Is it possible to define a range for JProgressBar ??

Question

I want to set a range on JProgressBar. Let's say I want to set red color for "30%" of progress bar to "70%" of progress bar.
If i do:
JProgressBar progressBar= new JProgressBar(JProgressBar.HORIZONTAL);
          progressBar.setBackground(Color.yellow);
          progressBar.setForeground(Color.red);
          progressBar.setMinimum(0);
          progressBar.setMaximum(100);
          progressBar.setValue(30);
// it will paint till 30% of the bar.
progressBar.setValue(70);
// it will paint from beginning of bar to 70% of the bar.
Is it possible to paint from value 30 to value 70. (is it possible to do it my defining our own class which extends from JProgressBar ??? I tried but was not successful)
any help would be appreciated.
regards,
Kumar

Hi,
try this ;-)
JProgressBar progress;
public synchronized void addProgress (int newValue) {
   for (int i=progress.getValue(); i<=newValue; i++)  {
      progress.setValue(i);
      try  { Thread.sleep(20);  }
       catch (InterruptedException e)  { }
    progress.setString (newValue + " %");
}
