- * @brief An object-oriented event demultiplexor and event handler
- * dispatcher that uses the Qt Library. This class declaration
- * also uses the extension facilities provided by the Qt. So,
- * readers of the class declaration should not be upset with
- * the appearence of the Keywords like Q_OBJECT, private slots
- * etc. They are specific to Qt which uses these as a call back
- * methods implementation mechanism.
