+
+  The class encapsulates a pointer to an object of type {\tt MDDObj}.
+  Its purpose is to have the {\tt MDDObj} object available as a descendant
+  of class {\tt QtData}. The class does not care of the memory management
+  of the {\tt MDDObj} object.
+
+  Note: The attribute lifetime of the superclass QtData ist set implicit
+  in the constructor functions!
