Lines in applets again.... not quite what i was looking for.

Question

ok. when i say i want it to free draw i mean not just printing lines to the screen, know how to do that. i want to use the mouse to be able to draw a line by pressing and releasing it within the applet window. ie.the pencil tool in microsoft paint.
any ideas? heres the code i've got so far. kinda stuck now though.
// import stuff
import java.applet.Applet;
import java.awt.*;
import java.awt.event.*;
//main class creation
public class PaintProg extends Applet implements MouseListener, MouseMotionListener,ActionListener {
Button scribble = new Button ( "Scribble" );
Button clear = new Button( "Clear Image" );
Choice shape_choice;
private int xLeft=10, yTop= 50, size=100;
private int x=0, y=0;
private int oldX = 0;
private int oldY = 0;
// button and menu creation
public void init()
setBackground(Color.white);
add( scribble );
add(clear);
shape_choice = new Choice();
shape_choice.addItem("Shape");
shape_choice.addItem("Square");
shape_choice.addItem("Circle");
shape_choice.addItem("Line");
add(shape_choice);
scribble.addActionListener(this);
clear.addActionListener(this);
public void paint (Graphics g) {
public void mouseClicked (MouseEvent event){
x=event.getX();
y=event.getY();
if (x>=xLeft && x<=xLeft+size && y>=yTop &&
y<=yTop+size){
repaint();
public void mouseDragged(MouseEvent event) {
int x,y;
Graphics g = getGraphics();
x = event.getX();
y = event.getY();
g.drawLine(oldX, oldY, x, y);
oldX = x;
oldY = y;
public void actionPerformed(ActionEvent evt) {
if (evt.getSource() == scribble)
{ //code to carry out actions for scribble
System.out.println("scribble");}
else if (evt.getSource() == clear)
{ //code to carry out actions for clear
System.out.println("wibble");}
else if (evt.getSource() == "Square")
{ //code to carry out actions for square
System.out.println("dribble");}
else if (evt.getSource() == "Circle")
{ //code to carry out actions for circle
else if (evt.getSource() == "Line")
{ //code to carry out actions for line
System.out.println("pibble");}
public void mouseReleased (MouseEvent event) {}
public void mousePressed (MouseEvent event) {}
public void mouseEntered (MouseEvent event) {}
public void mouseExited (MouseEvent event) {}
public void mouseMoved (MouseEvent event) {}

It's not anapplet but it will help:
