注意
该类在 Qt4.6 引入
PySide.QtCore.QSequentialAnimationGroup class provides a sequential group of animations.
PySide.QtCore.QSequentialAnimationGroup 是 PySide.QtCore.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 PySide.QtCore.QAnimationGroup.addAnimation() or PySide.QtCore.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 PySide.QtCore.QSequentialAnimationGroup.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 PySide.QtCore.QSequentialAnimationGroup.addPause() or PySide.QtCore.QSequentialAnimationGroup.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 PySide.QtCore.QPropertyAnimation s.
| 参数： | parent – PySide.QtCore.QObject |
|---|
构造 PySide.QtCore.QSequentialAnimationGroup . parent 会被传递给 PySide.QtCore.QObject ‘s constructor.
| 参数： | msecs – PySide.QtCore.int |
|---|---|
| 返回类型： | PySide.QtCore.QPauseAnimation |
Adds a pause of msecs to this animation group. The pause is considered as a special type of animation, thus PySide.QtCore.QAnimationGroup.animationCount() will be increased by one.
| 返回类型： | PySide.QtCore.QAbstractAnimation |
|---|
Returns the animation in the current time.
| 参数： | current – PySide.QtCore.QAbstractAnimation |
|---|
| 参数： |
|
|---|---|
| 返回类型： |
Inserts a pause of msecs milliseconds at index in this animation group.
