示例1: setScrollOffset
void KItemListViewAnimation::setScrollOffset(qreal offset)
{
const qreal diff = m_scrollOffset - offset;
m_scrollOffset = offset;
// The change of the offset requires that the position of all
// animated QGraphicsWidgets get adjusted. An exception is made
// for the delete animation that should just fade away on the
// existing position.
for (int type = 0; type < AnimationTypeCount; ++type) {
if (type == DeleteAnimation) {
continue;
}
QHashIterator<QGraphicsWidget*, QPropertyAnimation*> it(m_animation[type]);
while (it.hasNext()) {
it.next();

QPropertyAnimation* propertyAnim = it.value();
QPointF currentPos = widget->pos();
if (m_scrollOrientation == Qt::Vertical) {
currentPos.ry() += diff;

if (type == MovingAnimation) {
// Stop the animation, calculate the moved start- and end-value
// and restart the animation for the remaining duration.
