- * SECTION:hildon-vvolumebar
- * @short_description: A widget that displays a vertical volume bar.
- * @see_also: #HildonVolumebar, #HildonHVolumebar
- *
- * #HildonVVolumebar is a subclass of #HildonVolumebar. It displays a
- * vertical volume bar that allows increasing or decreasing volume
- * within a predefined range, and muting when users click the mute icon.
- *
- * <note>
- * <para>
- * #HildonVVolumebar has been deprecated since Hildon 2.2 and should not
- * be used in newly written code. See
- * <link linkend="hildon-migrating-volume-bar">Migrating Volume Bars</link>
- * section to know how to migrate this deprecated widget.
- * </para>
- * </note>
- *
- * Here is an example that creates a vertical volume bar and connects
- * both its signals.
- *
- * <example>
- * <title>HildonVVolumebar example</title>
- * <programlisting>
- * GtkWidget *volbar = hildon_vvolumebar_new ();
- * g_signal_connect (G_OBJECT (volbar), "mute_toggled", G_CALLBACK (mute_toggle), NULL);
- * g_signal_connect (G_OBJECT (volbar), "level_changed", G_CALLBACK (level_change), NULL);
- * </programlisting>
- * </example>
