Java key listener help

[pants18]

I have a piece of code below from my program and I'm trying to set up a key listener so that when the keys right, left, up, and down are pressed, it removes the corresponding jbutton (_b1, _b2, etc) from the jpanel (_panel). I'm not getting any compilation errors and the bottom section of the if statement does indeed remove the jbutton, I just need help as to how to implement the key listener prior to that.

 

public void keyPressed(KeyEvent e) {

 

   int key = e.getKeyCode();

 

   if (key == KeyEvent.VK_LEFT) {

       _panel.remove(_b1);

   }

 

   if (key == KeyEvent.VK_RIGHT) {

    _panel.remove(_b2);

   }

 

   if (key == KeyEvent.VK_UP) {

    _panel.remove(_b3);

   }

 

   if (key == KeyEvent.VK_DOWN) {

    _panel.remove(_b4);

   }

 

}

Have you added the keylistener to the jpanel? If not, in your creation of the window code add this line:

_panel.addKeyListener()

just put in the brackets the instance of the keylistener
