public class FlipTransition extends Transition

A Transitions that flips between 2 components/forms using perspective transform where available.

Notice that this looks rather different on devices as perspective transform is available there but isn't on the simulator.

    Transition
    copy(boolean reverse)
    Create a copy of the transition, usually the transition used is a copy.
    int
    getBgColor()
    The background color that is painted behind the flipping effect or -1 to use the paintBackgrounds method instead
    int
    getDuration()
    The duration for the flip transition
    void
    initTransition()
    Callback thats invoked before a transition begins, the source form may be null for the first form in the application.
