Detailed Description¶
QGraphicsView
inherits the drag and drop functionality provided byQWidget
. When it receives a drag and drop event, it translates it to aQGraphicsSceneDragDropEvent
.
QGraphicsSceneDragDropEvent
stores events of typeGraphicsSceneDragEnter
,GraphicsSceneDragLeave
,GraphicsSceneDragMove
, orGraphicsSceneDrop
.
QGraphicsSceneDragDropEvent
contains the position of the mouse cursor in both item, scene, and screen coordinates; this can be retrieved withpos()
,scenePos()
, andscreenPos()
.The scene sends the event to the first
QGraphicsItem
under the mouse cursor that accepts drops; a graphics item is set to accept drops withsetAcceptDrops()
.
