Hi:

I've worked with KeyEvents and MouseEvents using JTextField and they work
perfectly. Here is the code I use:

void keyPressed(KeyEvent e)
  {
   int k = e.getKeyCode();

    switch (k)
    {
     case KeyEvent.VK_DELETE: //Delete code here
                                                    reset();
                                                    e.setKeyCode(0);
                                                    return;
     case KeyEvent.VK_ENTER:  //Enter pressed
                                                   return;
     case KeyEvent.VK_UP:        //up-arrow
    }
}
