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 desktop Windows, wxCHMHelpController is used (MS HTML Help).
+\item On Windows CE, wxWinceHelpController is used.
\item On all other platforms, wxHtmlHelpController is used if wxHTML is
-compiled into wxWindows; otherwise wxExtHelpController is used (for invoking an external
+compiled into wxWidgets; otherwise wxExtHelpController is used (for invoking an external
browser).
\end{itemize}
\item wxWinHelpController, for controlling Windows Help.
\item wxCHMHelpController, for controlling MS HTML Help. To use this, you need to set wxUSE\_MS\_HTML\_HELP
to 1 in setup.h and have htmlhelp.h header from Microsoft's HTML Help kit (you don't need
-VC++ specific htmlhelp.lib because wxWindows loads necessary DLL at runtime and so it
+VC++ specific htmlhelp.lib because wxWidgets loads necessary DLL at runtime and so it
works with all compilers).
\item wxBestHelpController, for controlling MS HTML Help or, if Microsoft's runtime is
not available, \helpref{wxHtmlHelpController}{wxhtmlhelpcontroller}. You need to provide
{\bf both} CHM and HTB versions of the help file. For 32bit Windows only.
\item wxExtHelpController, for controlling external browsers under Unix.
The default browser is Netscape Navigator. The 'help' sample shows its use.
+\item wxWinceHelpController, for controlling a simple {\tt .htm} help controller for Windows CE applications.
\item \helpref{wxHtmlHelpController}{wxhtmlhelpcontroller}, a sophisticated help controller using \helpref{wxHTML}{wxhtml}, in
a similar style to the Microsoft HTML Help viewer and using some of the same files.
Although it has an API compatible with other help controllers, it has more advanced features, so it is

Constructs a help instance object, but does not invoke the help viewer.
-\membersection{wxHelpController::\destruct{wxHelpController}}
+If you provide a window, it will be used by some help controller classes, such as
+wxCHMHelpController, wxWinHelpController and wxHtmlHelpController, as the
+parent for the help window instead of the value of \helpref{wxApp::GetTopWindow}{wxappgettopwindow}. You can also change the parent window later with
+\helpref{wxHelpController::SetParentWindow}{wxhelpcontrollersetparentwindow}.

Initializes the help instance with a help filename, and optionally a server socket
number if using wxHelp (now obsolete). Does not invoke the help viewer.
Displays the section as a popup window using a context id.
