hide the receiver and create a proxy window which will contain receiver's screenshot wrapped into CALayer that will be returned back to you. You can do whatever you want with that layer. When you finished, just call completeAnimationAndOrderFront: to remove proxy window from screen.

Please refer to the headers for additional documentation.
