Dynamic/Onspot JTextfield to JLabel

Question

I want to make a pair JTextField/JLabel work as here on StackOverflow, I mean that I want a string to be displayed in JLabel as I write it in JTextField.

I tried adding ActionListener to JTextField but it works only for ENTER. Any ideas?

@calderon: please delete your comment as it is most definitely the wrong approach (as mKorbel has already pointed out. Much better to use a DocumentListener as Joe (1+) suggests as this will capture copy-pastes as well. — Hovercraft Full Of Eels, Nov 02 '12 at 20:08

The DocumentListener should allow you receive updates from a changing text field. I think you just need to override the changeUpdate method. Good luck!
