void advanceForwards(const AnimationIndex &newAnimationIndex)
This manages advancing the execution of a group running forwards (time has gone forward), which is the same behaviour for rewinding the execution of a group running backwards (time has gone backward).
void animationRemoved(int index, QAbstractAnimation *anim)
This method is called whenever an animation is removed from the group at index index.
#define QT_END_NAMESPACE
This macro expands to.
Definition: qglobal.h:90
The QSequentialAnimationGroup class provides a sequential group of animations.
#define QT_BEGIN_NAMESPACE
This macro expands to.
Definition: qglobal.h:89
void animationInsertedAt(int index)
This method is called whenever an animation is added to the group at index index. ...
The QAbstractAnimation class is the base of all animations.

void activateCurrentAnimation(bool intermediate=false)
void rewindForwards(const AnimationIndex &newAnimationIndex)
