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() ).

class PySide2.QtWidgets.QGraphicsSceneWheelEvent([type=None])
param type

Type

Constructs a QGraphicsSceneWheelEvent of type type , which is always GraphicsSceneWheel .

PySide2.QtWidgets.QGraphicsSceneWheelEvent.buttons()
Return type

MouseButtons

Returns the mouse buttons that were pressed when the wheel event occurred.

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).

PySide2.QtWidgets.QGraphicsSceneWheelEvent.modifiers()
Return type

KeyboardModifiers

Returns the keyboard modifiers that were active when the wheel event occurred.

PySide2.QtWidgets.QGraphicsSceneWheelEvent.pos()
Return type

PySide2.QtCore.QPointF

Returns the position of the cursor in item coordinates when the wheel event occurred.

PySide2.QtWidgets.QGraphicsSceneWheelEvent.scenePos()
Return type

PySide2.QtCore.QPointF

Returns the position of the cursor in scene coordinates when the wheel event occurred.
