-\class QAnimationState
-
-\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}.
-
-\code
-QStateMachine machine;
-QAnimationState *s = new QAnimationState(machine->rootState());
-QPropertyAnimation *animation = new QPropertyAnimation(obj, "pos");
-s->setAnimation(animation);
-QState *s2 = new QState(machine->rootState());
-s->addTransition(s, SIGNAL(animationFinished()), s2);
-machine.start();
