Detailed Description#

When a QGraphicsView receives a QMouseEvent, it translates it to a QGraphicsSceneMouseEvent . The event is then forwarded to the QGraphicsScene associated with the view. If the event is not handled by the scene, the view may use it, e.g., for the DragMode .

In addition to containing the item, scene, and screen coordinates of the event (as pos() , scenePos() , and screenPos() ), mouse events also contain the coordinates of the previous mouse event received by the view. These can be retrieved with lastPos() , lastScreenPos() , and lastScenePos() .

button() modifiers()

PySide6.QtWidgets.QGraphicsSceneMouseEvent.flags()#

Return type:: Combination of Qt.MouseEventFlag

Returns the mouse event flags.

The mouse event flags provide additional information about a mouse event.

flags()

PySide6.QtWidgets.QGraphicsSceneMouseEvent.lastPos()#

Return type:: PySide6.QtCore.QPointF

Returns the last recorded mouse cursor position in item coordinates.

See also

lastScenePos() lastScreenPos() pos()

PySide6.QtWidgets.QGraphicsSceneMouseEvent.lastScenePos()#

Return type:: PySide6.QtCore.QPointF

Returns the last recorded mouse cursor position in scene coordinates. The last recorded position is the position of the previous mouse event received by the view that created the event.

PySide6.QtWidgets.QGraphicsSceneMouseEvent.lastScreenPos()#

Return type:: PySide6.QtCore.QPoint

Returns the last recorded mouse cursor position in screen coordinates. The last recorded position is the position of the previous mouse event received by the view that created the event.

Parameters:: buttons – Combination of Qt.MouseButton

PySide6.QtWidgets.QGraphicsSceneMouseEvent.setFlags(arg__1)#

Parameters:: arg__1 – Combination of Qt.MouseEventFlag

PySide6.QtWidgets.QGraphicsSceneMouseEvent.setLastPos(pos)#

Parameters:: pos – PySide6.QtCore.QPointF

PySide6.QtWidgets.QGraphicsSceneMouseEvent.setSource(source)#

Parameters:: source – MouseEventSource

PySide6.QtWidgets.QGraphicsSceneMouseEvent.source()#

Return type:: MouseEventSource

Returns information about the mouse event source.

The mouse event source can be used to distinguish between genuine and artificial mouse events. The latter are events that are synthesized from touch events by the operating system or Qt itself.
