QSequentialAnimationGroup ¶

概要 ¶

详细描述 ¶

QSequentialAnimationGroup 是 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();
											

在此范例中， anim1 and anim2 are two already set up QPropertyAnimation s.

class QSequentialAnimationGroup ( [ parent=None ] ) ¶

param parent

QObject

构造 QSequentialAnimationGroup . parent 会被传递给 QObject ‘s constructor.

PySide2.QtCore.QSequentialAnimationGroup. addPause ( msecs ) ¶

参数

msecs – int

返回类型

QPauseAnimation

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.

返回类型

QAbstractAnimation

PySide2.QtCore.QSequentialAnimationGroup. currentAnimationChanged ( current ) ¶

参数

current – QAbstractAnimation

PySide2.QtCore.QSequentialAnimationGroup. insertPause ( index , msecs ) ¶

参数

• index – int
