我在QListView上使用QScroller.

Answer 1

你必须设置的超调政策QScrollerProperties.这是垂直滚动的示例:

QScrollerProperties properties = QScroller::scroller(scrollWidget)->scrollerProperties();

QVariant overshootPolicy = QVariant::fromValue<QScrollerProperties::OvershootPolicy>(QScrollerProperties::OvershootAlwaysOff);
properties.setScrollMetric(QScrollerProperties::VerticalOvershootPolicy, overshootPolicy);

QScroller::scroller(scrollWidget)->setScrollerProperties(properties);
