    /// GtkWindow has a main CSS node with name window and style class .background,

    ///
    ///
    ///
    /// #### `delete-event`
    ///  The ::delete-event signal is emitted if a user requests that
    /// a toplevel window is closed. The default handler for this signal

    ///
    /// #### `destroy`
    ///  Signals that all holders of a reference to the widget should release
