重实现保护函数

详细描述

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.

成员函数文档编制

QParallelAnimationGroup:: QParallelAnimationGroup ( QObject * parent = nullptr)

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

[virtual] QParallelAnimationGroup:: ~QParallelAnimationGroup ()

Destroys the animation group. It will also destroy all its animations.

[override virtual] int QParallelAnimationGroup:: duration () const

重实现： QAbstractAnimation::duration () const.

[override virtual protected] bool QParallelAnimationGroup:: event ( QEvent * event )

重实现： QAnimationGroup::event (QEvent *event).

[override virtual protected] void QParallelAnimationGroup:: updateCurrentTime ( int currentTime )

重实现： QAbstractAnimation::updateCurrentTime (int currentTime).

[override virtual protected] void QParallelAnimationGroup:: updateDirection ( QAbstractAnimation::Direction direction )

重实现： QAbstractAnimation::updateDirection (QAbstractAnimation::Direction direction).

[override virtual protected] void QParallelAnimationGroup:: updateState ( QAbstractAnimation::State newState , QAbstractAnimation::State oldState )

重实现： QAbstractAnimation::updateState (QAbstractAnimation::State newState, QAbstractAnimation::State oldState).
