Detailed Description¶
QGraphicsView
inherits the drag and drop functionality provided by QWidget . When it receives a drag and drop event, it translates it to a QGraphicsSceneDragDropEvent
.
QGraphicsSceneDragDropEvent
stores events of type GraphicsSceneDragEnter
, GraphicsSceneDragLeave
, GraphicsSceneDragMove
, or GraphicsSceneDrop
.
QGraphicsSceneDragDropEvent
contains the position of the mouse cursor in both item, scene, and screen coordinates; this can be retrieved with pos()
, scenePos()
, and screenPos()
.
The scene sends the event to the first QGraphicsItem
under the mouse cursor that accepts drops; a graphics item is set to accept drops with setAcceptDrops()
.
Constructs a new QGraphicsSceneDragDropEvent
of the specified type
. The type can be either GraphicsSceneDragEnter
, GraphicsSceneDragLeave
, GraphicsSceneDragMove
, or GraphicsSceneDrop
.
