public void keyPressed(KeyEvent e) {
if (e.getKeyCode() == KeyEvent.VK_DOWN) {

adjustLayout();
}

Make sure that you are adding the KeyListener to the component that will have the focus.

JPanel pnl = new JPanel();
pnl.addKeyListener(new KeyListener() {
  public void keyPressed(KeyEvent e) {
    // ...
  }
  public void keyReleased(KeyEvent e) {
    // ...
  }
  public void keyTyped(KeyEvent e) {
    // ...
  }
});

Hope this helps.
