The QSequentialAnimationGroup class provides a sequential group of animations. More...

Inherits QAnimationGroup.

Methods

• __init__ (self, QObject parent = None)
• QPauseAnimation addPause (self, int msecs)
• QAbstractAnimation currentAnimation (self)
• int duration (self)
• bool event (self, QEvent event)
• QPauseAnimation insertPause (self, int index, int msecs)
• updateCurrentTime (self, int)
• updateDirection (self, QAbstractAnimation.Direction direction)
• updateState (self, QAbstractAnimation.State newState, QAbstractAnimation.State oldState)

Qt Signals

• void currentAnimationChanged (QAbstractAnimation*)

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.

Method Documentation

QSequentialAnimationGroup.__init__ (self, QObject parent = None)

The parent argument, if not None, causes self to be owned by Qt instead of PyQt.

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

QPauseAnimation QSequentialAnimationGroup.addPause (self, 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().

QAbstractAnimation QSequentialAnimationGroup.currentAnimation (self)

int QSequentialAnimationGroup.duration (self)

Reimplemented from QAbstractAnimation.duration().

bool QSequentialAnimationGroup.event (self, QEvent event)

Reimplemented from QObject.event().

QPauseAnimation QSequentialAnimationGroup.insertPause (self, int index, int msecs)

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

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

QSequentialAnimationGroup.updateCurrentTime (self, int)

Reimplemented from QAbstractAnimation.updateCurrentTime().

QSequentialAnimationGroup.updateDirection (self, QAbstractAnimation.Direction direction)

Reimplemented from QAbstractAnimation.updateDirection().

QSequentialAnimationGroup.updateState (self, QAbstractAnimation.State newState, QAbstractAnimation.State oldState)

Reimplemented from QAbstractAnimation.updateState().

Qt Signal Documentation

void currentAnimationChanged (QAbstractAnimation*)

This is the default overload of this signal.

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

See also currentAnimation().
