Swing JDialog监听回车键

在做项目时，发现在JDialog中，直接通过addKeyListener来监听回车键不起作用，无法监听到回车键，后面在网上查了些资料，终于解决了。方法如下：

KeyStroke stroke = KeyStroke.getKeyStroke(KeyEvent.VK_ENTER,0);

this.getRootPane().registerKeyboardAction(new ActionListener() {

@Override
    public void actionPerformed(ActionEvent e) {
     // TODO Auto-generated method stub
　//do something
  }
  }, stroke, JComponent.WHEN_IN_FOCUSED_WINDOW);

或者重写createRootPane方法，在方法里面注册keyboardaction

1. @Override
2. protected JRootPane createRootPane(){
3. KeyStroke  stroke = KeyStroke.getKeyStroke(KeyEvent.VK_ESCAPE,0);
4. JRootPane rootPane = new JRootPane();
5. rootPane.registerKeyboardAction(new ActionListener() {
6. @Override
7. public void actionPerformed(ActionEvent e) {
8. escapeKeyProc();
9. }
10. },stroke, JComponent.WHEN_IN_FOCUSED_WINDOW);
11. return rootPane;
12. }
