+Spinner
+=======
+
+The :class:`Gtk.Spinner` displays an icon-size spinning animation.
+It is often used as an alternative to a :class:`GtkProgressBar`
+for displaying indefinite activity, instead of actual progress.
+
+To start the animation, use :meth:`Gtk.Spinner.start`,
+to stop it use :meth:`Gtk.Spinner.stop`.
