view-switcher-bar

An action bar letting you switch between multiple views contained in a ViewStack, via an ViewSwitcher. 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.

AdwViewSwitcherBar is intended to be used together with AdwViewSwitcher in a header bar, and a Breakpoint showing the view switcher bar on narrow sizes, while removing the view switcher from the header bar, as follows: 

<object class="AdwWindow">
   <child>
     <object class="AdwBreakpoint">
       <condition>max-width: 550sp</condition>
       <setter object="switcher_bar" property="reveal">True</setter>
       <setter object="header_bar" property="title-widget"/>
     </object>
   </child>
   <property name="content">
     <object class="AdwToolbarView">
       <child type="top">
         <object class="AdwHeaderBar" id="header_bar">
           <property name="title-widget">
             <object class="AdwViewSwitcher">
               <property name="stack">stack</property>
               <property name="policy">wide</property>
             </object>
           </property>
         </object>
       </child>
       <property name="content">
         <object class="AdwViewStack" id="stack"/>
       </property>
       <child type="bottom">
         <object class="AdwViewSwitcherBar" id="switcher_bar">
           <property name="stack">stack</property>
         </object>
       </child>
     </object>
   </property>
 </object>

It's recommended to set ViewSwitcher:policy to ADW_VIEW_SWITCHER_POLICY_WIDE in this case.

You may have to adjust the breakpoint condition for your specific pages.
