class GestureSwipe(**properties: Any)
Superclasses: GestureSingle, Gesture, EventController, Object
GtkGestureSwipe is a GtkGesture for swipe gestures.
After a press/move/…/move/release sequence happens, the
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,
get_velocity can be called in a
update handler.
All velocities are reported in pixels/sec units.
Constructors
-
class GestureSwipe

in velocity_x and velocity_y with the recorded velocity, as per the
last events processed.
Signals
-
class GestureSwipe.signals
-
swipe(velocity_x: float, velocity_y: float) → None
The type of the None singleton.

velocity_y – velocity in the Y axis, in pixels/sec
