KeyListener problems - wont' work?

Hi all,

I can't get this keylistener working... my jTextField does not change when I press keys while jButton1 has focus. Can anyone tell me what the heck I'm doing wrong? I've tried many different solutions, but nothing has worked.

Hmmm, I used the NetBeans interface (right-click -> events -> keyreleased), and coded inside the method it created for me, and it works. Wonder what I was doing wrong? Oh, well...

It looks a bit as if you're adding the key listener before the components get initialized - try doing it afterwards.

You're saying, before my JButton and JTextFields are initialized?

No, afterwards. It's not clear what's going on in the code because just about everything related to creating the GUI is missing, but I'm assuming that the "initComponents" method initializes the GUI. Note how the event listener is added before that (which also means that "jButton1" must have been created even before that, or you would have gotten a NullPointerException).

Ah, OK, got it. Thank you!
