Struct qt_gui::QNativeGestureEvent

#[repr(C)]
pub struct QNativeGestureEvent { /* fields omitted */ }

The QNativeGestureEvent class contains parameters that describe a gesture event.

C++ class: QNativeGestureEvent.

C++ documentation:

The QNativeGestureEvent class contains parameters that describe a gesture event.

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 equence
Qt::ZoomNativeGesture	Magnification delta in percent.	macOS: Two-finger pinch.
Qt::SmartZoomNativeGesture	Boolean magnification state.	macOS: Two-finger douple tap (trackpad) / One-finger douple tap (magic mouse).
Qt::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
