-Note that this requires that the event has a fully implemented Clone()
-method so that the event can be duplicated and stored until it gets processed later.
-Not all events in wxWindows currently have a fully implemented Clone() method,
-so you may have to look at the source to verify this.
+The difference between sending an event (using the
+\helpref{ProcessEvent}{wxevthandlerprocessevent} method) and posting it is
+that in the first case the event is processed before the function returns,
+while in the second case, the function returns immediately and the event will
+be processed sometime later (usually during the next event loop iteration).
 
-This methods automatically wakes up idle handling even if the underlying window 
-system is currently idle anyway and thus would not send any idle events. (Waking
-up the idle handling is done calling \helpref{::wxWakeUpIdle}{wxwakeupidle}.)
+A copy of {\it event} is made by the function, so the original can be deleted
+as soon as function returns (it is common that the original is created on the
+stack).  This requires that the \helpref{wxEvent::Clone}{wxeventclone} method
+be implemented by {\it event} so that it can be duplicated and stored until
+it gets processed.
 
-This is also the method to call for inter-thread communication. In
-a multi-threaded program, you will often have to inform the main GUI thread
-about the status of other working threads and this has to be done using this
-method - which also means that this method is thread safe by means of using
-crtical sections where needed.

-Furthermore, it may be noted that some ports of wxWindows will probably move
-to using this method more and more in preference over calling ProcessEvent()
-directly so as to avoid problems with reentrant code.
