2.9 窗口监听事件

    public static void main(String[] args) {
        new MyWindow();
    }
}
class MyWindow extends Frame {
    public MyWindow() {
        setVisible(true);
        setBounds(200, 200, 600, 600);
        setBackground(Color.blue);

        addWindowListener(new WindowAdapter() {
            //玩下激活状态
            @Override
            public void windowActivated(WindowEvent e) {
                super.windowActivated(e);
                MyWindow source = (MyWindow) e.getSource();
                source.setTitle("激活状态");
            }
            //关闭

            @Override
            public void windowClosing(WindowEvent e) {
                System.exit(0);
            }
        });




        //窗口监听的所有方法
        /*
        windowOpened      打开
        windowActivated   激活（获得焦点状态）
        windowDeactivated 非激活（失去焦点状态）
        windowIconified   最小化
        windowDeiconified 最小化恢复正常
        windowClosing     关闭（右上角X），优先于windowClosed
        windowClosed      关闭，DISPOSE_ON_CLOSE时才会被调用
