Class RobotUIComponents

java.lang.Object
  becker.robots.RobotUIComponents

public class RobotUIComponents
extends Object

A factory object that provides the major user interface components, making customized user interfaces easy to create.

For example, CityFrame has the controls on the left side rather than the right. Other, less trivial changes, are also possible.

                CityFrame cf = new CityFrame(c, -1, -2, 4, 5);
