## Detailed Description

The QParallelAnimationGroup class provides a parallel group of animations.

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.

## Member Function Documentation

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

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

### QParallelAnimationGroup::~QParallelAnimationGroup()

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

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

Reimplemented from QAbstractAnimation::duration().

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

Reimplemented from QObject::event().

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

Reimplemented from QAbstractAnimation::updateCurrentTime().

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

Reimplemented from QAbstractAnimation::updateDirection().

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

Reimplemented from QAbstractAnimation::updateState().
