\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 0 in setup.h, and link your application with Microsoft's htmlhelp.lib. Currently VC++ 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.
