Synopsis

Functions

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() .

class PySide2.QtWidgets.QGraphicsSceneDragDropEvent([type=None])
param type

Type

Constructs a new QGraphicsSceneDragDropEvent of the specified type . The type can be either GraphicsSceneDragEnter , GraphicsSceneDragLeave , GraphicsSceneDragMove , or GraphicsSceneDrop .

PySide2.QtWidgets.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() .
