   6 \section{\class{wxHtmlWindow}}\label{wxhtmlwindow}
   7
   8 wxHtmlWindow is probably the only class you will directly use
   9 unless you want to do something special (like adding new tag
  10 handlers or MIME filters).
  11
  12 The purpose of this class is to display HTML pages (either local
  13 file or downloaded via HTTP protocol) in a window. The width
  14 of the window is constant - given in the constructor - and virtual height
  15 is changed dynamically depending on page size.
  16 Once the window is created you can set its content by calling
  17 \helpref{SetPage(text)}{wxhtmlwindowsetpage} or
  18 \helpref{LoadPage(filename)}{wxhtmlwindowloadpage}.

  48 filters. These filters are present by default:
  49
  50 \begin{itemize}\itemsep=0pt
  51 \item {\tt text/html} MIME type
  52 \item {\tt image/*} MIME types
  53 \item Plain Text filter (this filter is used if no other filter matches)

 104
 105 \func{bool}{LoadPage}{\param{const wxString\& }{location}}
 106
 107 Unlike SetPage this function first loads HTML page from {\it location}
 108 and then displays it. See example:
 109
 110 \begin{verbatim}
 111 htmlwin -> SetPage("help/myproject/index.htm");
 112 \end{verbatim}
 113
 114 \wxheading{Parameters}

 117
 118 \wxheading{Return value}
 119
 120 FALSE if an error occured, TRUE otherwise
 121
 122 \membersection{wxHtmlWindow::OnLinkClicked}\label{wxhtmlwindowonlinkclicked}
 123
 124 \func{virtual void}{OnLinkClicked}{\param{const wxHtmlLinkInfo& }{link}}
 125
 126 Called when user clicks on hypertext link. Default behaviour is to call

 128
 129 Also see \helpref{wxHtmlLinkInfo}{wxhtmllinkinfo}.
 130
 131
 132 \membersection{wxHtmlWindow::OnSetTitle}\label{wxhtmlwindowonsettitle}
 133
 134 \func{virtual void}{OnSetTitle}{\param{const wxString\& }{title}}
 135
 136 Called on parsing {\tt <TITLE>} tag.
 137
 138
 139 \membersection{wxHtmlWindow::ReadCustomization}\label{wxhtmlwindowreadcustomization}
 140
 141 \func{virtual void}{ReadCustomization}{\param{wxConfigBase }{*cfg}, \param{wxString }{path = wxEmptyString}}
 142
 143 This reads custom settings from wxConfig. It uses the path 'path'
 144 if given, otherwise it saves info into currently selected path.
 145 The values are stored in sub-path {\tt wxHtmlWindow}
 146
 147 Read values: all things set by SetFonts, SetBorders.
 148
 149 \wxheading{Parameters}
 150
 151 \docparam{cfg}{wxConfig from which you want to read the configuration.}
 152
 153 \docparam{path}{Optional path in config tree. If not given current path is used.}
 154
 155 \membersection{wxHtmlWindow::SetBorders}\label{wxhtmlwindowsetborders}
 156
 157 \func{void}{SetBorders}{\param{int }{b}}
 158
 159 This function sets the space between border of window and HTML contents. See image:
 160
 161 \helponly{\image{}{border.bmp}}
 162
 163 \wxheading{Parameters}
 164
 165 \docparam{b}{indentation from borders in pixels}
 166
 167 \membersection{wxHtmlWindow::SetFonts}\label{wxhtmlwindowsetfonts}
 168
 169 \func{void}{SetFonts}{\param{wxString }{normal\_face}, \param{wxString }{fixed\_face}, \param{const int }{*sizes}}
 170
 171 This function sets font sizes and faces.
 172
 173 \wxheading{Parameters}
 174
 175 \docparam{normal\_face}{This is face name for normal (i.e. non-fixed) font.
 176 It can be either empty string (then the default face is choosen) or
 177 platform-specific face name. Examples are "helvetica" under Unix or
 178 "Times New Roman" under Windows.}
 179
 180 \docparam{fixed\_face}{The same thing for fixed face ( <TT>..</TT> )}
 181
 182 \docparam{sizes}{This is an array of 7 items of {\it int} type.
 183 The values represent size of font with HTML size from -2 to +4
 184 ( <FONT SIZE=-2> to <FONT SIZE=+4> )}
 185
 186 \wxheading{Defaults}
 187
 188 Under wxGTK:
 189
 190 \begin{verbatim}
 191     SetFonts("", "", {10, 12, 14, 16, 19, 24, 32});
 192 \end{verbatim}
 193
 194 Under Windows:
 195
 196 \begin{verbatim}
 197     SetFonts("", "", {7, 8, 10, 12, 16, 22, 30});
 198 \end{verbatim}
 199
 200 Athough it seems different the fact is that the fonts are of approximately
 201 same size under both platforms (due to wxMSW / wxGTK inconsistency)
 202

 204
 205 \func{bool}{SetPage}{\param{const wxString\& }{source}}

 230 frame title, e.g. "HtmlHelp : \%s". It must contain exactly one \%s. This
 231 \%s is substituted with HTML page title.
 232
 233 \membersection{wxHtmlWindow::SetRelatedStatusBar}\label{wxhtmlwindowsetrelatedstatusbar}
 234
 235 \func{void}{SetRelatedStatusBar}{\param{int }{bar}}
 236
 237 {\bf After} calling \helpref{SetRelatedFrame}{wxhtmlwindowsetrelatedframe},
 238 this sets statusbar slot where messages will be displayed.
