.SH DESCRIPTION
The event sent to widgets when a drag-and-drop first drags onto it.
.PP
This event is always immediate followed by a QDragMoveEvent, thus you need only respond to one or the other event. Note that this class inherits most of its functionality from QDragMoveEvent, which in turn inherits most of its functionality from QDropEvent.
.PP
See also QDragLeaveEvent, QDragMoveEvent and QDropEvent.
