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