\brief The QAnimationState class provides state that handle an animation and emit

a signal when this animation is finished.

\ingroup statemachine

QAnimationState provides a state that handle an animation. It will start this animation
|
|
when the state is entered and stop it when it is leaved. When the animation has finished the
|
|
state emit animationFinished signal.
|
|
QAnimationState is part of \l{The State Machine Framework}.

QStateMachine machine;
