HANDLING MOUSE EVENTS

  Listeners are created by using one or more of the interfaces defined by the java.awt.event package.

   Example:

import java.awt.event.*;

import java.applet.*;

import java.awt.*;

public class MyEventApplet extends Applet implements MouseListener, MouseMotionListener

{

 String msg="";

 int x,y;

 public void init()

 {

  x=y=0;

  addMouseListener(this);

  addMouseMotionListener(this);

 }

 public void paint(Graphics g)

 {

  g.drawString(msg,x,y);

 }

 public void mouseClicked(MouseEvent e)

 {

  x=e.getX();

  y=e.getY();

  msg="Mouse Clicked";

 }

 public void mousePressed(MouseEvent e)

 {

  x=e.getX();

  y=e.getY();

  msg="Mouse Pressed";

 }

 public void mouseReleased(MouseEvent e)

 {

  x=e.getX();

  y=e.getY();

  msg="Mouse Released";

 }

 public void mouseMoved(MouseEvent e)

 {

  x=e.getX();

  y=e.getY();

  showStatus("Mouse Moved at "+x+" , "+y);

  repaint();

 }

 public void mouseDragged(MouseEvent e)

 {

  x=e.getX();

  y=e.getY();

  showStatus("Mouse Dragged at "+x+" , "+y);

  repaint();

 }

 public void mouseExited(MouseEvent e)

 {

  x=0;

  y=10;

  msg="Mouse exited";

  repaint();

 }

 public void mouseEntered(MouseEvent e)

 {

  x=0;

  y=10;

  msg="Mouse exited";

  repaint();

 }

} 

OUTPUT:

In the above example, Listener are created for various mouse related events that handles the appropriate event generated by the event.
