Q_UNUSED(animation);
Q_ASSERT(animation == m_currentAnimation);
setUncontrolledAnimationFinishTime(m_currentAnimation, m_currentAnimation->currentTime());
int totalTime = currentTime();
if (m_direction == Forward) {
// set the current animation to be the next one
if (m_currentAnimation->nextSibling())

}示例2: rewindForwards
void QSequentialAnimationGroupJob::rewindForwards(const AnimationIndex &newAnimationIndex)
{
if (m_previousLoop > m_currentLoop) {
// we need to fast rewind to the beginning
for (QAbstractAnimationJob *anim = m_currentAnimation; anim; anim = anim->previousSibling()) {
RETURN_IF_DELETED(setCurrentAnimation(anim, true));
RETURN_IF_DELETED(anim->setCurrentTime(0));
}
// this will make sure the current animation is reset to the end
if (lastChild() && !lastChild()->previousSibling()) { //count == 1
// we need to force activation because setCurrentAnimation will have no effect
RETURN_IF_DELETED(activateCurrentAnimation());
} else {
RETURN_IF_DELETED(setCurrentAnimation(lastChild(), true));
}
}
// and now we need to fast rewind from the current position to
for (QAbstractAnimationJob *anim = m_currentAnimation; anim && anim != newAnimationIndex.animation; anim = anim->previousSibling()) {
RETURN_IF_DELETED(setCurrentAnimation(anim, true));
RETURN_IF_DELETED(anim->setCurrentTime(0));
}
