Progress Bar

[Danish Shaukat]

Hi !
I want to make a progress bar using a non-interactive gauge. I want that after a specified time period the bar shows progress. But i can't figure out how do i make this thing. I have tried to make the current thread sleep for some time and then display the gauge, but it always ends up displaying the last screen.
Regards

Hi Danish,
You're in luck... I'm on the Gauge section of my J2ME book, and the example I'm working on has that exact piece of code you're looking for.
You need to create a Timer object, as well as a TimerTask object that will be executed when you schedule its execution:

tm = new Timer();
tt = new DownloadTimer();
tm.scheduleAtFixedRate(tt, 0, 1000);
private class DownloadTimer extends TimerTask{
        
        public final void run(){
            
            // Is current value of gauge less than max?
            if (gaProgress.getValue() < gaProgress.getMaxValue()){
                gaProgress.setValue(gaProgress.getValue() + 1);
            } 
            else {
                // Remove the stop command and replace w/ exit - download complete
                fmMain.removeCommand(cmStop);
                fmMain.addCommand(cmExit);
                gaProgress.setLabel("Download Complete!");
                
                // Stop timer
                cancel();
            }
        }
    }

Hope that helps...
