Class
AdwHeaderBar
Description [src]
final class Adw.HeaderBar : Gtk.Widget {
  /* No available fields */
}A title bar widget.
 
AdwHeaderBar is similar to GtkHeaderBar, but provides additional
features compared to it. Refer to GtkHeaderBar for details.
AdwHeaderBar:centering-policy allows to enforce strict centering of
the title widget, this is useful for AdwViewSwitcherTitle.
AdwHeaderBar:show-start-title-buttons and
AdwHeaderBar:show-end-title-buttons allow to easily create split
header bar layouts using AdwLeaflet, as follows:
<object class="AdwLeaflet" id="leaflet">
  <child>
    <object class="GtkBox">
      <property name="orientation">vertical</property>
      <child>
        <object class="AdwHeaderBar">
          <binding name="show-end-title-buttons">
            <lookup name="folded">leaflet</lookup>
          </binding>
        </object>
      </child>
      <!-- ... -->
    </object>
  </child>
  <!-- ... -->
  <child>
    <object class="GtkBox">
      <property name="orientation">vertical</property>
      <property name="hexpand">True</property>
      <child>
        <object class="AdwHeaderBar">
          <binding name="show-start-title-buttons">
            <lookup name="folded">leaflet</lookup>
          </binding>
        </object>
      </child>
      <!-- ... -->
    </object>
  </child>
</object>

AdwHeaderBar‘s CSS node is called headerbar. It contains a windowhandle
subnode, which contains a box subnode, which contains two widget subnodes
at the start and end of the header bar, each of which contains a box
subnode with the .start and .end style classes respectively, as well as a

Each of the boxes contains a windowcontrols subnode, see
