java setforeground_java 中的JProgressBar设置前景色foreground无效果
代码放不下呢。试试如何放下代码。90多行的代码，都贴不了。百度真小气。
先贴一半，追问，再贴public class ProgressBarDemo2 extends JPanel implements ActionListener,PropertyChangeListener{
private JProgressBar pb;
private JButton btn;
private JTextArea txt;
private Task task;
class Task extends SwingWorker {
public Void doInBackground() {
Random random = new Random();
int progress = 0;
setProgress(0);
try {
Thread.sleep(1000 + random.nextInt(2000));
} catch (InterruptedException ignore) {}
while (progress
try {
Thread.sleep(random.nextInt(1000));
} catch (InterruptedException ignore) {}
progress += random.nextInt(10);
setProgress(Math.min(progress, 100));
}
return null;
}
