\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 neccessary 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 wxHelpControllerHtml, using \helpref{wxHTML}{wxhtml} to display help. See {\tt wx/helpwxht.h} for
<wx/help.h> (wxWindows chooses the appropriate help controller class)\\
<wx/helpbase.h> (wxHelpControllerBase class)\\
<wx/helpwin.h> (Windows Help controller)\\
+<wx/msw/helpchm.h> (MS HTML Help controller)\\
<wx/generic/helpext.h> (external HTML browser controller)\\
<wx/generic/helpwxht.h> (simple wxHTML-based help controller)\\
<wx/html/helpctrl.h> (advanced wxHTML based help controller: wxHtmlHelpController)
{\it WinHelp:} Refers to the context number.
+{\it MS HTML Help:} Refers to the context number.
+
{\it External HTML help:} the same as for \helpref{wxHelpController::DisplaySection}{wxhelpcontrollerdisplaysection}.
{\it wxHtmlHelpController:} {\it sectionNo} is an identifier as specified in the {\tt .hhc} file. See \helpref{Help files format}{helpformat}.
+This function is for backward compatibility only, and applications should use \helpref{wxHelpController}{wxhelpcontrollerdisplaysection} instead.
+
\membersection{wxHelpController::DisplayContents}\label{wxhelpcontrollerdisplaycontents}
\func{virtual bool}{DisplayContents}{\void}
If the help viewer is not running, runs it and displays the
contents.
+\membersection{wxHelpController::DisplayContextPopup}\label{wxhelpcontrollerdisplaycontextpopup}
+
+\func{virtual bool}{DisplayContextPopup}{\param{int }{contextId}}
+
+Displays the section as a popup window using a context id.
+
+Returns FALSE if unsuccessful or not implemented.
+
\membersection{wxHelpController::DisplaySection}\label{wxhelpcontrollerdisplaysection}
+\func{virtual bool}{DisplaySection}{\param{const wxString\&}{ section}}
+
+If the help viewer is not running, runs it and displays the given section.
+
+The interpretation of {\it section} differs between help viewers. For most viewers,
+this call is equivalent to KeywordSearch. For MS HTML Help, external HTML help
+and simple wxHTML help, if {\it section} has a .htm
+or .html extension, that HTML file will be displayed; otherwise
+a keyword search is done.
+
\func{virtual bool}{DisplaySection}{\param{int}{ sectionNo}}
If the help viewer is not running, runs it and displays the given section.
-{\it WinHelp:} {\it sectionNo} is a context id.
+{\it WinHelp, MS HTML Help:} {\it sectionNo} is a context id.
-{\it External HTML help/wxHTML based help:} wxExtHelpController and wxHelpControllerHtml implement {\it sectionNo} as an id in a map file, which is of the form:
+{\it External HTML help/simple wxHTML help:} wxExtHelpController and wxHelpControllerHtml implement {\it sectionNo} as an id in a map file, which is of the form:
\begin{verbatim}
0 wx.html ; Index
{\it wxHtmlHelpController:} {\it sectionNo} is an identifier as specified in the {\tt .hhc} file. See \helpref{Help files format}{helpformat}.
+See also the help sample for notes on how to specify section numbers for various help file formats.
+
+\membersection{wxHelpController::DisplayTextPopup}\label{wxhelpcontrollerdisplaytextpopup}
+
+\func{virtual bool}{DisplayTextPopup}{\param{const wxString\&}{ text}, \param{const wxPoint\& }{pos}}
+
+Displays the text in a popup window, if possible.
+
+Returns FALSE if unsuccessful or not implemented.
+
\membersection{wxHelpController::GetFrameParameters}\label{wxhelpcontrollergetframeparameters}
\func{virtual wxFrame *}{GetFrameParameters}{\param{const wxSize * }{size = NULL}, \param{const wxPoint * }{pos = NULL},
If the help viewer is not running, runs it, and searches for sections matching the given keyword. If one
match is found, the file is displayed at this section.
-{\it WinHelp:} If more than one match is found,
+{\it WinHelp, MS HTML Help:} If more than one match is found,
the first topic is displayed.
-{\it External HTML help:} If more than one match is found,
+{\it External HTML help, simple wxHTML help:} If more than one match is found,
a choice of topics is displayed.
{\it wxHtmlHelpController:} see \helpref{wxHtmlHelpController::KeywordSearch}{wxhtmlhelpcontrollerkeywordsearch}.
