window hierarchy until the event is processed or there are no more event handlers.
The application should call wxEvent::GetId to check the identity of the clicked-on window,
and then either show some suitable help or call wxEvent::Skip if the identifier is unrecognised.
-Calling Skip is important because it allows wxWindows to generate further events for ancestors
+Calling Skip is important because it allows wxWidgets 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.

Constructor.

+
+\constfunc{wxHelpEvent::Origin }{GetOrigin}{\void}
+
+Returns the origin of the help event which is one of the following values:
+
+\twocolwidtha{7cm}
+\begin{twocollist}\itemsep=0pt
+\twocolitem{{\bf Origin\_Unknown}}{Unrecognized event source.}
+\twocolitem{{\bf Origin\_Keyboard}}{Event generated by \texttt{F1} key press.}
+\twocolitem{{\bf Origin\_HelpButton}}{Event generated by
+\helpref{wxContextHelp}{wxcontexthelp} or using the "?" title bur button under
+MS Windows.}
+\end{twocollist}
+
+The application may handle events generated using the keyboard or mouse
+differently, e.g. by using \helpref{wxGetMousePosition()}{wxgetmouseposition}
+for the mouse events.

\membersection{wxHelpEvent::GetPosition}\label{wxhelpeventgetposition}
\constfunc{const wxPoint\&}{GetPosition}{\void}
Returns the left-click position of the mouse, in screen coordinates. This allows
the application to position the help appropriately.
+\membersection{wxHelpEvent::SetOrigin}\label{wxhelpeventsetorigin}
+
+\func{void}{SetOrigin}{\param{wxHelpEvent::Origin }{origin}}
+
+Set the help event origin, only used internally by wxWidgets normally.
