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.
