+This help controller provides an easy way of displaying HTML help in your
+application (see {\it test} sample). The help system is based on {\bf books}
+(see \helpref{AddBook}{wxhtmlhelpcontrolleraddbook}). A book is a logical
+section of documentation (for example "User's Guide" or "Programmer's Guide" or
+"C++ Reference" or "wxWidgets Reference"). The help controller can handle as
many books as you want.
+Although this class has an API compatible with other wxWidgets
+help controllers as documented by \helpref{wxHelpController}{wxhelpcontroller}, it
+is recommended that you use the enhanced capabilities of wxHtmlHelpController's API.
+
wxHTML uses Microsoft's HTML Help Workshop project files (.hhp, .hhk, .hhc) as its
native format. The file format is described \helpref{here}{helpformat}.
Have a look at docs/html/ directory where sample project files are stored.
-You can use tex2rtf to generate MHHW projects (see wxHTML homepage for details).
+You can use Tex2RTF to produce these files when generating HTML, if you set {\bf htmlWorkshopFiles} to {\bf true} in
+your tex2rtf.ini file. The commercial tool HelpBlocks (www.helpblocks.com) can also create these files.
+
+\wxheading{Note}
-In order to use the controller in your application under Windows you must
-have following line in your .rc file:
+It is strongly recommended to use preprocessed {\bf .hhp.cached} version of
+projects. It can be either created on-the-fly (see
+\helpref{SetTempDir}{wxhtmlhelpcontrollersettempdir}) or you can use
+{\bf hhp2cached} utility from {\it utils/hhp2cached} to create it and
+distribute the cached version together with helpfiles. See {\it samples/html/help}
+sample for demonstration of its use.

Constructor.
+\wxheading{Parameters}
+
+{\it style} is a combination of these flags:
+
+\begin{twocollist}\itemsep=0pt
+\twocolitem{\windowstyle{wxHF\_TOOLBAR}}{The help window has a toolbar.}
+\twocolitem{\windowstyle{wxHF\_FLAT\_TOOLBAR}}{The help window has a toolbar with flat buttons (aka coolbar).}

-\membersection{wxHtmlHelpController::SetTitleFormat}\label{wxhtmlhelpcontrollersettitleformat}
+\membersection{wxHtmlHelpController::AddBook}\label{wxhtmlhelpcontrolleraddbook}
-\func{void}{SetTitleFormat}{\param{const wxString\& }{format}}
+\func{bool}{AddBook}{\param{const wxFileName\& }{bookFile}, \param{bool }{showWaitMsg}}
-Sets format of title of the frame. Must contain exactly one "\%s"
-(for title of displayed HTML page).
+\func{bool}{AddBook}{\param{const wxString\& }{bookUrl}, \param{bool }{showWaitMsg}}
+Adds book (\helpref{.hhp file}{helpformat} - HTML Help Workshop project file) into the list of loaded books.
+This must be called at least once before displaying any help.
-\membersection{wxHtmlHelpController::SetTempDir}\label{wxhtmlhelpcontrollersettempdir}
+{\it bookFile} or {\it bookUrl} may be either .hhp file or ZIP archive
+that contains arbitrary number of .hhp files in
+top-level directory. This ZIP archive must have .zip or .htb extension
+(the latter stands for "HTML book"). In other words, {\tt AddBook(wxFileName("help.zip"))}
+is possible and is the recommended way.
-\func{void}{SetTempDir}{\param{const wxString\& }{path}}
+\wxheading{Parameters}
-Sets path for storing temporary files (cached binary versions of index and contents files. These binary
-forms are much faster to read.) Default value is empty string (empty string means
-that no cached data are stored). Note that these files are NOT
-deleted when program exits!
+\docparam{showWaitMsg}{If true then a decoration-less window with progress message is displayed.}
+\docparam{bookFile}{Help book filename. It is recommended to use this prototype
+instead of the one taking URL, because it is less error-prone.}
+\docparam{bookUrl}{Help book URL (note that syntax of filename and URL is
+different on most platforms)}
+\wxheading{Note}
-\membersection{wxHtmlHelpController::AddBook}\label{wxhtmlhelpcontrolleraddbook}
+Don't forget to install the archive wxFileSystem handler with
+{\tt wxFileSystem::AddHandler(new wxArchiveFSHandler);} before calling this method
+on a .zip or .htb file!
-\func{bool}{AddBook}{\param{const wxString\& }{book}, \param{bool }{show_wait_msg}}
+\membersection{wxHtmlHelpController::CreateHelpDialog}\label{wxhtmlhelpcontrollercreatehelpdialog}
-Adds book (\helpref{.hhp file}{helpformat} - HTML Help Workshop project file) into the list of loaded books.
-This must be called at least once before displaying any help.
