+{\bf WARNING!} Although this class has an API compatible with other wxWindows
+help controllers as documented by \helpref{wxHelpController}{wxhelpcontroller}, it
+is recommended that you use the enhanced capabilities of wxHtmlHelpController's API.
-This help controller provides easy way how to display HTML help in your
-application (see {\it test} sample). Whole help system is based on {\bf books}
-(see \helpref{AddBook}{wxhtmlhelpcontrolleraddbook}). A book is logical

+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 "wxWindows Reference"). The help controller can handle as
many books as you want.
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.
+
+\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.

\membersection{wxHtmlHelpController::wxHtmlHelpController}\label{wxhtmlhelpcontrollerwxhtmlhelpcontroller}
-\func{}{wxHtmlHelpController}{\void}
-
+\func{}{wxHtmlHelpController}{\param{int }{style = wxHF\_DEFAULT\_STYLE}}
Constructor.
-
-\membersection{wxHtmlHelpController::SetTitleFormat}\label{wxhtmlhelpcontrollersettitleformat}
-
-\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::SetTempDir}\label{wxhtmlhelpcontrollersettempdir}
-
-\func{void}{SetTempDir}{\param{const wxString\& }{path}}
-
-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!
-
+\wxheading{Parameters}
+
+{\it style} is combination of these flags:
+
+\begin{twocollist}\itemsep=0pt
+\twocolitem{\windowstyle{wxHF\_TOOLBAR}}{Help frame has toolbar.}
+\twocolitem{\windowstyle{wxHF\_FLAT\_TOOLBAR}}{Help frame has toolbar with flat buttons (aka coolbar).}
+\twocolitem{\windowstyle{wxHF\_CONTENTS}}{Help frame has contents panel.}
+\twocolitem{\windowstyle{wxHF\_INDEX}}{Help frame has index panel.}
+\twocolitem{\windowstyle{wxHF\_SEARCH}}{Help frame has search panel.}
+\twocolitem{\windowstyle{wxHF\_BOOKMARKS}}{Help frame has bookmarks controls.}
+\twocolitem{\windowstyle{wxHF\_OPEN\_FILES}}{Allow user to open arbitrary HTML document.}
+\twocolitem{\windowstyle{wxHF\_PRINT}}{Toolbar contains "print" button.}
+\twocolitem{\windowstyle{wxHF\_MERGE\_BOOKS}}{Contents pane does not show
+book nodes. All books are merged together and appear as single book to the
+user.}
+\twocolitem{\windowstyle{wxHF\_ICONS\_BOOK}}{All nodes in contents pane
+have a book icon. This is how Microsoft's HTML help viewer behaves.}
+\twocolitem{\windowstyle{wxHF\_ICONS\_FOLDER}}{Book nodes in contents pane have
+a book icon, book's sections have a folder icon. This is the default.}
+\twocolitem{\windowstyle{wxHF\_ICONS\_BOOK\_CHAPTER}}{Both book nodes and
+nodes of top-level sections of a book (i.e. chapters) have a book icon,
+all other sections (sections, subsections, ...) have a folder icon.}
+\twocolitem{\windowstyle{wxHF\_DEFAULT\_STYLE}}{{\tt wxHF\_TOOLBAR | wxHF\_CONTENTS
+| wxHF\_INDEX | wxHF\_SEARCH | wxHF\_BOOKMARKS | wxHF\_PRINT}}
+\end{twocollist}
\membersection{wxHtmlHelpController::AddBook}\label{wxhtmlhelpcontrolleraddbook}
-\func{bool}{AddBook}{\param{const wxString\& }{book}, \param{bool }{show_wait_msg}}
+\func{bool}{AddBook}{\param{const wxString\& }{book}, \param{bool }{show\_wait\_msg}}
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.
-If {\it show_wait_msg} is TRUE then a decorationless window with progress message is displayed.
+{\it book} 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("help.zip")} is possible and, in fact,
+recommended way.
+
+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 slightly different frame. See {\it samples/html/helpview} sample for
+an example.
\membersection{wxHtmlHelpController::Display}\label{wxhtmlhelpcontrollerdisplay}
\func{void}{Display}{\param{const wxString\& }{x}}
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}}
Displays help window, focuses search panel and starts searching.
Returns TRUE if the keyword was found.
-IMPORTANT! KeywordSearch searches only pages listed in .htc file(s)!
-(you should have all pages in contents file...)
+{\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.
+
+\membersection{wxHtmlHelpController::SetTitleFormat}\label{wxhtmlhelpcontrollersettitleformat}
+
+\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}).
