Hi All

A very new newbie to Java so please be gentle with me.

I have some code that I have cobbled together from various sources on
the web (Thanks to all those whose source has helped me get this far).
I am attempting to write a small test application using MVC which will
open a small window and display an image as a background and then
allow me to move an object around using the keyboard..

I have the code below which opens a window in the middle of the
screen. However, I do not know how to attach the image (img) to the
panel (jpanel).

There are several possibilities. One is to introduce a JPanel which is
able to draw a background image. E.g. something like this

public class BackgroundPanel extends JPanel {

     private Image img;

     public void setImage(Image img) {
         this.img = img;
     }

     protected void paintComponent(Graphics g) {
         if ( img != null )
             g.drawImage(img, 0, 0, this);
     }
}

Bye
Michael
