+The remaining help controller classes need to be named
explicitly by an application that wishes to make use of them.
There are currently the following help controller classes defined:
\begin{itemize}\itemsep=0pt
\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.
+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
+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
-details of use.
-\item \helpref{wxHtmlHelpController}{wxhtmlhelpcontroller}, a more sophisticated help controller using \helpref{wxHTML}{wxhtml}, in
+\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
recommended that you use the specific API for this class instead.
<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)\\

You may omit the file extension and a suitable one will be chosen. For
wxHtmlHelpController, the extensions zip, htb and hhp will be appended while searching for
-a suitable file. For WinHelp, the hlp extension is appended. For wxHelpControllerHtml (the
-standard HTML help controller), the filename is assumed to be a directory containing
-the HTML files.

\membersection{wxHelpController::DisplayBlock}\label{wxhelpcontrollerdisplayblock}
If the help viewer is not running, runs it and displays the
contents.

+\func{virtual bool}{DisplayContextPopup}{\param{int }{contextId}}

\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
+this call is equivalent to KeywordSearch. For MS HTML Help, wxHTML help and external HTML help,
+if {\it section} has a .htm
or .html extension, that HTML file will be displayed; otherwise
a keyword search is done.
If the help viewer is not running, runs it and displays the given section.

+{\it WinHelp, MS HTML Help} {\it sectionNo} is a context id.

+\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.

\membersection{wxHelpController::GetFrameParameters}\label{wxhelpcontrollergetframeparameters}
\func{virtual wxFrame *}{GetFrameParameters}{\param{const wxSize * }{size = NULL}, \param{const wxPoint * }{pos = NULL},
\param{bool *}{newFrameEachTime = NULL}}
-This reads the current settings for the help frame in the case of the
-wxHelpControllerHtml, setting the frame size, position and
-the newFrameEachTime parameters to the last values used. It also
-returns the pointer to the last opened help frame. This can be used
-for example, to automatically close the help frame on program
-shutdown.
-
-wxHtmlHelpController returns the frame,
-size and position.
+wxHtmlHelpController returns the frame, size and position.
For all other help controllers, this function does nothing
and just returns NULL.
\param{const wxSize \& }{size}, \param{const wxPoint \& }{pos = wxDefaultPosition},
\param{bool }{newFrameEachTime = FALSE}}
-For wxHelpControllerHtml, this allows the application to set the
-default frame title, size and position for the frame. If the title
-contains \%s, this will be replaced with the page title. If the
-parameter newFrameEachTime is set, the controller will open a new
-help frame each time it is called.
-
For wxHtmlHelpController, the title is set (again with \%s indicating the
page title) and also the size and position of the frame if the frame is already
open. {\it newFrameEachTime} is ignored.
