[JAVA3D] KeyListener

[Patrik M�ller]

Hi all

 

I have a problem with the KeyListener. It does not work. The System.out.println("xyz " + e) is never coming. Why?

My Code is like this:

 

 

package xy;

 

import java.awt.*;
import java.awt.event.*;
import java.awt.GraphicsConfiguration;

 

import javax.swing.*;
import javax.swing.event.*;
import javax.media.j3d.*;
import javax.vecmath.*;

 

import com.sun.j3d.utils.applet.MainFrame;
import com.sun.j3d.utils.image.TextureLoader;
import com.sun.j3d.utils.universe.*;
import com.sun.j3d.utils.picking.behaviors.*;
import com.sun.j3d.utils.behaviors.mouse.*;
import com.sun.j3d.utils.picking.*;

 

 

 

public class zzz extends JFrame implements KeyListener {

 

...

...

 /**
  * handles the events generated by pressing a key
  */
 public void keyPressed(KeyEvent e){
   System.out.println("keyPressed " + e);

 

 }

 

 /**
  * handles the events generated by typing a key
  */
 public void keyTyped(KeyEvent e) {
  System.out.println("keyTyped " + e);
 }

 

 /**
  * handles the events generated by releasing a key
  */
 public void keyReleased(KeyEvent e){
  System.out.println("keyReleased " + e);
 }

 

} // end of class
