Detailed Description

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().

Constructor & Destructor Documentation

QtGui.QGraphicsSceneDragDropEvent.QGraphicsSceneDragDropEvent ( System.Type  dummy)
protected
QtGui.QGraphicsSceneDragDropEvent.QGraphicsSceneDragDropEvent ( QEvent.Type  type = QEvent.Type.None)

Here is the call graph for this function:

Member Function Documentation

new void QtGui.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().

See also dropAction(), setDropAction(), and proposedAction().

override void QtGui.QGraphicsSceneDragDropEvent.CreateProxy ( )
virtual

Reimplemented from QtCore.QEvent.

Here is the caller graph for this function:

new void QtGui.QGraphicsSceneDragDropEvent.Dispose ( )

Property Documentation

Qt.MouseButton QtGui.QGraphicsSceneDragDropEvent.Buttons
getset

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

Qt.DropAction QtGui.QGraphicsSceneDragDropEvent.DropAction
getset

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().

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.

QMimeData QtGui.QGraphicsSceneDragDropEvent.MimeData
getset

This function returns the MIME data of the event.

Qt.KeyboardModifier QtGui.QGraphicsSceneDragDropEvent.Modifiers
getset

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

QPointF QtGui.QGraphicsSceneDragDropEvent.Pos
getset

Returns the mouse position of the event relative to the view that sent the event.

Qt.DropAction QtGui.QGraphicsSceneDragDropEvent.PossibleActions
getset

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

Qt.DropAction QtGui.QGraphicsSceneDragDropEvent.ProposedAction
getset

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

QPointF QtGui.QGraphicsSceneDragDropEvent.ScenePos
getset

Returns the position of the mouse in scene coordinates.

QPoint QtGui.QGraphicsSceneDragDropEvent.ScreenPos
getset

Returns the position of the mouse relative to the screen.

QWidget QtGui.QGraphicsSceneDragDropEvent.Source
getset

This function returns the QGraphicsView that created the QGraphicsSceneDragDropEvent.
