第九天

今天我添加了选项卡窗口。话不多说，上代码：

        jp.add("用户", p5); // 添加子容器 并且为选项卡添加名字
        f.add(jp, BorderLayout.CENTER); // 将选项卡窗体添加到 主窗体上去
    }

    mainApp() {// init frame

        f.setLayout(new BorderLayout());

    }

        JMenuBar menubar = new JMenuBar();
        JMenu[] menus = new JMenu[] { new JMenu("文件"), new JMenu("选项"), new JMenu("查看") };
        for (int i = 0; i < menus.length; i++) {
            menubar.add(menus[i]);
        }
        f.setJMenuBar(menubar);
    }
    
    
    void initProcess() {

        p1.add(pa.panel);
        pa.initTable();
        //pa.setTable();

        Boolean result = false;
        int count = 0;
        while (!result) {
            try {
                Thread.sleep(10000); // 设置暂停的时间 5 秒
                if (pa.isUpdate == true) {
                    count++;
                    pa.setTable();
                    System.out.println(sdf.format(new Date()) + "--循环执行第" + count + "次");
