Progress Bar refreshing!

[Jenith shiva]

Hi,
I have a JProgressBar on my status pane.
As I progress I need to set the value on the Progress Bar so I call this method...
public void setValue(int value){
SwingUtilities.invokeLater(new Runnable(){
public void run(){
m_progressBar.setValue(value);
m_progressBar.updateUI();
}
});
}
This should repaint the ProgressBar with the value as the rest of the task is in progress, but it does not refresh itself until the whole task is complete.

Please help me out in doing the needfull to refresh the ProgressBar as and when the setValue() method is called.

Thanks n Regards
Jenith

You should have posted this message in the Swing/awt forum. Bartender, can you do that?
The updateUI method code is useless here. It is used to change properties of the look-and-feel, which is here not the case. So you can remove it.
Swing uses a modified Model-View-Controller (MVC pattern), which a Model-UI pattern. When a call to setValue() in JProgressBar is made, this call is delegated to the model which is embedded in the JProgressBar. The model then notifies the view that it should repaint. This should be automatic. So I don't quite get the point using invokeLater.
Check

package test;
import javax.swing.*;
import javax.swing.event.*;
import java.awt.event.*;
import java.awt.*;
public class ProgressBar implements ActionListener {
        JProgressBar pb=new JProgressBar(0,5) ;
JButton b=new JButton("push");
int i=0;

public ProgressBar() {

        JFrame frame = new JFrame( "PBTest" );
b.addActionListener(this);
       frame.getContentPane().add( pb, BorderLayout.CENTER );
        frame.getContentPane().add( b, BorderLayout.NORTH );
        frame.pack();
        frame.setVisible( true );
}
    public static void main( String args[] ) { 
ProgressBar lt=new ProgressBar();
     
    }  // main
public void actionPerformed(ActionEvent e) {
i++;
pb.setValue(i);
}
