### Class

# Gtk WindowControls

#### Description [src]

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

`GtkWindowControls` shows window frame controls.

Typical window frame controls are minimize, maximize and close buttons, and the window icon.

`GtkWindowControls` only displays start or end side of the controls (see `GtkWindowControls:side`), so it’s intended to be always used in pair with another `GtkWindowControls` for 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>

# CSS nodes

    windowcontrols
    ├── [image.icon]
    ├── [button.minimize]
    ├── [button.maximize]
    ╰── [button.close]

A `GtkWindowControls`‘ CSS node is 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 `GtkWindowControls:decoration-layout` value.

When `GtkWindowControls:empty` is `TRUE`, it gets the .empty style class.
