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

\membersection{wxHtmlWinParser::wxHtmlWinParser}\label{wxhtmlwinparserwxhtmlwinparser}
\func{}{wxHtmlWinParser}{\void}
\func{}{wxHtmlWinParser}{\param{wxHtmlWindowInterface }{*wndIface}}
Constructor. Don't use the default one, use constructor with
{\it wndIface} parameter ({\it wndIface} is a pointer to interface object for
the associated \helpref{wxHtmlWindow}{wxhtmlwindow} or other HTML rendering
window such as \helpref{wxHtmlListBox}{wxhtmllistbox}).
\membersection{wxHtmlWinParser::AddModule}\label{wxhtmlwinparseraddmodule}
\func{static void}{AddModule}{\param{wxHtmlTagsModule }{*module}}
Adds \helpref{module}{handlers} to the list of wxHtmlWinParser tag handler.
\membersection{wxHtmlWinParser::CloseContainer}\label{wxhtmlwinparserclosecontainer}
\func{wxHtmlContainerCell*}{CloseContainer}{\void}
Closes the container, sets actual container to the parent one
and returns pointer to it (see \helpref{Overview}{cells}).
\membersection{wxHtmlWinParser::CreateCurrentFont}\label{wxhtmlwinparsercreatecurrentfont}
\func{virtual wxFont*}{CreateCurrentFont}{\void}
Creates font based on current setting (see
\helpref{SetFontSize}{wxhtmlwinparsersetfontsize},
\helpref{SetFontBold}{wxhtmlwinparsersetfontbold},
\helpref{SetFontItalic}{wxhtmlwinparsersetfontitalic},
\helpref{SetFontFixed}{wxhtmlwinparsersetfontfixed},
\helpref{SetFontUnderlined}{wxhtmlwinparsersetfontunderlined})
and returns pointer to it.
If the font was already created only a pointer is returned.
\membersection{wxHtmlWinParser::GetActualColor}\label{wxhtmlwinparsergetactualcolor}
\constfunc{const wxColour\&}{GetActualColor}{\void}
Returns actual text colour.

\constfunc{int}{GetAlign}{\void}
Returns default horizontal alignment.
\membersection{wxHtmlWinParser::GetCharHeight}\label{wxhtmlwinparsergetcharheight}
\constfunc{int}{GetCharHeight}{\void}
Returns (average) char height in standard font. It is used as DC-independent metrics.
{\bf Note:} This function doesn't return the {\it actual} height. If you want to
know the height of the current font, call {\tt GetDC -> GetCharHeight()}.
\membersection{wxHtmlWinParser::GetCharWidth}\label{wxhtmlwinparsergetcharwidth}
\constfunc{int}{GetCharWidth}{\void}
Returns average char width in standard font. It is used as DC-independent metrics.
{\bf Note:} This function doesn't return the {\it actual} width. If you want to
know the height of the current font, call {\tt GetDC -> GetCharWidth()}
\membersection{wxHtmlWinParser::GetContainer}\label{wxhtmlwinparsergetcontainer}
\constfunc{wxHtmlContainerCell*}{GetContainer}{\void}
Returns pointer to the currently opened container (see \helpref{Overview}{cells}).
Common use:
\begin{verbatim}
m_WParser -> GetContainer() -> InsertCell(new ...);
\end{verbatim}
\membersection{wxHtmlWinParser::GetDC}\label{wxhtmlwinparsergetdc}
\func{wxDC*}{GetDC}{\void}
Returns pointer to the DC used during parsing.
\membersection{wxHtmlWinParser::GetEncodingConverter}\label{wxhtmlwinparsergetencodingconverter}
\constfunc{wxEncodingConverter *}{GetEncodingConverter}{\void}
Returns \helpref{wxEncodingConverter}{wxencodingconverter} class used
to do conversion between \helpref{input encoding}{wxhtmlwinparsergetinputencoding}
and \helpref{output encoding}{wxhtmlwinparsergetoutputencoding}.
\membersection{wxHtmlWinParser::GetFontBold}\label{wxhtmlwinparsergetfontbold}
\constfunc{int}{GetFontBold}{\void}
Returns true if actual font is bold, false otherwise.
\membersection{wxHtmlWinParser::GetFontFace}\label{wxhtmlwinparsergetfontface}
\constfunc{wxString}{GetFontFace}{\void}
Returns actual font face name.
\membersection{wxHtmlWinParser::GetFontFixed}\label{wxhtmlwinparsergetfontfixed}
\constfunc{int}{GetFontFixed}{\void}
Returns true if actual font is fixed face, false otherwise.
\membersection{wxHtmlWinParser::GetFontItalic}\label{wxhtmlwinparsergetfontitalic}
\constfunc{int}{GetFontItalic}{\void}
Returns true if actual font is italic, false otherwise.
\membersection{wxHtmlWinParser::GetFontSize}\label{wxhtmlwinparsergetfontsize}
\constfunc{int}{GetFontSize}{\void}
Returns actual font size (HTML size varies from -2 to +4)
\membersection{wxHtmlWinParser::GetFontUnderlined}\label{wxhtmlwinparsergetfontunderlined}
\constfunc{int}{GetFontUnderlined}{\void}
Returns true if actual font is underlined, false otherwise.
\membersection{wxHtmlWinParser::GetInputEncoding}\label{wxhtmlwinparsergetinputencoding}
\constfunc{wxFontEncoding}{GetInputEncoding}{\void}
Returns input encoding.
\membersection{wxHtmlWinParser::GetLink}\label{wxhtmlwinparsergetlink}
\constfunc{const wxHtmlLinkInfo\&}{GetLink}{\void}
Returns actual hypertext link. (This value has a non-empty
\helpref{Href}{wxhtmllinkinfogethref} string
if the parser is between {\tt <A>} and {\tt </A>} tags,
wxEmptyString otherwise.)
