deprecated: 1.4

#### Description [src]

    final class Adw.ViewSwitcherTitle : Gtk.Widget
      implements Gtk.Accessible, Gtk.Buildable, Gtk.ConstraintTarget {
      /* No available fields */
    }

A view switcher title.

A widget letting you switch between multiple views contained by a `AdwViewStack` via an `AdwViewSwitcher`.

It is designed to be used as the title widget of a `AdwHeaderBar`, and will display the window’s title when the window is too narrow to fit the view switcher e.g. on mobile phones, or if there are less than two views.

In order to center the title in narrow windows, the header bar should have `AdwHeaderBar:centering-policy` set to `ADW_CENTERING_POLICY_STRICT`.

`AdwViewSwitcherTitle` is intended to be used together with `AdwViewSwitcherBar`.

A common use case is to 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, as follows:

    <object class="AdwWindow">
      <property name="content">
        <object class="AdwToolbarView">
          <child type="top">
            <object class="AdwHeaderBar">
              <property name="centering-policy">strict</property>
              <property name="title-widget">
                <object class="AdwViewSwitcherTitle" id="title">
                  <property name="stack">stack</property>
                </object>
              </property>
            </object>
          </child>
          <property name="content">
            <object class="AdwViewStack" id="stack"/>
          </property>
          <child type="bottom">
            <object class="AdwViewSwitcherBar">
              <property name="stack">stack</property>
              <binding name="reveal">
                <lookup name="title-visible">title</lookup>
              </binding>
            </object>
          </child>
        </object>
      </property>
    </object>
