Detailed Description¶

The QGraphicsSceneWheelEvent class provides wheel events in the graphics view framework.

QWheelEvent s received by a QGraphicsView are translated into QGraphicsSceneWheelEvents; it translates the globalPos() into item, scene, and screen coordinates ( pos() , scenePos() , and screenPos() ).

modifiers()

PySide2.QtWidgets.QGraphicsSceneWheelEvent.delta()¶

Return type: int

Returns the distance that the wheel is rotated, in eighths (1/8s) of a degree. A positive value indicates that the wheel was rotated forwards away from the user; a negative value indicates that the wheel was rotated backwards toward the user.

Most mouse types work in steps of 15 degrees, in which case the delta value is a multiple of 120 (== 15 * 8).