\membersection{wxHtmlWinParser::GetLinkColor}\label{wxhtmlwinparsergetlinkcolor}
\constfunc{const wxColour\&}{GetLinkColor}{\void}
Returns the colour of hypertext link text.
\membersection{wxHtmlWinParser::GetOutputEncoding}\label{wxhtmlwinparsergetoutputencoding}
\constfunc{wxFontEncoding}{GetOutputEncoding}{\void}
Returns output encoding, i.e. closest match to document's input encoding
that is supported by operating system.
\membersection{wxHtmlWinParser::GetWindow}\label{wxhtmlwinparsergetwindow}
\func{wxHtmlWindow*}{GetWindow}{\void}
Returns associated window (wxHtmlWindow). This may be NULL! (You should always
test if it is non-NULL. For example {\tt TITLE} handler sets window
title only if some window is associated, otherwise it does nothing)
\membersection{wxHtmlWinParser::OpenContainer}\label{wxhtmlwinparseropencontainer}
\func{wxHtmlContainerCell*}{OpenContainer}{\void}
Opens new container and returns pointer to it (see \helpref{Overview}{cells}).
\membersection{wxHtmlWinParser::SetActualColor}\label{wxhtmlwinparsersetactualcolor}
\func{void}{SetActualColor}{\param{const wxColour\& }{clr}}
Sets actual text colour. Note: this DOESN'T change the colour!
You must create \helpref{wxHtmlColourCell}{wxhtmlcolourcell} yourself.
\membersection{wxHtmlWinParser::SetAlign}\label{wxhtmlwinparsersetalign}
\func{void}{SetAlign}{\param{int }{a}}
Sets default horizontal alignment (see
\helpref{wxHtmlContainerCell::SetAlignHor}{wxhtmlcontainercellsetalignhor}.)
Alignment of newly opened container is set to this value.
\membersection{wxHtmlWinParser::SetContainer}\label{wxhtmlwinparsersetcontainer}
\func{wxHtmlContainerCell*}{SetContainer}{\param{wxHtmlContainerCell *}{c}}
Allows you to directly set opened container. This is not recommended - you should use OpenContainer
wherever possible.
\membersection{wxHtmlWinParser::SetDC}\label{wxhtmlwinparsersetdc}
\func{virtual void}{SetDC}{\param{wxDC }{*dc}, \param{double }{pixel\_scale = 1.0}}
Sets the DC. This must be called before \helpref{Parse}{wxhtmlparserparse}!
{\it pixel\_scale} can be used when rendering to high-resolution
DCs (e.g. printer) to adjust size of pixel metrics. (Many dimensions in
HTML are given in pixels -- e.g. image sizes. 300x300 image would be only one
inch wide on typical printer. With pixel\_scale = 3.0 it would be 3 inches.)
\membersection{wxHtmlWinParser::SetFontBold}\label{wxhtmlwinparsersetfontbold}
\func{void}{SetFontBold}{\param{int }{x}}
Sets bold flag of actualfont. {\it x} is either true of false.
\membersection{wxHtmlWinParser::SetFontFace}\label{wxhtmlwinparsersetfontface}
\func{void}{SetFontFace}{\param{const wxString\& }{face}}
Sets current font face to {\it face}. This affects either fixed size
font or proportional, depending on context (whether the parser is
inside {\tt <TT>} tag or not).
\membersection{wxHtmlWinParser::SetFontFixed}\label{wxhtmlwinparsersetfontfixed}
\func{void}{SetFontFixed}{\param{int }{x}}
Sets fixed face flag of actualfont. {\it x} is either true of false.
\membersection{wxHtmlWinParser::SetFontItalic}\label{wxhtmlwinparsersetfontitalic}
\func{void}{SetFontItalic}{\param{int }{x}}
Sets italic flag of actualfont. {\it x} is either true of false.
\membersection{wxHtmlWinParser::SetFontSize}\label{wxhtmlwinparsersetfontsize}
\func{void}{SetFontSize}{\param{int }{s}}
Sets actual font size (HTML size varies from 1 to 7)
\membersection{wxHtmlWinParser::SetFontUnderlined}\label{wxhtmlwinparsersetfontunderlined}
\func{void}{SetFontUnderlined}{\param{int }{x}}
Sets underlined flag of actualfont. {\it x} is either true of false.
\membersection{wxHtmlWinParser::SetFonts}\label{wxhtmlwinparsersetfonts}
\func{void}{SetFonts}{\param{const wxString\& }{normal\_face}, \param{const wxString\& }{fixed\_face}, \param{const int }{*sizes = NULL}}
Sets fonts. See \helpref{wxHtmlWindow::SetFonts}{wxhtmlwindowsetfonts} for
detailed description.
\membersection{wxHtmlWinParser::SetInputEncoding}\label{wxhtmlwinparsersetinputencoding}
\func{void}{SetInputEncoding}{\param{wxFontEncoding }{enc}}
Sets input encoding. The parser uses this information to build conversion
tables from document's encoding to some encoding supported by operating
system.
\membersection{wxHtmlWinParser::SetLink}\label{wxhtmlwinparsersetlink}
\func{void}{SetLink}{\param{const wxHtmlLinkInfo\& }{link}}
Sets actual hypertext link. Empty link is represented
by \helpref{wxHtmlLinkInfo}{wxhtmllinkinfo} with {\it Href} equal
to wxEmptyString.
\membersection{wxHtmlWinParser::SetLinkColor}\label{wxhtmlwinparsersetlinkcolor}
\func{void}{SetLinkColor}{\param{const wxColour\& }{clr}}
Sets colour of hypertext link.
