How to create hot key?

Hi all,

I'm creating an application by using the J2SE v 1.4.2_10 SDK with NetBeans 4.1 Bundle. I have created 4 button and handles event each. I would like to create a hotkey for each button, "F2" key for jButtton2, "F3" key for jButton3, "F8" key for jButton4, "F1" key for jButton5, once i click on the key, the event will be triggered and the coding inside will be executed.

Actually I have read through a few includingHow to Write a Key Listener, How to Write a Component Listener, How to Write an Action Listener, How to Use Actions, How to Use Key Bindings... but i really not so clear about that and don't know how to apply that into my task... Hope someone can help me...Thanks

The following is part of my coding...

Use the Action architecture (http://java.sun.com/products/jfc/tsc/articles/actions/):

import java.awt.event.ActionEvent;

import javax.swing.AbstractAction;

import javax.swing.Action;

import javax.swing.JButton;

import javax.swing.JFrame;

import javax.swing.JPanel;

import javax.swing.KeyStroke;

public class HotKeyComponent extends JPanel {

public static void main(String[] args) {

HotKeyComponent c = new HotKeyComponent();

UselessAction a1 = new UselessAction("Action 1", "action.1", KeyStroke.getKeyStroke("F1"));

UselessAction a2 = new UselessAction("Action 2", "action.2", KeyStroke.getKeyStroke("F2"));

UselessAction a3 = new UselessAction("Action 3", "action.3", KeyStroke.getKeyStroke("F4"));

c.addButton(a1);

c.addButton(a2);

c.addButton(a3);

JFrame frame = new JFrame("HotKey Test");

frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

frame.setBounds(100, 100, 400, 300);

frame.add(c);

frame.setVisible(true);

}

public void addButton(Action action) {

Object command = action.getValue(Action.ACTION_COMMAND_KEY);

KeyStroke stroke = (KeyStroke)action.getValue(Action.ACCELERATOR_KEY);

getInputMap(WHEN_ANCESTOR_OF_FOCUSED_COMPONENT).put(stroke, command);

getActionMap().put(command, action);

JButton button = new JButton(action);

add(button);

}

static class UselessAction extends AbstractAction {

public UselessAction(String name, Object actionCommand, KeyStroke stroke) {

putValue(Action.NAME, name);

putValue(Action.ACTION_COMMAND_KEY, actionCommand);

putValue(Action.ACCELERATOR_KEY, stroke);

}

public void actionPerformed(ActionEvent actionEvent) {

System.out.println("actionPerformed " + getValue(Action.NAME));

}

}

}

The example contains three buttons. You can either click them, or press the key which is mapped to an Action.
