All Implemented Interfaces:

ActionListener, ImageObserver, MenuContainer, Serializable, EventListener, Accessible, TitleUpdatedListener

public class SimpleCLIPanel
extends ScriptingPanel
implements ActionListener

Creates a very simple command line for invoking the main method of classes. System.out and System.err are redirected to an output area. Features a simple command history -- use up and down arrows to move through previous commmands. This gui uses only AWT (i.e. no Swing).
