+Returns a copy of the event.
+
+Any event that is posted to the wxWindows event system for later action (via
+\helpref{wxEvtHandler::AddPendingEvent}{wxevthandleraddpendingevent} or
+\helpref{wxPostEvent}{wxpostevent}) must implement this method. All wxWindows
+events fully implement this method, but any derived events implemented by the
+user should also implement this method just in case they (or some event
+derived from them) are ever posted.
+
+All wxWindows events implement a copy constructor, so the easiest way of
+implementing the Clone function is to implement a copy constructor for
+a new event (call it MyEvent) and then define the Clone function like this:
+\begin{verbatim}
+    wxEvent *Clone(void) const { return new MyEvent(*this); }
+\end{verbatim}
