Class
GtkGestureSwipe
Description [src]
final class Gtk.GestureSwipe : Gtk.GestureSingle
{
/* No available fields */
}GtkGestureSwipe is a GtkGesture for swipe gestures.
After a press/move/…/move/release sequence happens, the
GtkGestureSwipe::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,
gtk_gesture_swipe_get_velocity() can be called in a
GtkGesture::update handler.
All velocities are reported in pixels/sec units.

Signals
Signals inherited from GtkGesture (5)
GtkGesture::begin
Emitted when the gesture is recognized.

GtkGesture::update
Emitted whenever an event is handled while the gesture is recognized.
Signals inherited from GObject (1)
