What is lightweight and heavyweight ? how to create my applet lightweight?

Question

Sir ,
t have created an applet and in that i have not use any component
for drawing now i want to use component for applet but cant grtting how to do this , by reference of sun java i have found this code for application to create lightweight::
import java.awt.*;
import java.awt.event.*;
* Silly Sample program which demonstrates the basic paint
* callback mechanism in the AWT.
public class test1{
public static void main(String[] args) {
Frame f = new Frame("Have a nice day!");
f.addWindowListener(new WindowAdapter() {
public void windowClosing(WindowEvent e) {
System.exit(0);
f.add(new SmileyCanvas(Color.yellow), BorderLayout.CENTER);
f.pack();
f.show();
* A canvas which renders a smiley-face to the screen
* Note: Canvas is a heavyweight superclass, which makes
* SmileyCanvas also heavyweight. To convert this class to
* a lightweight, change "extends Canvas" to "extends Component".
class SmileyCanvas extends Canvas {
public SmileyCanvas(Color faceColor) {
setForeground(faceColor);
public Dimension getPreferredSize() {
return new Dimension(300,300);
* Paint when the AWT tells us to...
public void paint(Graphics g) {
// Dynamically calculate size information
// (the canvas may have been resized externally...)
Dimension size = getSize();
int d = Math.min(size.width, size.height); // diameter
int ed = d/20; // eye diameter
int x = (size.width - d)/2;
int y = (size.height - d)/2;
// draw head (color already set to foreground)
g.fillOval(x, y, d, d);
g.setColor(Color.black);
g.drawOval(x, y, d, d);
// draw eyes
g.fillOval(x+d/3-(ed/2), y+d/3-(ed/2), ed, ed);
g.fillOval(x+(2*(d/3))-(ed/2), y+d/3-(ed/2), ed, ed);
//draw mouth
g.drawArc(x+d/4, y+2*(d/5), d/2, d/3, 0, -180);
this code is not for applet so how to make this code for applet ?

Answer 1

I use the Snippets folder to store re-usable code. Scroll to
the file or
folder desired, double click and voila! Code is inserted into
the page.
As for the other bells & whistles, you are probably
thinking about DW
Extensions (.mxp) files. There are many 3rd party makers of
extensions.
Some are free, some cost a nominal fee. Check around to see
if what you
want isn't already available. If not, read this article.
