The gtk:window-controls widget shows window frame controls, such as Minimize, Maximize and Close buttons, and the window icon.

Figure: GtkWindowControls

The gtk:window-controls widget only displays start or end side of the controls, see the side property, so it is intended to be always used in pair with another gtk:window-controls widget using the opposite side, for example:

<object class="GtkBox">
  <child>
    <object class="GtkWindowControls">
      <property name="side">start</property>
    </object>
  </child>
  ...
  <child>
    <object class="GtkWindowControls">
      <property name="side">end</property>
    </object>
  </child>
</object>

The gtk:window-controls implementation has a CSS node called windowcontrols. It contains subnodes corresponding to each title button. Which of the title buttons exist and where they are placed exactly depends on the desktop environment and the decoration-layout property. When the empty property is true, it gets the .empty style class. The gtk:window-controls implementation uses the :group role.
