/*!

    A message-only window enables you to send and receive messages. It is not visible, has no z-order, cannot be enumerated, and does not
    receive broadcast messages. The window simply dispatches messages.

    A MessageWindow do not have any builder parameter, but still provides the API for the derive macro.

    Requires the `message-window` feature. 

    ## Example
    ```
    use native_windows_gui as nwg;

    let mut window = Default::default();
    nwg::MessageWindow::builder().build(&mut window);
    ```

    When making a system-tray application (with TrayNotification), this is the recommended top level window type.
