ScaleButton
open class ScaleButton : Widget, ScaleButtonProtocol
GtkScaleButton
provides a button which pops up a scale widget.
This kind of widget is commonly used for volume controls in multimedia
applications, and GTK provides a [classGtk.VolumeButton
] subclass that
is tailored for this use case.
CSS nodes
GtkScaleButton
has a single CSS node with name button. To differentiate
it from a plain GtkButton
, it gets the .scale style class.
The ScaleButton
type acts as a reference-counted owner of an underlying GtkScaleButton
instance.
It provides the methods that can operate on this data type through ScaleButtonProtocol
conformance.
Use ScaleButton
as a strong reference or owner of a GtkScaleButton
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
ScaleButton
instance.Declaration
Swift
@inlinable public init(_ op: UnsafeMutablePointer<GtkScaleButton>)
Parameters
op
pointer to the underlying object
-
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 theScaleButton
instance.Declaration
Swift
@inlinable public init(_ op: UnsafePointer<GtkScaleButton>)
Parameters
op
pointer to the underlying object
-
Optional initialiser from a non-mutating
gpointer
to the underlyingC
data type. This creates an instance without performing an unbalanced retain i.e., ownership is transferred to theScaleButton
instance.Declaration
Swift
@inlinable override public init!(gpointer op: gpointer?)
Parameters
op
gpointer to the underlying object
-
Optional initialiser from a non-mutating
gconstpointer
to the underlyingC
data type. This creates an instance without performing an unbalanced retain i.e., ownership is transferred to theScaleButton
instance.Declaration
Swift
@inlinable override public init!(gconstpointer op: gconstpointer?)
Parameters
op
pointer to the underlying object
-
Optional 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 theScaleButton
instance.Declaration
Swift
@inlinable public init!(_ op: UnsafePointer<GtkScaleButton>?)
Parameters
op
pointer to the underlying object
-
Optional initialiser from the underlying
C
data type. This creates an instance without performing an unbalanced retain i.e., ownership is transferred to theScaleButton
instance.Declaration
Swift
@inlinable public init!(_ op: UnsafeMutablePointer<GtkScaleButton>?)
Parameters
op
pointer to the underlying object
-
Designated initialiser from the underlying
C
data type. Will retainGtkScaleButton
. i.e., ownership is transferred to theScaleButton
instance.Declaration
Swift
@inlinable public init(retaining op: UnsafeMutablePointer<GtkScaleButton>)
Parameters
op
pointer to the underlying object
-
Reference intialiser for a related type that implements
ScaleButtonProtocol
Will retainGtkScaleButton
.Declaration
Swift
@inlinable public init<T>(scaleButton other: T) where T : ScaleButtonProtocol
