java Swing 进度条 多线程问题 附代码

[ilovesnow]

目标：
当我点击主界面上的开始按钮，然后就会用大约1分钟来进行数据处理。但是在数据处理的时候，整个软件就像死了一样（其实没有),刷新还在继续，所以我想达到这样的效果：点击开始按钮，就弹出一个进度条在不停的动，表示程序正在运行，并没有死，然后进度条在持续更新，从1% 到 100%，当数据处理结束时，进度条消失，显示主界面,怎么实现呀！
望大家处处注意！谢谢！
问题：程序无法实现 【处理中】对话框进度条与 数据处理同步开始的功能。如何使他们同步进行？
即：数据处理 一开始，就让进度条对话框弹出，且 从0% 开始 向 100% 依次滚动？
附代码。（数据处理用 hread.sleep(new Random().nextInt(60000));来模拟）

up一下。

新问题：
有没有办法在主对话框（TestMainDlg.java ）里，控制 子对话框的ActionPerform 事件？
