+ * SECTION:hdy-view-switcher-bar
+ * @short_description: A view switcher action bar.
+ * @title: GtkHdyViewSwitcherBar
+ * @See_also: #GtkHdyViewSwitcher, #GtkHdyViewSwitcherTitle
+ *
+ * An action bar letting you switch between multiple views offered by a
+ * #GtkStack, via an #GtkHdyViewSwitcher. It is designed to be put at the bottom of
+ * a window and to be revealed only on really narrow windows e.g. on mobile
+ * phones. It can't be revealed if there are less than two pages.
+ *
+ * You can conveniently bind the #GtkHdyViewSwitcherBar:reveal property to
+ * #GtkHdyViewSwitcherTitle:title-visible to automatically reveal the view switcher
+ * bar when the title label is displayed in place of the view switcher.
+ *
+ * An example of the UI definition for a common use case:
+ * |[
+ * <object class="GtkWindow"/>
+ * <child type="titlebar">
+ * <object class="HdyHeaderBar">
+ * <property name="centering-policy">strict</property>
+ * <child type="title">
+ * <object class="GtkHdyViewSwitcherTitle"
+ * id="view_switcher_title">
+ * <property name="stack">stack</property>
+ * </object>
+ * </child>
+ * </object>
+ * </child>
+ * <child>
+ * <object class="GtkBox">
+ * <child>
+ * <object class="GtkStack" id="stack"/>
+ * </child>
+ * <child>
+ * <object class="GtkHdyViewSwitcherBar">
+ * <property name="stack">stack</property>
+ * <property name="reveal"
+ * bind-source="view_switcher_title"
+ * bind-property="title-visible"
+ * bind-flags="sync-create"/>
+ * </object>
+ * </child>
+ * </object>
+ * </child>
+ * </object>
+ * ]|
+ *
+ * # CSS nodes
+ *
+ * #GtkHdyViewSwitcherBar has a single CSS node with name viewswitcherbar.
