swing 进度条

1,进度条实例

 

2,创建一个进度条

Java代码  

1. copyProgressBar = new JProgressBar();  
2.         copyProgressBar.setBorderPainted(true);  
3.         copyProgressBar.setString(PROGRESSINITSTR);  
4.         copyProgressBar.setStringPainted(true);  

3,进度条两种模式

模式一:百分比模式(determinate mode)

更新进度条:

Java代码  

1. /*** 
2.      * 测试进度条<br>百分比 
3.      */  
4.     public void testProgressBar() {  
5.         copyProgressBar.setIndeterminate(false);//取消"不确定模式"  
6.         copyProgressBar.setString(PROGRESSINITSTR);  
7.         copyProgressBar.setStringPainted(true);  
8.         new Thread(new Runnable() {  
9.             @Override  
10.             public void run() {  
11.                 copyFileBtn.setEnabled(false);  
12.                 int count = 0;  
13.                 copyProgressBar.setForeground(progressDefaultColor);  
14.                 try {  
15.                     Thread.sleep(50);  
16.                 } catch (InterruptedException e) {  
17.                     e.printStackTrace();  
18.                 }  
19.                 while (true) {  
20.                     if(isStop()){  
21.                         setStop(false);  
22.                         break;  
23.                     }  
24.                     count++;  
25.                     try {  
26.                         Thread.sleep(50);  
27.                     } catch (InterruptedException e) {  
28.                         e.printStackTrace();  
29.                     }  
30.                     copyProgressBar.setString(count + "%");  
31.                     copyProgressBar.setValue(count);  
32.                     if (count >= 100) {  
33.                         copyProgressBar.setForeground(Color.GREEN);  
34.                         break;  
35.                     }  
36.                 }  
37.                 copyFileBtn.setEnabled(true);  
38.             }  
39.         }).start();  
40.     }  

模式二:不确定模式

 启动进度条:

Java代码  

1. /*** 
2.      * 左右移动<br> 
3.      * 将进度条设置为不确定模式 
4.      */  
5.     public void testIndeterminate() {  
6.         copyProgressBar.setStringPainted(false);  
7.         copyProgressBar.setIndeterminate(true);  
8.     }  

4,说明

(1)copyProgressBar.setString(PROGRESSINITSTR);

copyProgressBar.setStringPainted(true);

作用:在进度条上显示百分比的文字

(2)停止不确定模式:

Java代码  

1. public void stopIndeterminate(){  
2.         copyProgressBar.setIndeterminate(false);  
3.         copyProgressBar.setValue(100);  
4.     }
