 This class is used for idle events, which are generated when the system is idle.
 
+By default, idle events are sent to all windows. If this is causing a significant
+overhead in your application, you can call \helpref{wxIdleEvent::SetMode}{wxidleeventsetmode} with
+the value wxIDLE\_PROCESS\_SPECIFIED, and set the wxWS\_EX\_PROCESS\_IDLE extra
+window style for every window which should receive idle events.
+
+The function \helpref{wxWindow::OnInternalIdle}{wxwindowoninternalidle} is
+also provided for internal purposes, and cannot be disabled. wxUpdateUIEvents
+are sent from OnInternalIdle.

+This function looks at the mode used (see \helpref{wxIdleEvent::SetMode}{wxidleeventsetmode}),

+to only send idle events to windows with the wxWS\_EX\_PROCESS\_IDLE extra window style set.
