Detailed Description

The QSequentialAnimationGroup class provides a sequential group of animations.

QSequentialAnimationGroup is a QAnimationGroup that runs its animations in sequence, i.e., it starts one animation after another has finished playing. The animations are played in the order they are added to the group (using addAnimation() or insertAnimation()). The animation group finishes when its last animation has finished.

At each moment there is at most one animation that is active in the group, it is returned by currentAnimation(). An empty group has no current animation. A sequential animation group can be treated as any other animation, for example it can be started, stopped, and added to other groups. You can also call addPause() or insertPause() to add a pause to a sequential animation group.

In this example anim1 and anim2 are existing QPropertyAnimations.

QSequentialAnimationGroup *group = new QSequentialAnimationGroup;
 
group->addAnimation(anim1);
group->addAnimation(anim2);
 
group->start();

Constructor & Destructor Documentation

QSequentialAnimationGroup::QSequentialAnimationGroup ( QObject * parent = nullptr )

Constructs a QSequentialAnimationGroup. The parent is passed to the QObject constructor.

QSequentialAnimationGroup::~QSequentialAnimationGroup ( )

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

Method Documentation

QPauseAnimation * QSequentialAnimationGroup::addPause ( int msecs )

Adds a pause of msecs to this animation group. The pause is considered as a special type of animation, thus animationCount will be increased by one.

See also: insertPause(), QAnimationGroup::addAnimation()

QAbstractAnimation * QSequentialAnimationGroup::currentAnimation ( ) const

Returns the value of the property currentAnimation which contains the animation in the current time.

void QSequentialAnimationGroup::currentAnimationChanged ( QAbstractAnimation * current )

signal

QSequentialAnimationGroup emits this signal when currentAnimation has been changed. The parameter current is the current animation.

See also: currentAnimation()

int QSequentialAnimationGroup::duration ( ) const

overridevirtual

Implements QAbstractAnimation::duration()

bool QSequentialAnimationGroup::event ( QEvent * event )

overrideprotectedvirtual

Reimplemented from QAnimationGroup::event()

QPauseAnimation * QSequentialAnimationGroup::insertPause	(	int	index,
		int	msecs
	)

Inserts a pause of msecs milliseconds at index in this animation group.

See also: addPause(), QAnimationGroup::insertAnimation()

void QSequentialAnimationGroup::updateCurrentTime ( int currentTime )

overrideprotectedvirtual

Implements QAbstractAnimation::updateCurrentTime()

void QSequentialAnimationGroup::updateDirection ( QAbstractAnimation::Direction direction )

overrideprotectedvirtual

Reimplemented from QAbstractAnimation::updateDirection()

void QSequentialAnimationGroup::updateState	(	QAbstractAnimation::State	newState,
		QAbstractAnimation::State	oldState
	)

overrideprotectedvirtual

Reimplemented from QAbstractAnimation::updateState()

Property Documentation

QSequentialAnimationGroup::currentAnimation

Returns the animation in the current time.
