Java Swing JButton keyboard shortcuts

It took ages to work out how to do this, so I decided to post it here in the hope someone else will benefit. Here's how to install a keyboard shortcut to a a Swing JButton so the button behaves as though it was clicked when the key is pressed:

JButton saveButton = new JButton(new SaveAction());
InputMap inputMap = saveButton.getInputMap(JButton.WHEN_IN_FOCUSED_WINDOW);
KeyStroke enter = KeyStroke.getKeyStroke(KeyEvent.VK_ENTER, 0);
inputMap.put(enter, "ENTER");
saveButton.getActionMap().put("ENTER", new ClickAction(saveButton));


public class ClickAction extends AbstractAction {
private JButton button;

public ClickAction(JButton button) {
this.button = button;

public void actionPerformed(ActionEvent e) {

A complete example is in shortcut-buttons-src-0.1.jar. The download includes an ant build file. To compile and run, just type "ant run" at the shell prompt. You will need ant and a JDK >= 1.5 installed.
