I'm having some difficulties in applying the ToolTips functions in a
graphic program in java.

I was trying to make my canvas inherit the functions of ToolTip, to
when the mouse move over the draw area, appear a "tip" on the side of
the mouse, showing a text.
I already try a lot of things and nothing sens to work, I'm thinking
in do it manually. But I prefer to use the ToolTip package.
The sites that I'm using are:

This last one is perfect to what I want, because it controls when and
how the tip is show. But I'm can't implement it at all.

Can somebody send me a example where its implemented?
Or a link to a tutorial?
Or modify this code to show me how it's done:

import java.applet.Applet;
import java.awt.Graphics;

public class Teste01 extends Applet{

    public void init(){

    public void paint(Graphics g){
        g.drawRect(10, 10, 50, 50);

Thanks in advance.

Tooltips are built in to Swing components. Why don't you use a JApplet
and a JPanel instead of the Applet and Canvas?

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;

public class test extends JApplet {
     public void init() {
         JPanel p = new JPanel();
         p.setPreferredSize(new Dimension(100,75));
         p.setToolTipText("My Blue JPanel");

     public static void main(String[] args) {
         EventQueue.invokeLater(new Runnable() {
             public void run() {
                 JFrame f = new JFrame();
                 test t = new test();
