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).
