The IListBoxNotifyHandler class processes events for all classes of list boxes.
This class is designed to handle events that require the list box classes to generate a notification. If notifications are enabled for this class, a notification is generated and sent to all observers when the proper conditions for the specific notification exist.
You can construct and destruct objects of this class.
