+\func{virtual void}{AddPendingEvent}{\param{wxEvent\& }{event}}
+
+Adds an event to be processed later. The function will return immediately and the
+event will get processed in idle time using the \helpref{wxEvtHandler::ProcessEvent}{wxevthandlerprocessevent} 
+method.
+
+\wxheading{Parameters}
+
+\docparam{event}{Event to add to process queue.}
+
+\wxheading{Remarks}
+
+Note that this requires that the event implements 
+\helpref{CopyObject}{wxobjectcopyobject} 
+method so that the event can be duplicated and stored until it gets processed later.
+Not all events in wxWindows currently fully implement this method,
+so you may have to look at the source to verify this.
+
+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}.)
+
+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.
+
+% VZ: bad idea IMHO - we're going to have a lot of problems with this
+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.
