Problem with disabling "ENTER" key in JTextArea

Question

Hi,
I have the following codes to disable the 'ENTER' key in the JTextArea,
but it does not work. Does anyone know why?
KeyStroke enterKey = KeyStroke.getKeyStroke(KeyEvent.VK_ENTER, 0);
textarea.getKeymap().removeKeyStrokeBinding(enterKey);
textarea.addKeyListener(new KeyAdapter() {
public void keyTyped(KeyEvent e) {
// do something
Thanks,

I don't know how you mean "disable", but if you are going to ignore the Enter key, then add a KeyListener to the text area, and in the key pressed method, consume() the key event if the VK_ENTER was pressed. That's all, and you don't have to deal with that key binding thingy.
The other two event types (typed and released) might be ignored, the enter is processed during key press (as it is now, with the default settings).
The reason is that processing the Enter key (and other such internally understood keys) is done by the peer, but the peer won't get the key event if it's already consumed.
FYI: Were it a JTextField, consuming the Enter key presses would mean that the field won't fire action events any more. Since text area does not fire action events, therefore it's a non issue.
FYI2: Consuming the event only blocks the event to be sent to the peer, all the other listeners still get it.
