Re: ProgressMonitor takes too long to display in Sun's ProgressMonitorDemo

Skip,

I appreciate your advice. I tried adding a yield() call in the
ActualTask and also tried lowering the worker thread's priority to
Thread.MIN_PRIORITY. However, neither had any effect on how quickly
the ProgressMonitor displayed.

Are there any other suggestions on how to get the ProgessMonitor to
display more quickly?

For your information, the ActualTask's constructor is as follows:

ActualTask() {
//Fake a long task,
//making a random amount of progress every second.
//Thread.currentThread().yield();
while (!canceled && !done) {
try {
Thread.sleep(10000);
current += Math.random() * 100; //make some progress
if (current >= lengthOfTask) {
done = true;
current = lengthOfTask;
}
statMessage = "Completed " + current +
" out of " + lengthOfTask + ".";
} catch (InterruptedException e) {
System.out.println("ActualTask interrupted");
}
}
}
