Detailed Description

The scroll prepare event is sent before scrolling (usually by QScroller ) is started. The object receiving this event should set viewportSize , maxContentPos and contentPos . It also should accept this event to indicate that scrolling should be started.

It is not guaranteed that a QScrollEvent will be sent after an accepted QScrollPrepareEvent , e.g. in a case where the maximum content position is (0, 0).
