All Implemented Interfaces:

ImageObserver, MenuContainer, Serializable, Runnable, Accessible

public class gz390_screen
extends JPanel
implements Runnable

The gz390_screen class defines public Graphics2D panel for use by gz390 to define GUAM views:

1. tn_screen
2. graphic_screen

The method set_screen(rows,cols,font, background_color,text_color) is used to initialize screen size based on the height and width of the font assuming it has been set to desired font size and is a monospace font. gz390 characer and graphics commands draw directly on gz390_screen buffered image object which is repainted at fixed intervals whenever scn_repaint is set true.
