The scroll event is sent to indicate that the receiver should be scrolled. Usually the receiver should be something visual like QWidget or QGraphicsObject.

Some care should be taken that no conflicting QScrollEvents are sent from two sources. Using QScroller::scrollTo is save however.

Return type:: ScrollState

Returns the current scroll state as a combination of ScrollStateFlag values. ScrollStarted (or ScrollFinished ) will be set, if this scroll event is the first (or last) event in a scrolling activity.

A widget could for example revert selections when scrolling is started and stopped.
