Detailed Description¶

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

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

__init__([type=QEvent.Type.None])¶

Parameters:: type – Type

buttons()¶

Return type:: Combination of MouseButton

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

See also

modifiers()

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).

isInverted()¶

Return type:: bool

Returns whether the delta values delivered with the event are inverted.

modifiers()¶

Return type:: Combination of KeyboardModifier

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

buttons()

orientation()¶

Return type:: Orientation

Returns the wheel orientation.

phase()¶

Return type:: ScrollPhase

Returns the scrolling phase of this wheel event.

phase

pixelDelta()¶

Return type:: QPoint

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.

pixelDelta

pos()¶

Return type:: QPointF

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

scenePos() screenPos()

scenePos()¶

Return type:: QPointF

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

See also

pos() screenPos()

screenPos()¶

Return type:: QPoint

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