<p>A GtkSpinner widget displays an icon-size spinning animation.
It is often used as an alternative to a <a class="link" href="GtkProgressBar.html" title="GtkProgressBar"><span class="type">GtkProgressBar</span></a> for
displaying indefinite activity, instead of actual progress.</p>
<p>To start the animation, use <a class="link" href="GtkSpinner.html#gtk-spinner-start" title="gtk_spinner_start ()"><code class="function">gtk_spinner_start()</code></a>, to stop it
use <a class="link" href="GtkSpinner.html#gtk-spinner-stop" title="gtk_spinner_stop ()"><code class="function">gtk_spinner_stop()</code></a>.</p>
