Inheritance diagram for wxHtmlWinParser:

Detailed Description

This class is derived from wxHtmlParser and its main goal is to parse HTML input so that it can be displayed in wxHtmlWindow.

It uses a special wxHtmlWinTagHandler.

Note: The product of parsing is a wxHtmlCell (resp. wxHtmlContainer) object.

Library: wxHTML

Category: HTML

Constructor & Destructor Documentation

wxHtmlWinParser::wxHtmlWinParser ( wxHtmlWindowInterface * wndIface = NULL )

Constructor.

Don't use the default one, use the constructor with wndIface parameter (wndIface is a pointer to interface object for the associated wxHtmlWindow or other HTML rendering window such as wxHtmlListBox).

Member Function Documentation

static void wxHtmlWinParser::AddModule ( wxHtmlTagsModule * module )

static

Adds module() to the list of wxHtmlWinParser tag handler.

wxHtmlContainerCell* wxHtmlWinParser::CloseContainer ( )

Closes the container, sets actual container to the parent one and returns pointer to it (see Cells and Containers).

virtual wxFont* wxHtmlWinParser::CreateCurrentFont ( )

virtual

Creates font based on current setting (see SetFontSize(), SetFontBold(), SetFontItalic(), SetFontFixed(), wxHtmlWinParser::SetFontUnderlined) and returns pointer to it.

If the font was already created only a pointer is returned.

const wxColour& wxHtmlWinParser::GetActualColor ( ) const

Returns actual text colour.

int wxHtmlWinParser::GetAlign ( ) const

Returns default horizontal alignment.

int wxHtmlWinParser::GetCharHeight ( ) const

Returns (average) char height in standard font.

It is used as DC-independent metrics.

Note: This function doesn't return the actual height. If you want to know the height of the current font, call GetDC->GetCharHeight().

int wxHtmlWinParser::GetCharWidth ( ) const

Returns average char width in standard font.

It is used as DC-independent metrics.

Note: This function doesn't return the actual width. If you want to know the height of the current font, call GetDC->GetCharWidth().

wxHtmlContainerCell* wxHtmlWinParser::GetContainer ( ) const

Returns pointer to the currently opened container (see Cells and Containers).

Common use:

m_WParser -> GetContainer() -> InsertCell(new ...);

wxDC* wxHtmlWinParser::GetDC ( )

Returns pointer to the DC used during parsing.

wxEncodingConverter* wxHtmlWinParser::GetEncodingConverter ( ) const

Returns wxEncodingConverter class used to do conversion between the input encoding and the output encoding.

int wxHtmlWinParser::GetFontBold ( ) const

Returns true if actual font is bold, false otherwise.

wxString wxHtmlWinParser::GetFontFace ( ) const

Returns actual font face name.

int wxHtmlWinParser::GetFontFixed ( ) const

Returns true if actual font is fixed face, false otherwise.

int wxHtmlWinParser::GetFontItalic ( ) const

Returns true if actual font is italic, false otherwise.

int wxHtmlWinParser::GetFontSize ( ) const

Returns actual font size (HTML size varies from -2 to +4)

int wxHtmlWinParser::GetFontUnderlined ( ) const

Returns true if actual font is underlined, false otherwise.

wxFontEncoding wxHtmlWinParser::GetInputEncoding ( ) const

Returns input encoding.

const wxHtmlLinkInfo& wxHtmlWinParser::GetLink ( ) const

Returns actual hypertext link.

(This value has a non-empty wxHtmlLinkInfo::GetHref Href string if the parser is between <A> and </A> tags, wxEmptyString otherwise.)

const wxColour& wxHtmlWinParser::GetLinkColor ( ) const

Returns the colour of hypertext link text.

wxFontEncoding wxHtmlWinParser::GetOutputEncoding ( ) const

Returns output encoding, i.e.

closest match to document's input encoding that is supported by operating system.

wxHtmlWindowInterface* wxHtmlWinParser::GetWindowInterface ( )

Returns associated window (wxHtmlWindow).

This may be NULL! (You should always test if it is non-NULL. For example TITLE handler sets window title only if some window is associated, otherwise it does nothing.

wxHtmlContainerCell* wxHtmlWinParser::OpenContainer ( )

Opens new container and returns pointer to it (see Cells and Containers).

void wxHtmlWinParser::SetActualColor ( const wxColour & clr )

Sets actual text colour.

Note: this DOESN'T change the colour! You must create wxHtmlColourCell yourself.

void wxHtmlWinParser::SetAlign ( int a )

Sets default horizontal alignment (see wxHtmlContainerCell::SetAlignHor).

Alignment of newly opened container is set to this value.

wxHtmlContainerCell* wxHtmlWinParser::SetContainer ( wxHtmlContainerCell * c )

Allows you to directly set opened container.

This is not recommended - you should use OpenContainer() wherever possible.

virtual void wxHtmlWinParser::SetDC	(	wxDC *	dc,
		double	pixel_scale = `1.0e+0`
	)

virtual

Sets the DC.

This must be called before wxHtmlParser::Parse!

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.)

void wxHtmlWinParser::SetFontBold ( int x )

Sets bold flag of actualfont.

x is either true of false.

void wxHtmlWinParser::SetFontFace ( const wxString & face )

Sets current font face to face.

This affects either fixed size font or proportional, depending on context (whether the parser is inside <TT> tag or not).

void wxHtmlWinParser::SetFontFixed ( int x )

Sets fixed face flag of actualfont.

x is either true of false.

void wxHtmlWinParser::SetFontItalic ( int x )

Sets italic flag of actualfont.

x is either true of false.

void wxHtmlWinParser::SetFonts	(	const wxString &	normal_face,
		const wxString &	fixed_face,
		const int *	sizes = `0`
	)

Sets fonts.

See wxHtmlWindow::SetFonts for detailed description.

void wxHtmlWinParser::SetFontSize ( int s )

Sets actual font size (HTML size varies from 1 to 7).

void wxHtmlWinParser::SetFontUnderlined ( int x )

Sets underlined flag of actualfont.

x is either true of false.

void wxHtmlWinParser::SetInputEncoding ( 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.

void wxHtmlWinParser::SetLink ( const wxHtmlLinkInfo & link )

Sets actual hypertext link.

Empty link is represented by wxHtmlLinkInfo with Href equal to wxEmptyString.

void wxHtmlWinParser::SetLinkColor ( const wxColour & clr )

Sets colour of hypertext link.
