+DocStr(wxHelpEvent,
+"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.",
