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 () 或 insertPause () to add a pause to a sequential animation group.
QSequentialAnimationGroup *group = new QSequentialAnimationGroup; group->addAnimation(anim1); group->addAnimation(anim2); group->start();
在此范例中,
anim1
and
anim2
are two already set up

currentAnimation
:
QAbstractAnimation
*
注意: 此特性支持 QProperty 绑定。
This property holds the animation in the current time.
Constructs a QSequentialAnimationGroup. parent 会被传递给 QObject 的构造函数。

void
QSequentialAnimationGroup::
currentAnimationChanged
(
QAbstractAnimation

current
)
QSequentialAnimationGroup emits this signal when currentAnimation 已改变。 current is the current animation.
注意: 通知程序信号对于特性 currentAnimation .
另请参阅 currentAnimation ().
[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.
