Struct QGraphicsSceneDragDropEvent

#[repr(C)]
pub struct QGraphicsSceneDragDropEvent { /* private fields */ }

The QGraphicsSceneDragDropEvent class provides events for drag and drop in the graphics view framework.

C++ class: QGraphicsSceneDragDropEvent.

C++ documentation:

The QGraphicsSceneDragDropEvent class provides events for drag and drop in the graphics view framework.

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().

Implementations

impl QGraphicsSceneDragDropEvent

pub unsafe fn accept_proposed_action(&self)

Sets the proposed action as accepted, i.e, the drop action is set to the proposed action. This is equal to:

Calls C++ function: void QGraphicsSceneDragDropEvent::acceptProposedAction().

C++ documentation:

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().
