   7
   8 {\bf WARNING! This help controller has an API incompatible with wxWindows
   9 wxHelpController!}
  10
  11 This help controller provides an easy way of displaying HTML help in your
  12 application (see {\it test} sample). The help system is based on {\bf books}
  13 (see \helpref{AddBook}{wxhtmlhelpcontrolleraddbook}). A book is a logical
  14 section of documentation (for example "User's Guide" or "Programmer's Guide" or
  15 "C++ Reference" or "wxWindows Reference"). The help controller can handle as
  16 many books as you want.
  17
  18 wxHTML uses Microsoft's HTML Help Workshop project files (.hhp, .hhk, .hhc) as its
  19 native format. The file format is described \helpref{here}{helpformat}.
  20 Have a look at docs/html/ directory where sample project files are stored.
  21
  22 You can use Tex2RTF to produce these files when generating HTML, if you set {\bf htmlWorkshopFiles} to {\bf true} in
  23 your tex2rtf.ini file.
  24
  25 In order to use the controller in your application under Windows you must
  26 have the following line in your .rc file:
  27
  28 \begin{verbatim}
  29 #include "wx/html/msw/wxhtml.rc"
  30 \end{verbatim}
  31
  32 \wxheading{Note}
  33
  34 It is strongly recommended to use preprocessed {\bf .hhp.cached} version of
  35 projects. It can be either created on-the-fly (see
  36 \helpref{SetTempDir}{wxhtmlhelpcontrollersettempdir}) or you can use
  37 {\bf hhp2cached} utility from {\it utils/hhp2cached} to create it and
  38 distribute the cached version together with helpfiles. See {\it samples/html/help}
  39 sample for demonstration of its use.

  49 \func{}{wxHtmlHelpController}{\param{int }{style = wxHF\_DEFAULTSTYLE}}
  50
  51 Constructor.
  52
  53 \wxheading{Parameters}
  54
  55 {\it style} is combination of these flags:
  56
  57 \begin{twocollist}
  58 \twocolitem{\windowstyle{wxHF\_TOOLBAR}}{Help frame has toolbar.}
  59 \twocolitem{\windowstyle{wxHF\_CONTENTS}}{Help frame has contents panel.}
  60 \twocolitem{\windowstyle{wxHF\_INDEX}}{Help frame has index panel.}
  61 \twocolitem{\windowstyle{wxHF\_SEARCH}}{Help frame has search panel.}
  62 \twocolitem{\windowstyle{wxHF\_BOOKMARKS}}{Help frame has bookmarks controls.}
  63 \twocolitem{\windowstyle{wxHF\_OPENFILES}}{Allow user to open arbitrary HTML document.}
  64 \twocolitem{\windowstyle{wxHF\_PRINT}}{Toolbar contains "print" button.}
  65 \end{twocollist}
  66
  67 Default value: everything but wxHF\_OPENFILES enabled.

  69 \membersection{wxHtmlHelpController::AddBook}\label{wxhtmlhelpcontrolleraddbook}
  70
  71 \func{bool}{AddBook}{\param{const wxString\& }{book}, \param{bool }{show\_wait\_msg}}
  72
  73 Adds book (\helpref{.hhp file}{helpformat} - HTML Help Workshop project file) into the list of loaded books.
  74 This must be called at least once before displaying  any help.
  75
  76 {\it book} may be either .hhp file or ZIP archive that contains arbitrary number of .hhp files in
  77 top-level directory. This ZIP archive must have .zip or .htb extension
  78 (the latter stands for "HTML book"). In other words, {\tt AddBook("help.zip")} is possible and, in fact,
  79 recommended way.
  80
  81 If {\it show\_wait\_msg} is TRUE then a decorationless window with progress message is displayed.
  82
  83 \membersection{wxHtmlHelpController::Display}\label{wxhtmlhelpcontrollerdisplay}
  84
  85 \func{void}{Display}{\param{const wxString\& }{x}}
  86
  87 Displays page {\it x}. This is THE important function - it is used to display
  88 the help in application.
  89
  90 You can specify the page in many ways:
  91
  92 \begin{itemize}\itemsep=0pt
  93 \item as direct filename of HTML document
  94 \item as chapter name (from contents) or as a book name
  95 \item as some word from index
  96 \item even as any word (will be searched)
  97 \end{itemize}
  98
  99 Looking for the page runs in these steps:
 100
 101 \begin{enumerate}\itemsep=0pt
 102 \item try to locate file named x (if x is for example "doc/howto.htm")
 103 \item try to open starting page of book named x
 104 \item try to find x in contents (if x is for example "How To ...")
