Java：如何更改setDefaultButton（）的激活事件键？

Question

Is there a way to change the default activation event key for setDefaultButton()? The default key is ENTER .

This is the scenario: In login window, there's two(2) button, one is for login and the other is exit. Setting login button to setDefaultButton() is a good idea but I would like to have another activation event key which is ESCAPE to respond with exit button.

Thanks!

this is what you should do

InputMap inputMap = panel.getInputMap(JComponent.WHEN_ANCESTOR_OF_FOCUSED_COMPONENT);
inputMap.put(KeyStroke.getKeyStroke(KeyEvent.VK_ESCAPE, 0), "exitAction");
panel.getActionMap().put("exitAction", exitAction);

Action exitAction = new AbstractAction() {
        public void actionPerformed(ActionEvent e) {
            //what ever happen on exit goes here
        }
    };
