   6 \section{\class{wxHtmlWinParser}}\label{wxhtmlwinparser}
   7
   8 This class is derived from \helpref{wxHtmlParser}{wxhtmlparser} and
   9 its main goal is to parse HTML input so that it can be displayed in
  10 \helpref{wxHtmlWindow}{wxhtmlwindow}. It uses a special
  11 \helpref{wxHtmlWinTagHandler}{wxhtmlwintaghandler}.
  12
  13 \wxheading{Notes}
  14
  15 The product of parsing is a wxHtmlCell (resp. wxHtmlContainer) object.

  34
  35 \func{}{wxHtmlWinParser}{\param{wxHtmlWindow }{*wnd}}
  36
  37 Constructor. Don't use the default one, use constructor with
  38 {\it wnd} parameter ({\it wnd} is pointer to associated \helpref{wxHtmlWindow}{wxhtmlwindow})
  39
  40 \membersection{wxHtmlWinParser::AddModule}\label{wxhtmlwinparseraddmodule}
  41
  42 \func{static void}{AddModule}{\param{wxHtmlTagsModule }{*module}}
  43
  44 Adds \helpref{module}{handlers} to the list of wxHtmlWinParser tag handler.
  45
  46 \membersection{wxHtmlWinParser::CloseContainer}\label{wxhtmlwinparserclosecontainer}
  47
  48 \func{wxHtmlContainerCell*}{CloseContainer}{\void}
  49
  50 Closes the container, sets actual container to the parent one
  51 and returns pointer to it (see \helpref{Overview}{cells}).
  52
  53 \membersection{wxHtmlWinParser::CreateCurrentFont}\label{wxhtmlwinparsercreatecurrentfont}
  54
  55 \func{virtual wxFont*}{CreateCurrentFont}{\void}
  56
  57 Creates font based on current setting (see
  58 \helpref{SetFontSize}{wxhtmlwinparsersetfontsize},
  59 \helpref{SetFontBold}{wxhtmlwinparsersetfontbold},
  60 \helpref{SetFontItalic}{wxhtmlwinparsersetfontitalic},
  61 \helpref{SetFontFixed}{wxhtmlwinparsersetfontfixed},
  62 \helpref{SetFontUnderlined}{wxhtmlwinparsersetfontunderlined})

 165
 166 \constfunc{const wxHtmlLinkInfo\&}{GetLink}{\void}
 167
 168 Returns actual hypertext link. (This value has a non-empty
 169 \helpref{Href}{wxhtmllinkinfogethref} string
 170 if the parser is between {\tt <A>} and {\tt </A>} tags,
 171 wxEmptyString otherwise.)
 172

