GestureSwipe

open class GestureSwipe : GestureSingle, GestureSwipeProtocol

GtkGestureSwipe is a GtkGesture implementation able to recognize swipes, after a press/move/…/move/release sequence happens, the GtkGestureSwipe::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, gtk_gesture_swipe_get_velocity() can be called on eg. a GtkGesture::update handler.

All velocities are reported in pixels/sec units.

The GestureSwipe type acts as a reference-counted owner of an underlying GtkGestureSwipe instance. It provides the methods that can operate on this data type through GestureSwipeProtocol conformance. Use GestureSwipe as a strong reference or owner of a GtkGestureSwipe instance.

  • Designated initialiser from the underlying `C` data type.

    This creates an instance without performing an unbalanced retain i.e., ownership is transferred to the GestureSwipe instance.

    Declaration

    Swift

    @inlinable
public init(_ op: UnsafeMutablePointer<GtkGestureSwipe>)

    Parameters

    op

    pointer to the underlying object
    Show on GitHub

  • Designated initialiser from a constant pointer to the underlying C data type. This creates an instance without performing an unbalanced retain i.e., ownership is transferred to the GestureSwipe instance.

    Declaration

    Swift

    @inlinable
public init(_ op: UnsafePointer<GtkGestureSwipe>)

    Parameters

    op

    pointer to the underlying object

  • Optional initialiser from a non-mutating gpointer to the underlying C data type. This creates an instance without performing an unbalanced retain i.e., ownership is transferred to the GestureSwipe instance.

    Declaration

    Swift

    @inlinable
override public init!(gpointer op: gpointer?)

    Parameters

    op

    gpointer to the underlying object

  • Optional initialiser from a non-mutating gconstpointer to the underlying C data type. This creates an instance without performing an unbalanced retain i.e., ownership is transferred to the GestureSwipe instance.

    Declaration

    Swift

override public init!(gconstpointer op: gconstpointer?)

    Parameters

    op
