怎么在进度条更新的时候刷新页面？

    private void loading(Component component)
    {
        for(int i=1;i<=100;++i)
        {
            try {
                pgb.setProgressValue(i);
                pgb.setProgressHintText(String.format("%d%%", i));
                sleep(10);
            }
            catch (InterruptedException e) {
                e.printStackTrace();
            }
        }
        MyToast.showDialog(this,"Completed");
    }
