The ICircularSliderNotifyHandler class processes events for all classes of circular sliders.
This class handles events that require the circular slider class 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.
Use these functions to construct and destruct objects of the ICircularSliderNotifyHandler class.
