   6 \section{\class{wxHtmlHelpController}}\label{wxhtmlhelpcontroller}
   7
   8 {\bf WARNING!} Although this class has an API compatible with other wxWindows
   9 help controllers as documented by \helpref{wxHelpController}{wxhelpcontroller}, it
  10 is recommended that you use the enhanced capabilities of wxHtmlHelpController's API.
  11
  12 This help controller provides an easy way of displaying HTML help in your
  13 application (see {\it test} sample). The help system is based on {\bf books}
  14 (see \helpref{AddBook}{wxhtmlhelpcontrolleraddbook}). A book is a logical
  15 section of documentation (for example "User's Guide" or "Programmer's Guide" or
  16 "C++ Reference" or "wxWindows Reference"). The help controller can handle as
  17 many books as you want.
  18
  19 wxHTML uses Microsoft's HTML Help Workshop project files (.hhp, .hhk, .hhc) as its
  20 native format. The file format is described \helpref{here}{helpformat}.
  21 Have a look at docs/html/ directory where sample project files are stored.
  22
  23 You can use Tex2RTF to produce these files when generating HTML, if you set {\bf htmlWorkshopFiles} to {\bf true} in
  24 your tex2rtf.ini file.
  25
  26 \wxheading{Note}
  27
  28 It is strongly recommended to use preprocessed {\bf .hhp.cached} version of
  29 projects. It can be either created on-the-fly (see
  30 \helpref{SetTempDir}{wxhtmlhelpcontrollersettempdir}) or you can use
  31 {\bf hhp2cached} utility from {\it utils/hhp2cached} to create it and
  32 distribute the cached version together with helpfiles. See {\it samples/html/help}
  33 sample for demonstration of its use.

  51 \func{}{wxHtmlHelpController}{\param{int }{style = wxHF\_DEFAULT\_STYLE}}
  52
  53 Constructor.
  54
  55 \wxheading{Parameters}
  56
  57 {\it style} is combination of these flags:
  58
  59 \begin{twocollist}\itemsep=0pt
  60 \twocolitem{\windowstyle{wxHF\_TOOLBAR}}{Help frame has toolbar.}
  61 \twocolitem{\windowstyle{wxHF\_FLAT\_TOOLBAR}}{Help frame has toolbar with flat buttons (aka coolbar).}
  62 \twocolitem{\windowstyle{wxHF\_CONTENTS}}{Help frame has contents panel.}
  63 \twocolitem{\windowstyle{wxHF\_INDEX}}{Help frame has index panel.}
  64 \twocolitem{\windowstyle{wxHF\_SEARCH}}{Help frame has search panel.}
  65 \twocolitem{\windowstyle{wxHF\_BOOKMARKS}}{Help frame has bookmarks controls.}
  66 \twocolitem{\windowstyle{wxHF\_OPEN\_FILES}}{Allow user to open arbitrary HTML document.}
  67 \twocolitem{\windowstyle{wxHF\_PRINT}}{Toolbar contains "print" button.}
  68 \twocolitem{\windowstyle{wxHF\_MERGE\_BOOKS}}{Contents pane does not show
  69 book nodes. All books are merged together and appear as single book to the
  70 user.}
  71 \twocolitem{\windowstyle{wxHF\_ICONS\_BOOK}}{All nodes in contents pane
  72 have a book icon. This is how Microsoft's HTML help viewer behaves.}
  73 \twocolitem{\windowstyle{wxHF\_ICONS\_FOLDER}}{Book nodes in contents pane have
  74 a book icon, book's sections have a folder icon. This is the default.}
  75 \twocolitem{\windowstyle{wxHF\_ICONS\_BOOK\_CHAPTER}}{Both book nodes and
  76 nodes of top-level sections of a book (i.e. chapters) have a book icon,
  77 all other sections (sections, subsections, ...) have a folder icon.}
  78 \twocolitem{\windowstyle{wxHF\_DEFAULT\_STYLE}}{{\tt wxHF\_TOOLBAR | wxHF\_CONTENTS
  79 | wxHF\_INDEX | wxHF\_SEARCH | wxHF\_BOOKMARKS | wxHF\_PRINT}}
  80 \end{twocollist}
  81
  82 \membersection{wxHtmlHelpController::AddBook}\label{wxhtmlhelpcontrolleraddbook}
  83
  84 \func{bool}{AddBook}{\param{const wxString\& }{book}, \param{bool }{show\_wait\_msg}}
  85
  86 Adds book (\helpref{.hhp file}{helpformat} - HTML Help Workshop project file) into the list of loaded books.
  87 This must be called at least once before displaying  any help.
  88
  89 {\it book} may be either .hhp file or ZIP archive that contains arbitrary number of .hhp files in
  90 top-level directory. This ZIP archive must have .zip or .htb extension
  91 (the latter stands for "HTML book"). In other words, {\tt AddBook("help.zip")} is possible and, in fact,
  92 recommended way.
  93
  94 If {\it show\_wait\_msg} is TRUE then a decoration-less window with progress message is displayed.
  95
  96 \wxheading{Note}
  97
  98 Don't forget to install wxFileSystem ZIP handler with
  99 {\tt wxFileSystem::AddHandler(new wxZipFSHandler);} before calling this method
 100 on a .zip or .htb file!
