    Default Key events and key listeners

    Hello again folks. Having trouble with this one. I want to update my JTextArea when a key is presses. Here's a snippet of my code:

    Java Code:
        private JTextField myText;
    
        public MyGui()
        {
            ad = new KeyWatcher();
            setFocusable(true);
    
            setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
            myText = new JTextField(20);
            myText.addKeyListener(ad);
      
    		private class KeyWatcher extends KeyAdapter
        {
            @Override
            public void keyPressed(KeyEvent k)
            {
               {
                myText.setText(k.getKeyChar()+"");
                System.out.println(myText);
               }
            }
        }
    }
    Nothing happens when I run it. I want it to print out the value of the key(s) I've pressed. I've gone over the API about a million times but can't see where I'm going wrong. Can you help?

    Thanks in advance.

    Default Re: Key events and key listeners

    You're not showing the relevant code, i.e. where do you add your JTextField to your JFrame?

    kind regards,

    Jos