 184 that is supported by operating system.
 185
 186 \membersection{wxHtmlWinParser::GetWindow}\label{wxhtmlwinparsergetwindow}
 187
 188 \func{wxHtmlWindow*}{GetWindow}{\void}
 189
 190 Returns associated window (wxHtmlWindow). This may be NULL! (You should always
 191 test if it is non-NULL. For example {\tt TITLE} handler sets window
 192 title only if some window is associated, otherwise it does nothing)
 193
 194 \membersection{wxHtmlWinParser::OpenContainer}\label{wxhtmlwinparseropencontainer}
 195
 196 \func{wxHtmlContainerCell*}{OpenContainer}{\void}
 197
 198 Opens new container and returns pointer to it (see \helpref{Overview}{cells}).
 199
 200 \membersection{wxHtmlWinParser::SetActualColor}\label{wxhtmlwinparsersetactualcolor}
 201
 202 \func{void}{SetActualColor}{\param{const wxColour\& }{clr}}
 203
 204 Sets actual text colour. Note: this DOESN'T change the colour!
 205 You must create \helpref{wxHtmlColourCell}{wxhtmlcolourcell} yourself.
 206
 207 \membersection{wxHtmlWinParser::SetAlign}\label{wxhtmlwinparsersetalign}
 208
 209 \func{void}{SetAlign}{\param{int }{a}}
 210
 211 Sets default horizontal alignment (see
 212 \helpref{wxHtmlContainerCell::SetAlignHor}{wxhtmlcontainercellsetalignhor}.)
 213 Alignment of newly opened container is set to this value.
 214
 215 \membersection{wxHtmlWinParser::SetContainer}\label{wxhtmlwinparsersetcontainer}
 216
 217 \func{wxHtmlContainerCell*}{SetContainer}{\param{wxHtmlContainerCell *}{c}}
 218
 219 Allows you to directly set opened container. This is not recommended - you should use OpenContainer
 220 wherever possible.
 221
 222 \membersection{wxHtmlWinParser::SetDC}\label{wxhtmlwinparsersetdc}
 223
 224 \func{virtual void}{SetDC}{\param{wxDC }{*dc}, \param{double }{pixel\_scale = 1.0}}
 225
 226 Sets the DC. This must be called before \helpref{Parse}{wxhtmlparserparse}!
 227 {\it pixel\_scale}  can be used when rendering to high-resolution
 228 DCs (e.g. printer) to adjust size of pixel metrics. (Many dimensions in
 229 HTML are given in pixels -- e.g. image sizes. 300x300 image would be only one
 230 inch wide on typical printer. With pixel\_scale = 3.0 it would be 3 inches.)
 231
 232 \membersection{wxHtmlWinParser::SetFontBold}\label{wxhtmlwinparsersetfontbold}
 233
 234 \func{void}{SetFontBold}{\param{int }{x}}
 235
 236 Sets bold flag of actualfont. {\it x} is either true of false.
 237
 238 \membersection{wxHtmlWinParser::SetFontFace}\label{wxhtmlwinparsersetfontface}
 239
 240 \func{void}{SetFontFace}{\param{const wxString\& }{face}}
 241
 242 Sets current font face to {\it face}. This affects either fixed size
 243 font or proportional, depending on context (whether the parser is
 244 inside {\tt <TT>} tag or not).
 245
 246 \membersection{wxHtmlWinParser::SetFontFixed}\label{wxhtmlwinparsersetfontfixed}
 247
 248 \func{void}{SetFontFixed}{\param{int }{x}}
 249
 250 Sets fixed face flag of actualfont. {\it x} is either true of false.
 251
 252 \membersection{wxHtmlWinParser::SetFontItalic}\label{wxhtmlwinparsersetfontitalic}
 253
 254 \func{void}{SetFontItalic}{\param{int }{x}}
 255
 256 Sets italic flag of actualfont. {\it x} is either true of false.
 257
 258 \membersection{wxHtmlWinParser::SetFontSize}\label{wxhtmlwinparsersetfontsize}
 259
 260 \func{void}{SetFontSize}{\param{int }{s}}
 261
 262 Sets actual font size (HTML size varies from 1 to 7)
 263
 264 \membersection{wxHtmlWinParser::SetFontUnderlined}\label{wxhtmlwinparsersetfontunderlined}
 265
 266 \func{void}{SetFontUnderlined}{\param{int }{x}}
 267
 268 Sets underlined flag of actualfont. {\it x} is either true of false.
 269
 270 \membersection{wxHtmlWinParser::SetFonts}\label{wxhtmlwinparsersetfonts}
 271
 272 \func{void}{SetFonts}{\param{wxString }{normal\_face}, \param{wxString }{fixed\_face}, \param{const int }{*sizes = NULL}}
 273
 274 Sets fonts. See \helpref{wxHtmlWindow::SetFonts}{wxhtmlwindowsetfonts} for
 275 detailed description.
 276
 277 \membersection{wxHtmlWinParser::SetInputEncoding}\label{wxhtmlwinparsersetinputencoding}
 278
 279 \func{void}{SetInputEncoding}{\param{wxFontEncoding }{enc}}
 280
 281 Sets input encoding. The parser uses this information to build conversion
 282 tables from document's encoding to some encoding supported by operating
 283 system.
 284
 285 \membersection{wxHtmlWinParser::SetLink}\label{wxhtmlwinparsersetlink}
 286
 287 \func{void}{SetLink}{\param{const wxHtmlLinkInfo\& }{link}}
 288
 289 Sets actual hypertext link. Empty link is represented
 290 by \helpref{wxHtmlLinkInfo}{wxhtmllinkinfo} with {\it Href} equal
 291 to wxEmptyString.
 292
 293 \membersection{wxHtmlWinParser::SetLinkColor}\label{wxhtmlwinparsersetlinkcolor}
 294
 295 \func{void}{SetLinkColor}{\param{const wxColour\& }{clr}}
 296
 297 Sets colour of hypertext link.
