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.

  • ptr

    Untyped pointer to the underlying GtkGestureStylus instance.

    Declaration

    Swift

    var ptr: UnsafeMutableRawPointer! { get }
  • gesture_stylus_ptr Default implementation

    Typed pointer to the underlying GtkGestureStylus instance.

    Default Implementation

    Return the stored, untyped pointer as a typed pointer to the GtkGestureStylus instance.

    Declaration

    Swift

    var gesture_stylus_ptr: UnsafeMutablePointer<GtkGestureStylus>! { get }
  • Required Initialiser for types conforming to GestureStylusProtocol

    Declaration
