+ A help event is sent when the user has requested
+ context-sensitive help. This can either be caused by the
+ application requesting context-sensitive help mode via
+ wx.ContextHelp, or (on MS Windows) by the system generating a
+ WM_HELP message when the user pressed F1 or clicked on the query
+ button in a dialog caption.
+
+ A help event is sent to the window that the user clicked on, and
+ is propagated up the window hierarchy until the event is
+ processed or there are no more event handlers. The application
+ should call event.GetId to check the identity of the clicked-on
+ window, and then either show some suitable help or call
+ event.Skip if the identifier is unrecognised. Calling Skip is
+ important because it allows wxWindows to generate further events
+ for ancestors of the clicked-on window. Otherwise it would be
+ impossible to show help for container windows, since processing
+ would stop after the first window found.
