NLSOUND::CListenerUser Class Reference

#include <listener_user.h>

Inheritance diagram for NLSOUND::CListenerUser:

NLSOUND::UListener

Detailed Description

Implementation of UListener

This implementation does not check if the properties have changed or not. Therefore it is suggested to test them and not to call the set methods if there is no change.
