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 QWheelEvent::globalPos() into item, scene, and screen coordinates ( pos() , scenePos() , and screenPos() ).

- PySide6.QtWidgets.QGraphicsSceneWheelEvent.buttons()#
- Return type
MouseButtons
Returns the mouse buttons that were pressed when the wheel event occurred.
See also
- PySide6.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).
- PySide6.QtWidgets.QGraphicsSceneWheelEvent.isInverted()#
- Return type
bool
Returns whether the delta values delivered with the event are inverted.
- PySide6.QtWidgets.QGraphicsSceneWheelEvent.modifiers()#
- Return type
KeyboardModifiers
Returns the keyboard modifiers that were active when the wheel event occurred.
See also
- PySide6.QtWidgets.QGraphicsSceneWheelEvent.orientation()#
- Return type
Returns the wheel orientation.
- PySide6.QtWidgets.QGraphicsSceneWheelEvent.phase()#
- Return type
Returns the scrolling phase of this wheel event.

phase
- PySide6.QtWidgets.QGraphicsSceneWheelEvent.pixelDelta()#
- Return type
Returns the scrolling distance in pixels on screen. This value is provided on platforms that support high-resolution pixel-based delta values, such as macOS. The value should be used directly to scroll content on screen.

- PySide6.QtWidgets.QGraphicsSceneWheelEvent.pos()#
- Return type
Returns the position of the cursor in item coordinates when the wheel event occurred.

- PySide6.QtWidgets.QGraphicsSceneWheelEvent.scenePos()#
- Return type
Returns the position of the cursor in scene coordinates when the wheel event occurred.
See also
- PySide6.QtWidgets.QGraphicsSceneWheelEvent.screenPos()#
- Return type
Returns the position of the cursor in screen coordinates when the wheel event occurred.