 101
 102 \membersection{wxHtmlHelpController::CreateHelpFrame}\label{wxhtmlhelpcontrollercreatehelpframe}
 103
 104 \func{virtual wxHtmlHelpFrame*}{CreateHelpFrame}{\param{wxHtmlHelpData * }{data}}
 105
 106 This protected virtual method may be overridden so that the controller
 107 uses slightly different frame. See {\it samples/html/helpview} sample for
 108 an example.
 109 \membersection{wxHtmlHelpController::Display}\label{wxhtmlhelpcontrollerdisplay}
 110
 111 \func{void}{Display}{\param{const wxString\& }{x}}
 112
 113 Displays page {\it x}. This is THE important function - it is used to display
 114 the help in application.
 115
 116 You can specify the page in many ways:
 117
 118 \begin{itemize}\itemsep=0pt
 119 \item as direct filename of HTML document
 120 \item as chapter name (from contents) or as a book name
 121 \item as some word from index
 122 \item even as any word (will be searched)
 123 \end{itemize}
 124
 125 Looking for the page runs in these steps:
 126
 127 \begin{enumerate}\itemsep=0pt
 128 \item try to locate file named x (if x is for example "doc/howto.htm")
 129 \item try to open starting page of book named x
 130 \item try to find x in contents (if x is for example "How To ...")
 131 \item try to find x in index (if x is for example "How To ...")
 132 \item switch to Search panel and start searching
 133 \end{enumerate}
 134
 135 \func{void}{Display}{\param{const int }{id}}
 136
 137 This alternative form is used to search help contents by numeric IDs.
 138
 139 \pythonnote{The second form of this method is named DisplayId in
 140 wxPython.}
 141
 142 \membersection{wxHtmlHelpController::DisplayContents}\label{wxhtmlhelpcontrollerdisplaycontents}
 143
 144 \func{void}{DisplayContents}{\void}
 145
 146 Displays help window and focuses contents panel.
 147
 148 \membersection{wxHtmlHelpController::DisplayIndex}\label{wxhtmlhelpcontrollerdisplayindex}
 149
 150 \func{void}{DisplayIndex}{\void}
 151
 152 Displays help window and focuses index panel.
 153
 154 \membersection{wxHtmlHelpController::KeywordSearch}\label{wxhtmlhelpcontrollerkeywordsearch}
 155
 156 \func{bool}{KeywordSearch}{\param{const wxString\& }{keyword}}
 157
 158 Displays help window, focuses search panel and starts searching.
 159 Returns TRUE if the keyword was found.
 160
 161 {\bf Important:} KeywordSearch searches only pages listed in .hhc file(s).
 162 You should list all pages in the contents file.
 163
 164 \membersection{wxHtmlHelpController::ReadCustomization}\label{wxhtmlhelpcontrollerreadcustomization}
 165
 166 \func{void}{ReadCustomization}{\param{wxConfigBase* }{cfg}, \param{wxString }{path = wxEmptyString}}
 167
 168 Reads the controller's setting (position of window, etc.)
 169
 170 \membersection{wxHtmlHelpController::SetTempDir}\label{wxhtmlhelpcontrollersettempdir}
 171
 172 \func{void}{SetTempDir}{\param{const wxString\& }{path}}
 173
 174 Sets the path for storing temporary files - cached binary versions of index and contents files. These binary
 175 forms are much faster to read. Default value is empty string (empty string means
 176 that no cached data are stored). Note that these files are {\it not}
 177 deleted when program exits.
 178
 179 Once created these cached files will be used in all subsequent executions
 180 of your application. If cached files become older than corresponding .hhp
 181 file (e.g. if you regenerate documentation) it will be refreshed.
 182
 183 \membersection{wxHtmlHelpController::SetTitleFormat}\label{wxhtmlhelpcontrollersettitleformat}
 184
 185 \func{void}{SetTitleFormat}{\param{const wxString\& }{format}}
 186
 187 Sets format of title of the frame. Must contain exactly one "\%s"
 188 (for title of displayed HTML page).
 189
 190 \membersection{wxHtmlHelpController::UseConfig}\label{wxhtmlhelpcontrolleruseconfig}
 191
 192 \func{void}{UseConfig}{\param{wxConfigBase* }{config}, \param{const wxString\& }{rootpath = wxEmptyString}}
 193
 194 Associates {\it config} object with the controller.
 195
 196 If there is associated config object, wxHtmlHelpController automatically
 197 reads and writes settings (including wxHtmlWindow's settings) when needed.
 198
 199 The only thing you must do is create wxConfig object and call UseConfig.
 200
 201 If you do not use {\it UseConfig}, wxHtmlHelpController will use
 202 default wxConfig object if available (for details see
 203 \helpref{wxConfigBase::Get}{wxconfigbaseget} and
 204 \helpref{wxConfigBase::Set}{wxconfigbaseset}).
 205
 206 \membersection{wxHtmlHelpController::WriteCustomization}\label{wxhtmlhelpcontrollerwritecustomization}
 207
 208 \func{void}{WriteCustomization}{\param{wxConfigBase* }{cfg}, \param{wxString }{path = wxEmptyString}}
 209
 210 Stores controllers setting (position of window etc.)
