Detailed Description

\inmodule QtCore

The QParallelAnimationGroup class provides a parallel group of animations.

Since: 4.6

QParallelAnimationGroup–a \l{QAnimationGroup}{container for animations}–starts all its animations when it is \l{QAbstractAnimation::start()}{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();
