QParallelAnimationGroup--a container for animations --starts all its animations when it is started itself, i.e., runs all animations in parallel. The animation group finishes when the longest lasting animation has finished.
You can treat QParallelAnimationGroup as any other QAbstractAnimation , e.g., pause, resume, or add it to other animation groups.
QParallelAnimationGroup *group = new QParallelAnimationGroup; group->addAnimation(anim1); group->addAnimation(anim2); group->start();
在此范例中,
anim1
and
anim2
are two
QPropertyAnimation
s that have already been set up.

构造 QParallelAnimationGroup。 parent 会被传递给 QObject 的构造函数。