 105 \item try to find x in index (if x is for example "How To ...")
 106 \item switch to Search panel and start searching
 107 \end{enumerate}
 108
 109 \func{void}{Display}{\param{const int }{id}}
 110
 111 This alternative form is used to search help contents by numeric IDs.
 112
 113 \pythonnote{The second form of this method is named DisplayId in
 114 wxPython.}
 115
 116 \membersection{wxHtmlHelpController::DisplayContents}\label{wxhtmlhelpcontrollerdisplaycontents}
 117
 118 \func{void}{DisplayContents}{\void}
 119
 120 Displays help window and focuses contents panel.
 121
 122 \membersection{wxHtmlHelpController::DisplayIndex}\label{wxhtmlhelpcontrollerdisplayindex}
 123
 124 \func{void}{DisplayIndex}{\void}
 125
 126 Displays help window and focuses index panel.
 127
 128 \membersection{wxHtmlHelpController::KeywordSearch}\label{wxhtmlhelpcontrollerkeywordsearch}
 129
 130 \func{bool}{KeywordSearch}{\param{const wxString\& }{keyword}}
 131
 132 Displays help window, focuses search panel and starts searching.
 133 Returns TRUE if the keyword was found.
 134
 135 {\bf Important:} KeywordSearch searches only pages listed in .htc file(s).
 136 You should list all pages in the contents file.
 137
 138 \membersection{wxHtmlHelpController::ReadCustomization}\label{wxhtmlhelpcontrollerreadcustomization}
 139
 140 \func{void}{ReadCustomization}{\param{wxConfigBase* }{cfg}, \param{wxString }{path = wxEmptyString}}
 141
 142 Reads the controller's setting (position of window, etc.)
 143
 144 \membersection{wxHtmlHelpController::SetTempDir}\label{wxhtmlhelpcontrollersettempdir}
 145
 146 \func{void}{SetTempDir}{\param{const wxString\& }{path}}
 147
 148 Sets the path for storing temporary files - cached binary versions of index and contents files. These binary
 149 forms are much faster to read. Default value is empty string (empty string means
 150 that no cached data are stored). Note that these files are {\it not}
 151 deleted when program exits.
 152
 153 Once created these cached files will be used in all subsequent executions
 154 of your application. If cached files become older than corresponding .hhp
 155 file (e.g. if you regenerate documentation) it will be refreshed.
 156
 157 \membersection{wxHtmlHelpController::SetTitleFormat}\label{wxhtmlhelpcontrollersettitleformat}
 158
 159 \func{void}{SetTitleFormat}{\param{const wxString\& }{format}}
 160
 161 Sets format of title of the frame. Must contain exactly one "\%s"
 162 (for title of displayed HTML page).
 163
 164 \membersection{wxHtmlHelpController::UseConfig}\label{wxhtmlhelpcontrolleruseconfig}
 165
 166 \func{void}{UseConfig}{\param{wxConfigBase* }{config}, \param{const wxString\& }{rootpath = wxEmptyString}}
 167
 168 Associates {\it config} object with the controller.
 169
 170 If there is associated config object, wxHtmlHelpController automatically
 171 reads and writes settings (including wxHtmlWindow's settings) when needed.
 172
 173 The only thing you must do is create wxConfig object and call UseConfig.
 174
 175 If you do not use {\it UseConfig}, wxHtmlHelpController will use
 176 default wxConfig object if available (for details see
 177 \helpref{wxConfigBase::Get}{wxconfigbaseget} and
 178 \helpref{wxConfigBase::Set}{wxconfigbaseset}).
 179
 180 \membersection{wxHtmlHelpController::WriteCustomization}\label{wxhtmlhelpcontrollerwritecustomization}
 181
 182 \func{void}{WriteCustomization}{\param{wxConfigBase* }{cfg}, \param{wxString }{path = wxEmptyString}}
 183
 184 Stores controllers setting (position of window etc.)
 185
 186 \membersection{wxHtmlHelpController::CreateHelpFrame}\label{wxhtmlhelpcontrollercreatehelpframe}
 187
 188 \func{virtual wxHtmlHelpFrame*}{CreateHelpFrame}{\param{wxHtmlHelpData * }{data}}
 189
 190 This protected virtual method may be overriden so that the controller
 191 uses slightly different frame. See {\it samples/html/helpview} sample for
 192 an example.
