Inherits QAnimationGroup.

### Methods

- __init__ (self, QObject parent = None)
- QPauseAnimation addPause (self, int)
- QAbstractAnimation currentAnimation (self)
- int duration (self)
- bool event (self, QEvent)
- QPauseAnimation insertPause (self, int, int)
- updateCurrentTime (self, int)
- updateDirection (self, QAbstractAnimation.Direction)
- updateState (self, QAbstractAnimation.State, QAbstractAnimation.State)

### Qt Signals

- void currentAnimationChanged (QAbstractAnimation *)

## 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.

## 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)

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)

Reimplemented from QObject.event().

### QPauseAnimation QSequentialAnimationGroup.insertPause (self, int, int)

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)

Reimplemented from QAbstractAnimation.updateDirection().

### QSequentialAnimationGroup.updateState (self, QAbstractAnimation.State, QAbstractAnimation.State)

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.
