A gtk.spinner.Spinner widget displays an icon-size spinning animation.
It is often used as an alternative to a gtk.progress_bar.ProgressBar for displaying indefinite activity, instead of actual progress.
To start the animation, use gtk.spinner.Spinner.start, to stop it use gtk.spinner.Spinner.stop.
gtk.spinner.Spinner has a single CSS node with the name spinner. When the animation is active, the :checked pseudoclass is added to this node.
