## Detailed Description

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();

In this example, `anim1` and `anim2` are two QPropertyAnimations that have already been set up.

### QParallelAnimationGroup::QParallelAnimationGroup(QObject *parent = nullptr)

Constructs a QParallelAnimationGroup. parent is passed to QObject's constructor.

### `[virtual]` QParallelAnimationGroup::~QParallelAnimationGroup()

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

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

Reimplements: QAbstractAnimation::duration() const.

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

Reimplements: QAnimationGroup::event(QEvent *event).

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

Reimplements: QAbstractAnimation::updateCurrentTime(int currentTime).

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

Reimplements: QAbstractAnimation::updateDirection(QAbstractAnimation::Direction direction).

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

Reimplements: QAbstractAnimation::updateState(QAbstractAnimation::State newState, QAbstractAnimation::State oldState).
