GestureRotate

open class GestureRotate : Gesture, GestureRotateProtocol

GtkGestureRotate is a GtkGesture implementation able to recognize 2-finger rotations, whenever the angle between both handled sequences changes, the GtkGestureRotate::angle-changed signal is emitted.

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

    Declaration

    Swift

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

    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 GestureRotate instance.

    Declaration

    Swift

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

    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 GestureRotate instance.

    Declaration

    Swift

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

    Parameters

    op

    gpointer to the underlying object
    Show on GitHub

  • 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 GestureRotate instance.

    Declaration

    Swift

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

    Parameters

    op

    pointer to the underlying object
