[ CCode ( type_id = "gdk_touchpad_event_get_type ()" ) ]
public sealed class TouchpadEvent : Event

An event related to a gesture on a touchpad device.

Unlike touchscreens, where the windowing system sends basic sequences of begin, update, end events, and leaves gesture recognition to the clients, touchpad gestures are typically processed by the system, resulting in these events.
