Detailed Description

The QAnimationDriver class is used to exchange the mechanism that drives animations.

The default animation system is driven by a timer that fires at regular intervals. In some scenarios, it is better to drive the animation based on other synchronization mechanisms, such as the vertical refresh rate of the screen.

Warning
This function is not part of the public interface.
