VolumeButtonRef

public struct VolumeButtonRef : VolumeButtonProtocol, GWeakCapturing

GtkVolumeButton is a subclass of GtkScaleButton that has been tailored for use as a volume control widget with suitable icons, tooltips and accessible labels.

The VolumeButtonRef type acts as a lightweight Swift reference to an underlying GtkVolumeButton instance. It exposes methods that can operate on this data type through VolumeButtonProtocol conformance. Use VolumeButtonRef only as an unowned reference to an existing GtkVolumeButton instance.

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

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

    Declaration

    Swift

    public let ptr: UnsafeMutableRawPointer!

VolumeButton Class

  • Designated initialiser from the underlying C data type

    Declaration

    Swift

    @inlinable
    init(_ p: UnsafeMutablePointer<GtkVolumeButton>)
  • Designated initialiser from a constant pointer to the underlying C data type

    Declaration

    Swift

    @inlinable
    init(_ p: UnsafePointer<GtkVolumeButton>)
  • Conditional initialiser from an optional pointer to the underlying C data type

    Declaration

    Swift

    @inlinable
    init!(_ maybePointer: UnsafeMutablePointer<GtkVolumeButton>?)
  • Conditional initialiser from an optional, non-mutable pointer to the underlying C data type

    Declaration

    Swift

    @inlinable
    init!(_ maybePointer: UnsafePointer<GtkVolumeButton>?)
  • Conditional initialiser from an optional gpointer

    Declaration

    Swift

    @inlinable
    init!(gpointer g: gpointer?)
  • Conditional initialiser from an optional, non-mutable gconstpointer

    Declaration

    Swift

    @inlinable
    init!(gconstpointer g: gconstpointer?)
  • Reference intialiser for a related type that implements VolumeButtonProtocol

    Declaration

    Swift

    @inlinable
    init<T>(_ other: T) where T : VolumeButtonProtocol
  • This factory is syntactic sugar for setting weak pointers wrapped in GWeak<T>

    Declaration

    Swift

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

    Declaration

    Swift

    @inlinable
    init<T>(cPointer: UnsafeMutablePointer<T>)
  • Unsafe typed initialiser. Do not use unless you know the underlying data type the pointer points to conforms to VolumeButtonProtocol.

    Declaration

    Swift

    @inlinable
    init<T>(constPointer: UnsafePointer<T>)
  • Unsafe untyped initialiser. Do not use unless you know the underlying data type the pointer points to conforms to VolumeButtonProtocol.

    Declaration

    Swift

    @inlinable
    init(mutating raw: UnsafeRawPointer)
  • Unsafe untyped initialiser. Do not use unless you know the underlying data type the pointer points to conforms to VolumeButtonProtocol.

    Declaration

    Swift

    @inlinable
    init(raw: UnsafeMutableRawPointer)
  • Unsafe untyped initialiser. Do not use unless you know the underlying data type the pointer points to conforms to VolumeButtonProtocol.

    Declaration

    Swift

    @inlinable
    init(opaquePointer: OpaquePointer)
  • Creates a `GtkVolumeButton`, with a range between 0.0 and 1.0, with
    

    a stepping of 0.02. Volume values can be obtained and modified using the functions from GtkScaleButton.

    Declaration

    Swift

    @inlinable
    init()
