将ActionListener与JButton一起使用

class MenuAction extends Action {
    public void actionPerformed() { /* close menu */ }
}

public void MyMenu() { // or where your menu construction code occurs
    ...
    JButton mybutton1 =
        new JButton(new MenuAction() {
                public void performAction() {
                    // close the menu first
                    super.actionPerformed();
                    // then perform the button\'s action
                    /* button1\'s behaviour */
                }
            });
    ...

ActionListener closeMenu = ...;
Action myaction1 = ...;
JButton mybutton1 = new JButton();
mybutton1.addActionListener(closeMenu);
mybutton1.setAction(myaction1);
