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 QAnimationGroup::addAnimation() or QAnimationGroup::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.
In this example, anim1
and anim2
are two already set up QPropertyAnimation.

QSequentialAnimationGroup::QSequentialAnimationGroup | ( | QObject * | parent = 0 | ) |
Constructs a QSequentialAnimationGroup.
parent is passed to QObject's constructor.

QSequentialAnimationGroup::~QSequentialAnimationGroup | ( | ) |
Destroys the animation group.
It will also destroy all its animations.

QPauseAnimation * QSequentialAnimationGroup::addPause | ( | int | msecs | ) |
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.

QAbstractAnimation* QSequentialAnimationGroup::currentAnimation | ( | ) | const |
Referenced by QSequentialAnimationGroupPrivate::_q_uncontrolledAnimationFinished(), QSequentialAnimationGroupPrivate::activateCurrentAnimation(), QSequentialAnimationGroupPrivate::animationInsertedAt(), QSequentialAnimationGroupPrivate::animationRemoved(), insertPause(), and QSequentialAnimationGroupPrivate::setCurrentAnimation().
|
