Managing the layout of a Java MainFrame of Canvas3d

Question

Hi, Im trying to organise the layout of four canvas3d objects in a single MainFrame. Iv tried using some layout managers but none are working (or im doing it wrong). Can anyone give me advice or point me to a way to get this to display the four canvas's as a grid of four?

Thanks,

John

public class Main {

        public static void Main(){
            Window win = new Window();
        }
}
