The QSequentialAnimationGroup class provides a sequential group of animations.
QSequentialAnimationGroup is a QAnimationGroup that runs its animations in sequence, i.e., it starts one animation after another has finished playing. The animations are played in the order they are added to the group (using addAnimation() or insertAnimation()). The animation group finishes when its last animation has finished.
At each moment there is at most one animation that is active in the group; it is returned by currentAnimation(). An empty group has no current animation.
A sequential animation group can be treated as any other animation, i.e., it can be started, stopped, and added to other groups. You can also call addPause() or insertPause() to add a pause to a sequential animation group.
QSequentialAnimationGroup *group = new QSequentialAnimationGroup; group->addAnimation(anim1); group->addAnimation(anim2); group->start();
In this example, anim1 and anim2 are two already set up QPropertyAnimations.

Returns the animation in the current time.
Access functions:
| QAbstractAnimation * | currentAnimation() const |
Notifier signal:
| void | currentAnimationChanged(QAbstractAnimation *current) |
Constructs a QSequentialAnimationGroup. parent is passed to QObject's constructor.
[virtual] QSequentialAnimationGroup::~QSequentialAnimationGroup()Destroys the animation group. It will also destroy all its animations.
Adds a pause of msecs to this animation group. The pause is considered as a special type of animation, thus animationCount will be increased by one.
See also insertPause() and QAnimationGroup::addAnimation().
[signal] void QSequentialAnimationGroup::currentAnimationChanged(QAbstractAnimation *current)QSequentialAnimationGroup emits this signal when currentAnimation has been changed. current is the current animation.
Note: Notifier signal for property currentAnimation.
See also currentAnimation().

[override virtual protected] bool QSequentialAnimationGroup::event(QEvent *event)Reimplemented from QAnimationGroup::event().
Inserts a pause of msecs milliseconds at index in this animation group.
