GestureSwipeRef

public struct GestureSwipeRef : GestureSwipeProtocol, GWeakCapturing

GtkGestureSwipe is a GtkGesture for swipe gestures.

After a press/move/…/move/release sequence happens, the [signalGtk.GestureSwipe::swipe] signal will be emitted, providing the velocity and directionality of the sequence at the time it was lifted.

If the velocity is desired in intermediate points, [methodGtk.GestureSwipe.get_velocity] can be called in a [signalGtk.Gesture::update] handler.

All velocities are reported in pixels/sec units.

The GestureSwipeRef type acts as a lightweight Swift reference to an underlying GtkGestureSwipe instance. It exposes methods that can operate on this data type through GestureSwipeProtocol conformance. Use GestureSwipeRef only as an unowned reference to an existing GtkGestureSwipe instance.

  • ptr 
    Untyped pointer to the underlying `GtkGestureSwipe` instance.

    For type-safe access, use the generated, typed pointer gesture_swipe_ptr property instead.
