ProgressMonitor in thred, call from other class

Question

Hi all
I have a problem using the ProgressMonitor... I just want to update the progress from another class.
So what i was thinking was:
I could implement a method that invoked the thread, and thereby updating the progress.
The problem occurs when the calculating steps is going. The parent class calls ProgressDiff fine but it doesn't update it, it doesn't even show anything. Just when the task is finished it says, simulation done!!
I have tried searching alot on these forums, and on google, but all methods implementing progressmonitor uses a call from within the class. <- Not what I want. :=)
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import java.beans.*;
public class ProgressDiff extends JFrame {
    public ProgressMonitor progressMonitor;
     public int tll;
    public ProgressDiff(int maks, String set) {
          super("Progress");
          setSize(250, 100);
        progressMonitor = new ProgressMonitor(null,
                                  "Differentiere og l�ser\n" + set,
                                  "", 0, maks);
        progressMonitor.setProgress(0);
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
          setProgressTal(0, false);
          setLocationRelativeTo(null);
          setVisible(true);
    public void setProgressTal(int fremGang, boolean done) {
          tll = fremGang;
          SwingUtilities.invokeLater(new Update());
          if (done) {
               Toolkit.getDefaultToolkit().beep();
               JOptionPane.showMessageDialog(null,
                    "Simuleringen er f�rdig."
                    , "F�rdig",
                    JOptionPane.INFORMATION_MESSAGE);
     class Update implements Runnable {
        public void run() {
               if (progressMonitor.isCanceled()) {
               Toolkit.getDefaultToolkit().beep();
               JOptionPane.showMessageDialog(null,
                    "Simuleringen er f�rdig."
                    , "F�rdig",
                    JOptionPane.INFORMATION_MESSAGE);
               } else {
                    progressMonitor.setProgress(tll);
                    progressMonitor.setNote(String.format("Completed %d%%.\n", tll));
}Any help would be apreciable!!
Thx.

Thx for the reply, I now have a working Progressmonitor which i easily can control

}Sry about the comment, and the danish... But this works really nice, if you place the swingworker around the method needing progressmonitor.
