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() .

__init__([type=QEvent.Type.None])#

Parameters:: type – Type

acceptProposedAction()#

Warning

This section contains snippets that were automatically translated from C++ to Python and may contain errors.

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().

buttons()#

Return type:: Combination of MouseButton

Returns a Qt::MouseButtons value indicating which buttons were pressed on the mouse when this mouse event was generated.

MouseButtons

dropAction()#

Return type:: DropAction

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().

mimeData()#

Return type:: QMimeData

This function returns the MIME data of the event.

modifiers()#

Return type:: Combination of KeyboardModifier

Returns the keyboard modifiers that were pressed when the drag and drop event was created.

possibleActions()#

Return type:: Combination of DropAction

Returns the possible drop actions that the drag and drop can result in.

proposedAction()#

Return type:: DropAction

Returns the drop action that is proposed, i.e., preferred. The action must be one of the possible actions as defined by possibleActions().

Parameters:: action – DropAction

setScenePos(pos)#

Parameters:: pos – QPointF

setScreenPos(pos)#

Parameters:: pos – QPoint

source()#

Return type:: QWidget

This function returns the QGraphicsView that created the QGraphicsSceneDragDropEvent .
