GestureStylusProtocol

public protocol GestureStylusProtocol : GestureSingleProtocol

GtkGestureStylus is a GtkGesture implementation specific to stylus input. The provided signals just provide the basic information

The GestureStylusProtocol protocol exposes the methods and properties of an underlying GtkGestureStylus 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 GestureStylus. Alternatively, use GestureStylusRef as a lighweight, unowned reference if you already have an instance you just want to use.
