### Class

# AdwViewSwitcherBar

#### Description [src]

    final class Adw.ViewSwitcherBar : Gtk.Widget {
      /* No available fields */
    }

A view switcher action bar.

An action bar letting you switch between multiple views contained in a `AdwViewStack`, via an `AdwViewSwitcher`. 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 `AdwViewSwitcherBar:reveal` property to `AdwViewSwitcherTitle: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="AdwHeaderBar">
          <property name="centering-policy">strict</property>
          <child type="title">
            <object class="AdwViewSwitcherTitle" id="title">
              <property name="stack">stack</property>
            </object>
          </child>
        </object>
      </child>
      <child>
        <object class="GtkBox">
          <child>
            <object class="AdwViewStack" id="stack"/>
          </child>
          <child>
            <object class="AdwViewSwitcherBar">
              <property name="stack">stack</property>
              <binding name="reveal">
                <lookup name="title-visible">title</lookup>
              </binding>
            </object>
          </child>
        </object>
      </child>
    </object>
