    /// A [`Window`][crate::Window] is a toplevel window which can contain other widgets.

    ///
    /// # 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

    /// ├── <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

    ///

    /// Generally, some CSS properties don't make sense on the toplevel window node,
