public class GTaskMonitor extends java.lang.Object implements TaskMonitor, CancelledListener
Implementation of a TaskMontor that can be "attached" to a GProgressBar. The GTaskMonitor is a non-gui object for tracking the progress of a GTaskGroup or GTask. It is created by the GTaskManager as tasks are scheduled. GUIs that wish to display the progress of the groups and tasks can set a GProgressBar into a GTaskMonitor and it will display the progress.
