TouchpadEventProtocol

public protocol TouchpadEventProtocol : EventProtocol

The TouchpadEventProtocol protocol exposes the methods and properties of an underlying GdkTouchpadEvent instance. The default implementation of these can be found in the protocol extension below. For a concrete class that implements these methods and properties, see TouchpadEvent. Alternatively, use TouchpadEventRef as a lighweight, unowned reference if you already have an instance you just want to use.

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.
