Detailed Description

Native gesture events are generated by the operating system, typically by interpreting touch events. Gesture events are high-level events such as zoom or rotate.

Event Type	Description	Touch sequence
ZoomNativeGesture	Magnification delta in percent.	macOS : Two-finger pinch.
SmartZoomNativeGesture	Boolean magnification state.	macOS : Two-finger douple tap (trackpad) / One-finger douple tap (magic mouse).
RotateNativeGesture	Rotation delta in degrees.	macOS : Two-finger rotate.

In addition, BeginNativeGesture and EndNativeGesture are sent before and after gesture event streams:

BeginNativeGesture ZoomNativeGesture ZoomNativeGesture ZoomNativeGesture EndNativeGesture

Constructs a native gesture event of type type originating from device .

The points localPos , windowPos and screenPos specify the gesture position relative to the receiving widget or item, window, and screen, respectively.

realValue is the macOS event parameter, sequenceId and intValue are the Windows event parameters.

PySide2.QtGui.QNativeGestureEvent.device()

Return type

QTouchDevice

Returns the device.

PySide2.QtGui.QNativeGestureEvent.gestureType()

Return type

NativeGestureType

Returns the gesture type.

PySide2.QtGui.QNativeGestureEvent.globalPos()

Return type

QPoint

Returns the position of the gesture as a QPointF in screen coordinates

PySide2.QtGui.QNativeGestureEvent.localPos()

Return type

QPointF

Returns the position of the gesture as a QPointF , relative to the widget or item that received the event.

PySide2.QtGui.QNativeGestureEvent.pos()

Return type

QPoint

Returns the position of the mouse cursor, relative to the widget or item that received the event.

PySide2.QtGui.QNativeGestureEvent.screenPos()

Return type

QPointF

Returns the position of the gesture as a QPointF in screen coordinates.

PySide2.QtGui.QNativeGestureEvent.value()

Return type

qreal

Returns the gesture value. The value should be interpreted based on the gesture type. For example, a Zoom gesture provides a scale factor while a Rotate gesture provides a rotation delta.
