VolumeButtonRef
public struct VolumeButtonRef : VolumeButtonProtocol, GWeakCapturing
GtkVolumeButton is a GtkScaleButton subclass tailored for
volume control.

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.
-
Untyped pointer to the underlying `GtkVolumeButton` instance.For type-safe access, use the generated, typed pointer
volume_button_ptrproperty instead.Declaration
Swift
public let ptr: UnsafeMutableRawPointer!
-
Designated initialiser from the underlying
Cdata typeDeclaration
Swift
@inlinable init(_ p: UnsafeMutablePointer<GtkVolumeButton>) -
Designated initialiser from a constant pointer to the underlying
Cdata typeDeclaration
Swift
@inlinable init(_ p: UnsafePointer<GtkVolumeButton>) -
Conditional initialiser from an optional pointer to the underlying
Cdata typeDeclaration
Swift
@inlinable init!(_ maybePointer: UnsafeMutablePointer<GtkVolumeButton>?) -
Conditional initialiser from an optional, non-mutable pointer to the underlying
Cdata typeDeclaration
Swift
@inlinable init!(_ maybePointer: UnsafePointer<GtkVolumeButton>?) -
Conditional initialiser from an optional
gpointerDeclaration
Swift
@inlinable init!(gpointer g: gpointer?) -
Conditional initialiser from an optional, non-mutable
gconstpointerDeclaration
Swift
@inlinable init!(gconstpointer g: gconstpointer?) -
Reference intialiser for a related type that implements
VolumeButtonProtocolDeclaration
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`.The button has 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 [class
Gtk.ScaleButton].Declaration
Swift
