    ///
    /// # GtkWindow as GtkBuildable
    ///
    /// The [`Window`][crate::Window] implementation of the [`Buildable`][crate::Buildable] interface supports
    /// setting a child as the titlebar by specifying “titlebar” as the “type”
    /// attribute of a `<child>` element.

    /// # CSS nodes
    ///
    /// ```text
    /// window.background [.csd / .solid-csd / .ssd] [.maximized / .fullscreen / .tiled]
    /// ├── <child>
    /// ╰── <titlebar child>.titlebar [.default-decoration]
    /// ```
    ///
    /// [`Window`][crate::Window] has a main CSS node with name window and style class .background.
    ///
    /// Style classes that are typically used with the main CSS node are .csd (when
    /// client-side decorations are in use), .solid-csd (for client-side decorations
    /// without invisible borders), .ssd (used by mutter when rendering server-side
    /// decorations). GtkWindow also represents window states with the following
    /// style classes on the main node: .maximized, .fullscreen, .tiled (when supported,
    /// also .tiled-top, .tiled-left, .tiled-right, .tiled-bottom).
    ///
    /// [`Window`][crate::Window] subclasses often add their own discriminating style classes,
    /// such as .dialog, .popup or .tooltip.
    ///
    /// Generally, some CSS properties don't make sense on the toplevel window node,
    /// such as margins or padding. When client-side decorations without invisible
    /// borders are in use (i.e. the .solid-csd style class is added to the
