progress monitor dialogue box timing

Hi I was going reading the code on the following site:
http://www.jguru.com/faq/view.jsp?EID=534271

In the comment it mentions that by default, the dialog won't appear
unless the overall estimate is over 2 seconds.

Is there a way to change the code so that the progress monitor
dialogue box appears as soon as the file gets read?

Thanks,
Undbund

"If it calculates that the task will take more than 2000 milliseconds to
complete, the progress dialog appears. To adjust the minimum waiting
period, invoke setMillisToDecidedToPopup. To adjust the minimum progress
time required for a dialog to appear, invoke setMillisToPopup."

But note that the decision will only be made from within
ProgressMonitor.setProgress, so the dialog will only if at least
something has been written. To make it always appear initially, call
setProgress(0) explicitly once initially.

I remember setting up a custom Timer for this to decide even if no progress
is being made.
