Auto Image Display code debugging

[Paddy Notemaker]

Dear all,

I have been working on a java applet that is supposed to automatically display images that are named 1,2,3,etc to the last image. Basically I have a few methods that deal with increasing x (the number) in increments of 1, and a couple more that deal with adding file extensions etc. Basically, the user is supposed to be able to use the arrow keys to alter the x value, right being a positive increase and left being a negative increase. I just cannot see why it is not working. Any help with this code would be great.

Code
----------------------------------------------------------------------

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

public class catalogue extends JApplet
{

private int x = 1;
String filexten = ".gif";
String filename = x + filexten ;
public Image picture;

public void init()
{
JRootPane rootPane = this.getRootPane();
rootPane.putClientProperty("defeatSystemEventQueueCheck,Boolean.TRUE);
}
public void start() {}
public void stop() {}
public boolean keyDown(Event e, int key)
{
if(key == Event.LEFT)
{
x--;
}
if(key == Event.RIGHT)
{
x++;
}
if(key == Event.DOWN)
{
x = 1;
}
return true;
}
public String filename()
{
return x + filexten;
}
public void update(Graphics g)
{
String filexten = ".gif";
String filename = x + filexten ;
picture=getImage(getDocumentBase(),"filename()");
if (picture == null)
{
g.drawImage(picture,0,0,this);
}
g.drawImage(picture,0,0,this);
}
public void run() {}

}

----------------------------------------------------------------------
End Code

Thanks to all.

Go back and compare to your Animator class that used an almost identical IO. It seems you're just not hooked into the events at all here.
