Accelerator / Shortcut

Question

How do I add an accelerator key (or shortcut) to a button on a Java Dialog (swing)? I haven't seen an example of this and it seems like it shouldn't be that tough... Any ideas?

youll notice KeyEvent inherits isAltDown() from input event
you can have your class implement KeyListener and then override
public void keyPressed(KeyEvent e) {
if( e.isAltDown() == true ){
do();
public void keyTyped(KeyEvent e) {}
public void keyReleased(KeyEvent e) {}
or add a KeyStroke action:
KeyStroke ent = KeyStroke.getKeyStroke(KeyEvent.VK_ENTER, 0, false);
Action entAction = new AbstractAction()
public void actionPerformed(ActionEvent e)
if(  ){
do();
getRootPane().getInputMap(JComponent.WHEN_IN_FOCUSED_WINDOW).put(ent, "ENTER");
getRootPane().getActionMap().put("ENTER", entAction);
