JProgressBar的问题为
因为需要一个线程跟踪立即重绘进度条区域才可以
举了个小例子，刚写的，单击窗体就有0－100的动态显示
import t。BorderLayout;

import javax。 swing。JFrame;
import javax。swing。JPanel;
import javax。swing。JProgressBar;
public class Test2 extends JFrame {
private static final long serialVersionUID = 1L;
private JPanel jContentPane = ...全部
