Hi
I have a problem in my current application(Works as application and applet also).
 
What it does basically is it sends a command to VB through Perl script and waits for the resultimage. As soon as it finds the image in the path it fetches that and shows that on screen.

Main thread waits and second thread waits and gets the image and as soon as it gets the image it notifies the main thread.
But now I want to show a ProgressBar while it is waitng for the image, but the problem is as the Main thread is waiting, the progressBar(Or even any animated gif) is not working. It is just showing the empty window.

Do you have any ideas...solutions????

Thanks in Advance

I have extended JDialog and added the progress bar to a panel. This is a method I use to display the meter.
This works for JBuilder 4. What are you useing to build your java program?


JProgressBar METER_bar = new JProgressBar(0, 100);

Use a method to display status bar and percentage complete

    public void Display(int total, int amount)
    {
        // Make the frame visible
        this.setVisible(true);

        // If incorrect value is passed in, return
        if ((total == 0) || (amount > total))
            return;

        // Set METER_total equal to total passed in
        if (total != METER_total)
            METER_total = total;

        // Set METER_amount to amount arg passed in
        METER_amount = amount;

        // Call Draw() to update progress bar
        Draw();

        METER_bar.repaint();
    }
