QAnimationGroup::QAnimationGroup ( QObject * parent = 0 )

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

QAnimationGroup::~QAnimationGroup ()

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

void QAnimationGroup::addAnimation ( QAbstractAnimation * animation )

Adds animation to this group. This will call insertAnimation with index equals to animationCount().

Note: The group takes ownership of the animation.

See also removeAnimation().

QAbstractAnimation * QAnimationGroup::animationAt ( int index ) const

Returns a pointer to the animation at index in this group. This function is useful when you need access to a particular animation. index is between 0 and animationCount() - 1.

See also animationCount() and indexOfAnimation().

int QAnimationGroup::animationCount () const

Returns the number of animations managed by this group.

See also indexOfAnimation(), addAnimation(), and animationAt().

void QAnimationGroup::clear ()

Removes and deletes all animations in this animation group, and resets the current time to 0.

See also addAnimation() and removeAnimation().

bool QAnimationGroup::event ( QEvent * event ) [virtual protected]

Reimplemented from QObject::event().

int QAnimationGroup::indexOfAnimation ( QAbstractAnimation * animation ) const

Returns the index of animation. The returned index can be passed to the other functions that take an index as an argument.

See also insertAnimation(), animationAt(), and takeAnimation().

void QAnimationGroup::insertAnimation ( int index, QAbstractAnimation * animation )

Inserts animation into this animation group at index. If index is 0 the animation is inserted at the beginning. If index is animationCount(), the animation is inserted at the end.

Note: The group takes ownership of the animation.

See also takeAnimation(), addAnimation(), indexOfAnimation(), and removeAnimation().

void QAnimationGroup::removeAnimation ( QAbstractAnimation * animation )

Removes animation from this group. The ownership of animation is transferred to the caller.

See also takeAnimation(), insertAnimation(), and addAnimation().

QAbstractAnimation * QAnimationGroup::takeAnimation ( int index )

Returns the animation at index and removes it from the animation group.

Note: The ownership of the animation is transferred to the caller.
