The QDragLeaveEvent class provides an event that is sent to a widget when a drag and drop action leaves it.
This event is always preceded by a QDragEnterEvent and a series of QDragMoveEvents. It is not sent if a QDropEvent is sent instead.
See also QDragEnterEvent, QDragMoveEvent, and QDropEvent.
Constructs a QDragLeaveEvent.
Warning: Do not create a QDragLeaveEvent yourself since these objects rely on Qt's internal state.
