\section{\class{wxHtmlHelpController}}\label{wxhtmlhelpcontroller}
8
{\bf WARNING!} Although this class has an API compatible with other wxWidgets
9
help controllers as documented by \helpref{wxHelpController}{wxhelpcontroller}, it
10
is recommended that you use the enhanced capabilities of wxHtmlHelpController's API.
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 "wxWidgets Reference"). The help controller can handle as
17
many books as you want.
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.
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.
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.

\func{}{wxHtmlHelpController}{\param{int }{style = wxHF\_DEFAULT\_STYLE}}
55
\wxheading{Parameters}
57
{\it style} is combination of these flags:
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
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}}

\membersection{wxHtmlHelpController::AddBook}\label{wxhtmlhelpcontrolleraddbook}
84
\func{bool}{AddBook}{\param{const wxFileName\& }{book\_file}, \param{bool }{show\_wait\_msg}}
86
\func{bool}{AddBook}{\param{const wxString\& }{book\_url}, \param{bool }{show\_wait\_msg}}
88
Adds book (\helpref{.hhp file}{helpformat} - HTML Help Workshop project file) into the list of loaded books.
89
This must be called at least once before displaying any help.
91
{\it book\_file} or {\it book\_url} may be either .hhp file or ZIP archive
92
that contains arbitrary number of .hhp files in
93
top-level directory. This ZIP archive must have .zip or .htb extension
94
(the latter stands for "HTML book"). In other words,
95
{\tt AddBook(wxFileName("help.zip"))}
96
is possible and, in fact, recommended way.
98
\wxheading{Parameters}
100
\docparam{show\_wait\_msg}{If true then a decoration-less window with progress message is displayed.}
101
\docparam{book\_file}{Help book filename. It is recommended to use this prototype
102
instead of the one taking URL, because it is less error-prone.}
103
\docparam{book\_url}{Help book URL (note that syntax of filename and URL is
104
different on most platforms)}
108
Don't forget to install wxFileSystem ZIP handler with
109
{\tt wxFileSystem::AddHandler(new wxZipFSHandler);} before calling this method
110
on a .zip or .htb file!
112
\membersection{wxHtmlHelpController::CreateHelpFrame}\label{wxhtmlhelpcontrollercreatehelpframe}
114
\func{virtual wxHtmlHelpFrame*}{CreateHelpFrame}{\param{wxHtmlHelpData * }{data}}
116
This protected virtual method may be overridden so that the controller
117
uses slightly different frame. See {\it samples/html/helpview} sample for
120
\membersection{wxHtmlHelpController::Display}\label{wxhtmlhelpcontrollerdisplay}
122
\func{void}{Display}{\param{const wxString\& }{x}}
124
Displays page {\it x}. This is THE important function - it is used to display
125
the help in application.
127
You can specify the page in many ways:
129
\begin{itemize}\itemsep=0pt
130
\item as direct filename of HTML document
131
\item as chapter name (from contents) or as a book name
132
\item as some word from index
133
\item even as any word (will be searched)
136
Looking for the page runs in these steps:
138
\begin{enumerate}\itemsep=0pt
139
\item try to locate file named x (if x is for example "doc/howto.htm")
140
\item try to open starting page of book named x
141
\item try to find x in contents (if x is for example "How To ...")
142
\item try to find x in index (if x is for example "How To ...")
143
\item switch to Search panel and start searching
146
\func{void}{Display}{\param{const int }{id}}
148
This alternative form is used to search help contents by numeric IDs.
150
\pythonnote{The second form of this method is named DisplayId in
153
\membersection{wxHtmlHelpController::DisplayContents}\label{wxhtmlhelpcontrollerdisplaycontents}
155
\func{void}{DisplayContents}{\void}
157
Displays help window and focuses contents panel.
159
\membersection{wxHtmlHelpController::DisplayIndex}\label{wxhtmlhelpcontrollerdisplayindex}
161
\func{void}{DisplayIndex}{\void}
163
Displays help window and focuses index panel.
165
\membersection{wxHtmlHelpController::KeywordSearch}\label{wxhtmlhelpcontrollerkeywordsearch}
167
\func{bool}{KeywordSearch}{\param{const wxString\& }{keyword}, \param{wxHelpSearchMode }{mode = wxHELP\_SEARCH\_ALL}}
169
Displays help window, focuses search panel and starts searching. Returns true
170
if the keyword was found. Optionally it searches through the index (mode =
171
wxHELP\_SEARCH\_INDEX), default the content (mode = wxHELP\_SEARCH\_ALL).
173
{\bf Important:} KeywordSearch searches only pages listed in .hhc file(s).
174
You should list all pages in the contents file.
176
\membersection{wxHtmlHelpController::ReadCustomization}\label{wxhtmlhelpcontrollerreadcustomization}
178
\func{void}{ReadCustomization}{\param{wxConfigBase* }{cfg}, \param{wxString }{path = wxEmptyString}}
180
Reads the controller's setting (position of window, etc.)
182
\membersection{wxHtmlHelpController::SetTempDir}\label{wxhtmlhelpcontrollersettempdir}
184
\func{void}{SetTempDir}{\param{const wxString\& }{path}}
186
Sets the path for storing temporary files - cached binary versions of index and contents files. These binary
187
forms are much faster to read. Default value is empty string (empty string means
188
that no cached data are stored). Note that these files are {\it not}
189
deleted when program exits.
191
Once created these cached files will be used in all subsequent executions
192
of your application. If cached files become older than corresponding .hhp
193
file (e.g. if you regenerate documentation) it will be refreshed.
195
\membersection{wxHtmlHelpController::SetTitleFormat}\label{wxhtmlhelpcontrollersettitleformat}
197
\func{void}{SetTitleFormat}{\param{const wxString\& }{format}}
199
Sets format of title of the frame. Must contain exactly one "\%s"
200
(for title of displayed HTML page).
202
\membersection{wxHtmlHelpController::UseConfig}\label{wxhtmlhelpcontrolleruseconfig}
204
\func{void}{UseConfig}{\param{wxConfigBase* }{config}, \param{const wxString\& }{rootpath = wxEmptyString}}
206
Associates {\it config} object with the controller.
208
If there is associated config object, wxHtmlHelpController automatically
209
reads and writes settings (including wxHtmlWindow's settings) when needed.
211
The only thing you must do is create wxConfig object and call UseConfig.
213
If you do not use {\it UseConfig}, wxHtmlHelpController will use
214
default wxConfig object if available (for details see
215
\helpref{wxConfigBase::Get}{wxconfigbaseget} and
216
\helpref{wxConfigBase::Set}{wxconfigbaseset}).
218
\membersection{wxHtmlHelpController::WriteCustomization}\label{wxhtmlhelpcontrollerwritecustomization}
220
\func{void}{WriteCustomization}{\param{wxConfigBase* }{cfg}, \param{wxString }{path = wxEmptyString}}
222
Stores controllers setting (position of window etc.)
