+\section2 Using enumeration values as signal parameters
+
+C++ signals may pass enumeration values as signal parameters to QML, providing that the enumeration
+and the signal are declared within the same class, or that the enumeration value is one of those declared
+in the \l {Qt}{Qt Namespace}.
+
+Additionally, if a C++ signal with an enum parameter should be connectable to a QML function using the
+\l {Connecting signals to methods and other signals}{connect()} function, the enum type must be
+registered using qRegisterMetaType().
+
+For QML signals, enum values may be used as signal parameters using the \c int type:

 As a convenience, some basic types can be specified in QML using format strings to make it easier to
