old NASA style counter built from Swing components

larryfulkerson

Here's an old NASA style counter widget I built using Swing. You guys can modify this code to make a progress meter out of it if you'd like.

There's three files to this eclipse project. Here's the first file:

java code

package lgfOldStyleCounter;

import java.awt.Color;
import java.awt.Dimension;
import javax.swing.*;

/*
 * NOTE:  this counter only goes up to 99,999 and no higher
 */
public class OldStyleCounter {
	Dimension size;
	Counter c;

	public void updateValue( int i){ c.updateValue(i); }
	
	public OldStyleCounter() {

		JFrame.setDefaultLookAndFeelDecorated(false);
		
		JFrame frame = new JFrame("OldStyleCounter Test");
		size = new Dimension( 450, 190 );
	    frame.setSize(size);
	    frame.setMaximumSize(size);
	    frame.setMinimumSize(size);
	    frame.setPreferredSize(size);
	    frame.setLocation( 100,100 );
	    frame.setLayout(null);
	    c = new Counter();
	    frame.add(c);
	    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
	    frame.setBackground(Color.black);
	    frame.setVisible(true);
	} // close constructor

	public static void main(String[] args) {
		OldStyleCounter o = new OldStyleCounter();
		
		for( int i = 1; i  0 ) displayZero = true;
		element1.paintYourself( g, tenthousands, displayZero	);

		int temp = value - ( tenthousands * 10000 ); // temp holds a,bcd
		thousands = temp / 1000;
		if ( thousands > 0 ) displayZero = true;
		element2.paintYourself( g, thousands, displayZero );

		temp = temp - ( thousands * 1000 ); // temp holds 0,bcd
		hundreds = temp / 100;
		if( hundreds > 0 )  displayZero = true;
		element3.paintYourself( g, hundreds, displayZero );

		temp = temp - ( hundreds * 100) ;   // temp holds 0,0cd
		tens = temp / 10;
		
		if( tens > 0 )  displayZero = true;
		element4.paintYourself( g, tens, displayZero );

		temp = temp - ( tens * 10); // temp holds 0,00d
		ones = temp;
		displayZero = true;
		element5.paintYourself(g, ones, displayZero);
		
		g.setColor(oldColor);
	}
	
	public void run() {
		int oldValue = 32768;
		while( true) {
			//System.out.println("running");
			try {
				Thread.sleep(500);
			}
			catch( InterruptedException ie) { /**/ }
			if ( oldValue != value ) {
				repaint();
				oldValue = value;
			}
		} // close while 
	}
} // close class Counter
