placing/adding canvas on/to applet

[foleyflint]

Hello,
lately I've been trying to make an applet that has a background image and a couple of canvas objects on it holding an image each.
I created the class ImageCanvas which extends Canvas adn draws a picture in the canvas.
Next I have to place the canvas on the applet and there I got stuck because I don't know how to control the position of every canvas. How can I put a canvas exactly there where I want it to be?

Here is my code so far:

import java.awt.*;
import java.applet.*;
import java.awt.event.*;
import java.awt.image.*;
import java.io.*;
import java.util.*;
import java.net.*; 
import java.awt.Graphics;

public class TLCS extends Applet {
	
	Image image;
	ImageCanvas canvas1;
	Graphics g;
	
	public void init()
    { 
      setSize(774,536);
      Toolkit toolkit = Toolkit.getDefaultToolkit();
      image = toolkit.getImage("Crossing.gif");
      canvas1 = new ImageCanvas();
      canvas1.setBounds(50, 80, 39, 99);
      //setLocation(50, 100);
      
      add(canvas1);  
    }

	public void paint(Graphics g)
	{
		g.drawImage(image, 0, 0, this);
	}

}

import java.awt.Canvas;
import java.awt.Color;
import java.awt.Font;
import java.awt.Image;
import java.awt.Graphics;
import java.awt.SystemColor;
import java.awt.Toolkit;


public class ImageCanvas extends Canvas {

private Image image;
protected int width = 39;
protected int height = 99;
Image img;

public ImageCanvas() {
//this.image = image;
	setSize(39,99);
}


public void paint(Graphics g)
{
	Toolkit toolkit = Toolkit.getDefaultToolkit();
    img = toolkit.getImage("red3.gif");
	    g.drawImage(img, 0, 0, this);
}
}

The applet does work: it displays the background image "crossing.g if" and in the center of the window it place the Canvas, but I want to have some more canvasses and place them where I want them.
Thank you,
Andre

If you had used Swing instead (a JApplet versus an Applet etc.) you could've
used a JLayeredPane; it's a nice component where other componenents (such
as JPanels (instead of a Canvas) can 'float' around on top of each other and
behind each other depending on the 'layer' the JPanel is put in.

AWT is very outdated; consider using Swing instead; the transition doesn't cost much.

kind regards,

Jos

Thank you, but I just started working with applets for the first time and finally got to understand something about a Canvas and Applet so if I have to switch I will have to do all my research all over again. My professor told me it would be the easiest way for me if I just used Applet and Canvas, because the result doesn't have to be very fancy.
I've already done pretty much and only need to know how to position a Canvas, and the rest of the programming would be what I already know.

Hey man could u have aloook at mine im not sure how to add the second image i can only get the one to pop up
import javax.swing.*;
import java.awt.*;
public class BackUp
{
public static void main(String args [])
{
JFrame jf1 = new JFrame("This Is the First Frame");
JLabel lbl1 = new JLabel();
JLabel lbl2 = new JLabel();


jf1.setSize(500 ,500);
Container c = jf1.getContentP ane();


ImageIcon icon = new ImageIcon("Golf .jpg");
lbl1.setIcon(ic on);

c.add(lbl1);

ImageIcon icon2 = new ImageIcon("golf ball.jpg");
lbl2.setIcon(ic on2);



c.add(lbl2);
c.add(lbl1);

jf1.setVisible( true);



}
}

1.) Hijacking is bad
2.) Code tags are good.
3.) Using a layout manager is sweet.
