Capture ENTER KeyEvent and Do a Click instead

Question

I have added ENTER Key to the default FocusTraversalKeys as such...

private void focus() {
    Set forwardKeys = getFocusTraversalKeys(KeyboardFocusManager.FORWARD_TRAVERSAL_KEYS);
    Set newForwardKeys = new java.util.HashSet(forwardKeys);
    newForwardKeys.add(KeyStroke.getKeyStroke(KeyEvent.VK_ENTER, 0));
    setFocusTraversalKeys(KeyboardFocusManager.FORWARD_TRAVERSAL_KEYS, newForwardKeys);
}

I have a Product Information form that I am going through using the focus but when it comes to a save button I would like to CLICK the button instead of the focus going to the next component.

I have added a KeyPressed and KeyReleased listener to the button and then tried this...

private void saveButtonKeyPressed(java.awt.event.KeyEvent evt) {                                      
    if (evt.getKeyCode() == java.awt.event.KeyEvent.VK_ENTER) {
        evt.consume();
        saveButton.doClick();
    }
}

This same method works on my Text Area BUT the code doesn't do the CLICK instead puts the focus on next component which is also a button.

Please suggest something that would help me achieve the required result. Find below the Image of the form used.

You could set the focus transferal keys for the button to be default (ie `TAB`), meaning that the `ENTER` key will perform as default... — MadProgrammer, Jun 23 '13 at 23:44
@MadProgrammer That is what I have done already, set Focus Traversal Key of everything in that Frame to include ENTER Key. I want to do "Space bar" effect when it comes to the Button and not transfer Focus to next component. — HMH, Jun 24 '13 at 12:47
You can set the focus transfer keys for an individual component as well. Have a look at the [answer by kleo](http://docs.oracle.com/javase/7/docs/technotes/guides/jweb/packagingAppsForMac.html) for more details — MadProgrammer, Jun 24 '13 at 20:46

Don't use a KeyListener. Swing was designed to be used with Key Bindings.

Check out Enter Key and Button for some solutions, one using key bindings and the other using a different approach.

Tried using the DefaultButtonListener class in the link you gave but it didn't help. – HMH Jun 24 '13 at 12:48

Removed the ENTER Key from the SET i defined when button gains Focus and thus it works with the KeyReleased Method now.

private void saveButtonFocusGained(java.awt.event.FocusEvent evt) {                                       
    newForwardKeys.remove(KeyStroke.getKeyStroke(KeyEvent.VK_ENTER, 0));  
    setFocusTraversalKeys(KeyboardFocusManager.FORWARD_TRAVERSAL_KEYS, newForwardKeys);
}

Thank you everyone for your help!
