ScaleButtonRef
public struct ScaleButtonRef : ScaleButtonProtocol, GWeakCapturing
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 ScaleButtonRef
type acts as a lightweight Swift reference to an underlying GtkScaleButton
instance.
It exposes methods that can operate on this data type through ScaleButtonProtocol
conformance.
Use ScaleButtonRef
only as an unowned
reference to an existing GtkScaleButton
instance.
-
Untyped pointer to the underlying `GtkScaleButton` instance.
For type-safe access, use the generated, typed pointer
scale_button_ptr
property instead.Declaration
