+Most help controller classes actually derive from wxHelpControllerBase and have

+appropriate class is aliased to the name wxHelpController for each platform, as follows:
+
+\begin{itemize}\itemsep=0pt
+\item On Windows, wxWinHelpController is used.
+\item On all other platforms, wxHelpControllerHtml is used if wxHTML is
+compiled into wxWindows; otherwise wxExtHelpController is used (for invoking an external
+browser).
+\end{itemize}
+
+The remaining help controller classess need to be named
+explicitly by an application that wishes to make use of them.
