Progress Monitor doesn't update

[ssaraceni]

Hi, I'm trying to use a ProgressMonitor in my Java application, to show information during a long process, but is only visible the title and the frame of the ProgressMonitor .

public static void updateProcess(){
            ... 
//code
            ....
                ProgressMonitor progressMon=new ProgressMonitor(null, "Operation in progress...", "", 0, 3600);
                progressMon.setProgress(0);
                ....
                progressMon.setProgress(1);
                progressMon.setNote("note1");
                ......

I call the updateProcess procedure when user clicks on a button, but the ProgressMonitor appear only some seconds after starting updateProcess and doesn't shown or update the progress bar.

What's wrong in the code? thanks

Most likely your updateProcess() method runs in the AWT EDT (Event Dispatch Thread).
Is that method started from some actionEvent() method or alike?

yes, the method is started from an actionlistener, that handles actions for some buttons on a panel of my GUI.

Ok, run your updateProcess() in a separate thread then so it won't stop that EDT
thread anymore.

I've created a new Thread into actionPerformed that calls the method, :

class ButtonHandler implements ActionListener{
		public void actionPerformed (ActionEvent e){
....
Thread op=new Thread(){                                         
public void run(){                                             Global.updateProcess();                                         
}                                     
};                                     
op.start();

but the problem still remain, now the progressMonitor isn't show. I've also set the setMillisToPopu p property to 0, but the progressMonitor isn't show.

In the updateProcess, after some instructions I've a Thread.sleep(30 00); but the method ends without the progressMonitor shown. What's the matter?

I don't know; in the API documentation for the ProgressMonitor there's a link to
the appropriate section of the tutorial. There's a ProgressMonitor Demo in there.
Check it out.

kind regards,
