Synopsis

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() .

PySide6.QtWidgets.QGraphicsSceneMouseEvent.setSource(source)
Parameters

sourceMouseEventSource

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.