+\func{virtual wxHtmlHelpDialog*}{CreateHelpDialog}{\param{wxHtmlHelpData * }{data}}
+
+This protected virtual method may be overridden so that when specifying the wxHF\_DIALOG style, the controller
+uses a different dialog.
-If {\it show_wait_msg} is TRUE then a decorationless window with progress message is displayed.
+\membersection{wxHtmlHelpController::CreateHelpFrame}\label{wxhtmlhelpcontrollercreatehelpframe}
+\func{virtual wxHtmlHelpFrame*}{CreateHelpFrame}{\param{wxHtmlHelpData * }{data}}
+
+This protected virtual method may be overridden so that the controller
+uses a different frame.
\membersection{wxHtmlHelpController::Display}\label{wxhtmlhelpcontrollerdisplay}
You can specify the page in many ways:
-\begin{itemize}
+\begin{itemize}\itemsep=0pt
\item as direct filename of HTML document
\item as chapter name (from contents) or as a book name
\item as some word from index
-\item even as any word (will be searched)
+\item even as any word (will be searched)
\end{itemize}
Looking for the page runs in these steps:
-\begin{enumerate}
+\begin{enumerate}\itemsep=0pt
\item try to locate file named x (if x is for example "doc/howto.htm")
\item try to open starting page of book named x
\item try to find x in contents (if x is for example "How To ...")
This alternative form is used to search help contents by numeric IDs.
-
-
+\pythonnote{The second form of this method is named DisplayId in
+wxPython.}
\membersection{wxHtmlHelpController::DisplayContents}\label{wxhtmlhelpcontrollerdisplaycontents}
Displays help window and focuses index panel.
-
\membersection{wxHtmlHelpController::KeywordSearch}\label{wxhtmlhelpcontrollerkeywordsearch}
-\func{bool}{KeywordSearch}{\param{const wxString\& }{keyword}}
+\func{bool}{KeywordSearch}{\param{const wxString\& }{keyword}, \param{wxHelpSearchMode }{mode = wxHELP\_SEARCH\_ALL}}
+
+Displays help window, focuses search panel and starts searching. Returns true
+if the keyword was found. Optionally it searches through the index (mode =
+wxHELP\_SEARCH\_INDEX), default the content (mode = wxHELP\_SEARCH\_ALL).
+
+{\bf Important:} KeywordSearch searches only pages listed in .hhc file(s).
+You should list all pages in the contents file.
+
+\membersection{wxHtmlHelpController::ReadCustomization}\label{wxhtmlhelpcontrollerreadcustomization}
+
+\func{void}{ReadCustomization}{\param{wxConfigBase* }{cfg}, \param{wxString }{path = wxEmptyString}}
+
+Reads the controller's setting (position of window, etc.)
+
+\membersection{wxHtmlHelpController::SetTempDir}\label{wxhtmlhelpcontrollersettempdir}
+
+\func{void}{SetTempDir}{\param{const wxString\& }{path}}
+
+Sets the path for storing temporary files - cached binary versions of index and contents files. These binary
+forms are much faster to read. Default value is empty string (empty string means
+that no cached data are stored). Note that these files are {\it not}
+deleted when program exits.
+
+Once created these cached files will be used in all subsequent executions
+of your application. If cached files become older than corresponding .hhp
+file (e.g. if you regenerate documentation) it will be refreshed.
-Displays help window, focuses search panel and starts searching.
-Returns TRUE if the keyword was found.
+\membersection{wxHtmlHelpController::SetTitleFormat}\label{wxhtmlhelpcontrollersettitleformat}
-IMPORTANT! KeywordSearch searches only pages listed in .htc file(s)!
-(you should have all pages in contents file...)
+\func{void}{SetTitleFormat}{\param{const wxString\& }{format}}
+Sets format of title of the frame. Must contain exactly one "\%s"
+(for title of displayed HTML page).
\membersection{wxHtmlHelpController::UseConfig}\label{wxhtmlhelpcontrolleruseconfig}
If there is associated config object, wxHtmlHelpController automatically
reads and writes settings (including wxHtmlWindow's settings) when needed.
-The only thing you must do is create wxConfig object and call UseConfig.
-
-
-\membersection{wxHtmlHelpController::ReadCustomization}\label{wxhtmlhelpcontrollerreadcustomization}
-
-\func{void}{ReadCustomization}{\param{wxConfigBase* }{cfg}, \param{wxString }{path = wxEmptyString}}
-
-Reads controllers setting (position of window etc.)
+The only thing you must do is create wxConfig object and call UseConfig.
+If you do not use {\it UseConfig}, wxHtmlHelpController will use
+default wxConfig object if available (for details see
+\helpref{wxConfigBase::Get}{wxconfigbaseget} and
+\helpref{wxConfigBase::Set}{wxconfigbaseset}).
