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().
Member Function Documentation▲
[virtual] QGraphicsSceneDragDropEvent::~QGraphicsSceneDragDropEvent()▲
Destroys the object.
void QGraphicsSceneDragDropEvent::acceptProposedAction()▲
Sets the proposed action as accepted, i.e, the drop action is set to the proposed action. This is equal to:
setDropAction(proposedAction());When using this function, one should not call accept().

Qt::DropAction QGraphicsSceneDragDropEvent::dropAction() const▲
Returns the action that was performed in this drag and drop. This should be set by the receiver of the drop and is returned by QDrag::exec().

const QMimeData *QGraphicsSceneDragDropEvent::mimeData() const▲
This function returns the MIME data of the event.
Qt::KeyboardModifiers QGraphicsSceneDragDropEvent::modifiers() const▲
Returns the keyboard modifiers that were pressed when the drag and drop event was created.

QPointF QGraphicsSceneDragDropEvent::pos() const▲
Returns the mouse position of the event relative to the view that sent the event.

Qt::DropActions QGraphicsSceneDragDropEvent::possibleActions() const▲
Returns the possible drop actions that the drag and drop can result in.

See also Qt::DropActions
Qt::DropAction QGraphicsSceneDragDropEvent::proposedAction() const▲
Returns the drop action that is proposed, i.e., preferred. The action must be one of the possible actions as defined by possibleActions().

QPointF QGraphicsSceneDragDropEvent::scenePos() const▲
QPoint QGraphicsSceneDragDropEvent::screenPos() const▲
void QGraphicsSceneDragDropEvent::setDropAction(Qt::DropAction action)▲
This function lets the receiver of the drop set the drop action that was performed to action, which should be one of the possible actions. Call accept() in stead of acceptProposedAction() if you use this function.

QWidget *QGraphicsSceneDragDropEvent::source() const▲
This function returns the QGraphicsView that created the QGraphicsSceneDragDropEvent.
