IlvThreadedActivityMonitor is a class that
monitors the progress of several tasks running in separate threads.
These tasks first register with this monitor through the registerThreadedActivity method, and then
notify the monitor of any progress they make by calling the updateActivityProgress method. Eventually, a
task can be removed from the list by calling unregisterThreadedActivity method. A task
that reports a progress reading of one hundred percent is
automatically unregistered from the monitor.
In its turn, the monitor notifies any registered listeners of the
progress being made by the monitored tasks. Multithread Monitor shows the IlvThreadedActivityMonitorPanel class, which
is a Swing component implementing the IlvThreadedActivityMonitor.ActivityListener
interface. It displays progress bars for monitored activities.

If you want to display the progress of your own threaded tasks on
this IlvThreadedActivityMonitorPanel, here are the
basic actions you should take:
IlvManagerView view; // the main view of the application
// Get the manager of this view (provided that it was set somewhere before)
IlvManager manager = view.getManager();
// Get the activity monitor associated with this manager
IlvThreadedActivityMonitor monitor =
IlvThreadedActivityMonitorProperty.GetThreadedActivityMonitor(manager);
if (monitor != null) {
// Notify the monitor of the progress of this activity
monitor.updateActivityProgress(this,100,null);
};
