GestureRotateRef

public struct GestureRotateRef : GestureRotateProtocol, GWeakCapturing

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 GestureRotateRef type acts as a lightweight Swift reference to an underlying GtkGestureRotate instance. It exposes methods that can operate on this data type through GestureRotateProtocol conformance. Use GestureRotateRef only as an unowned reference to an existing GtkGestureRotate instance.

  • ptr
    Untyped pointer to the underlying `GtkGestureRotate` instance.
    

    For type-safe access, use the generated, typed pointer gesture_rotate_ptr property instead.

    Declaration

    Swift

    public let ptr: UnsafeMutableRawPointer!

GestureRotate Class

    Declaration

    Swift

    Declaration

    Swift

    @inlinable
    static func unowned<T>(_ other: T) -> GestureRotateRef where T : GestureRotateProtocol
  • Unsafe typed initialiser. Do not use unless you know the underlying data type the pointer points to conforms to GestureRotateProtocol.

    Declaration

    Swift
