public sealed class GestureSwipe : GestureSingle

GestureSwipe is a Gesture implementation able to recognize swipes, 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 on eg. a update handler.

All velocities are reported in pixels/sec units.

Namespace: Gtk

Package: gtk+-3.0

Creation methods:

public GestureSwipe (Widget widget)
Returns a newly created Gesture that recognizes swipes.

Methods:

public bool get_velocity (out double velocity_x, out double velocity_y)
If the gesture is recognized, this function returns true and fill in velocity_x and velocity_y with the recorded velocity, as per the last event(s) processed.

Signals:

public signal void swipe (double velocity_x, double velocity_y)
This signal is emitted when the recognized gesture is finished, velocity and direction are a product of previously recorded events.
