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, i.e., 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.

 QSequentialAnimationGroup *group = new QSequentialAnimationGroup;

 group->addAnimation(anim1);
 group->addAnimation(anim2);

 group->start();

In this example, anim1 and anim2 are two already set up QPropertyAnimations.

Property Documentation

currentAnimation : QAbstractAnimation * const

Returns the animation in the current time.

Access functions:

QAbstractAnimation * currentAnimation () const

Notifier signal:

void	currentAnimationChanged ( QAbstractAnimation * current )

See also currentAnimationChanged().

Member Function Documentation

QSequentialAnimationGroup::QSequentialAnimationGroup ( QObject * parent = 0 )

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

QSequentialAnimationGroup::~QSequentialAnimationGroup ()

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

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() and QAnimationGroup::addAnimation().

void QSequentialAnimationGroup::currentAnimationChanged ( QAbstractAnimation * current ) `[signal]`

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

See also currentAnimation().

int QSequentialAnimationGroup::duration () const `[virtual]`

Reimplemented from QAbstractAnimation::duration().

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

Reimplemented from QObject::event().

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

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

See also addPause() and QAnimationGroup::insertAnimation().

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

Reimplemented from QAbstractAnimation::updateCurrentTime().

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

Reimplemented from QAbstractAnimation::updateDirection().

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

Reimplemented from QAbstractAnimation::updateState().
