swing 进度条-白红宇

1,进度条实例

2,创建一个进度条

       Java代码   
copyProgressBar = new JProgressBar();  
        copyProgressBar.setBorderPainted(true);  
        copyProgressBar.setString(PROGRESSINITSTR);  
        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   
/*** 
     * 测试进度条<br>百分比 
     */  
    public void testProgressBar() {  
        copyProgressBar.setIndeterminate(false);//取消"不确定模式"  
        copyProgressBar.setString(PROGRESSINITSTR);  
        copyProgressBar.setStringPainted(true);  
        new Thread(new Runnable() {  
            @Override  
            public void run() {  
                copyFileBtn.setEnabled(false);  
                int count = 0;  
                copyProgressBar.setForeground(progressDefaultColor);  
                try {  
                    Thread.sleep(50);  
                } catch (InterruptedException e) {  
                    e.printStackTrace();  
                }  
                while (true) {  
                    if(isStop()){  
                        setStop(false);  
                        break;  
                    }  
                    count++;  
                    try {  
                        Thread.sleep(50);  
                    } catch (InterruptedException e) {  
                        e.printStackTrace();  
                    }  
                    copyProgressBar.setString(count + "%");  
                    copyProgressBar.setValue(count);  
                    if (count >= 100) {  
                        copyProgressBar.setForeground(Color.GREEN);  
                        break;  
                    }  
                }  
                copyFileBtn.setEnabled(true);  
            }  
        }).start();  
    }  

模式二:不确定模式

启动进度条:

       Java代码   
/*** 
     * 左右移动<br> 
     * 将进度条设置为不确定模式 
     */  
    public void testIndeterminate() {  
        copyProgressBar.setStringPainted(false);  
        copyProgressBar.setIndeterminate(true);  
    }  

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   
public void stopIndeterminate(){  
        copyProgressBar.setIndeterminate(false);  
        copyProgressBar.setValue(100);  
    }
