java Swing 进度条 时间进度条

项目中用到了java swing 的时间进度滚动条，所以写了一个 测试类，供大家参考，下面是 具体的实现类

package com.original.client.widget.execcenter;

import java.awt.BorderLayout;

import java.awt.Color;

import java.awt.Container;

import java.awt.Dimension;

import java.awt.event.ActionEvent;

import java.awt.event.ActionListener;

import javax.swing.JButton;

import javax.swing.JFrame;

import javax.swing.JLabel;

import javax.swing.JPanel;

import javax.swing.JProgressBar;

import javax.swing.Timer;

import javax.swing.event.ChangeEvent;

import javax.swing.event.ChangeListener;

import net.miginfocom.swing.MigLayout;
