SpinnerRef

public struct SpinnerRef : SpinnerProtocol, GWeakCapturing

A GtkSpinner widget displays an icon-size spinning animation.

It is often used as an alternative to a [classGtk.ProgressBar] for displaying indefinite activity, instead of actual progress.

An example GtkSpinner

To start the animation, use [methodGtk.Spinner.start], to stop it use [methodGtk.Spinner.stop].

CSS nodes

GtkSpinner has a single CSS node with the name spinner. When the animation is active, the :checked pseudoclass is added to this node.

The SpinnerRef type acts as a lightweight Swift reference to an underlying GtkSpinner instance. It exposes methods that can operate on this data type through SpinnerProtocol conformance. Use SpinnerRef only as an unowned reference to an existing GtkSpinner instance.

  • ptr 
    Untyped pointer to the underlying `GtkSpinner` instance.

    For type-safe access, use the generated, typed pointer spinner_ptr property instead.
