public class GestureSwipe
extends GestureSingle

`GtkGestureSwipe` is a `GtkGesture` for swipe gestures.

After a press/move/.../move/release sequence happens, the
[signal@Gtk.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,
[method@Gtk.GestureSwipe.get_velocity] can be called in a
[signal@Gtk.Gesture::update] handler.

All velocities are reported in pixels/sec units.
