+* that are not derived from QObject. It can be used as a member
+* variable of those classes.
+*
+* There are some classes it is not possible to derive from QObject and
+* have the signals work. Certain multiple inheritance classes which cannot
+* have QObject as the first derived class, cannot use Qt signals.
