VolumeButton

open class VolumeButton : ScaleButton, VolumeButtonProtocol

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

    Declaration

    Swift

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

    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 VolumeButton instance.

    Declaration

    Swift

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

    Parameters

    op

    pointer to the underlying object
    Show on GitHub

  • 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 VolumeButton 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 VolumeButton instance.

    Declaration

    Swift

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

    Parameters

    op

    pointer to the underlying object
