Constructor & Destructor Documentation

a2dFontDcData::a2dFontDcData	(	const wxFont &	font = wxNullFont,
		double	size = 0.0
	)

Constructor.

Parameters

font	Font format. The size of the font is not used and should be set using the next parameter.
size	Size in world coordinates.

Definition at line 439 of file stylebase.cpp.

a2dFontDcData::a2dFontDcData	(	double	size,
		int	family,
		int	style = wxNORMAL,
		int	weight = wxNORMAL,
		const bool	underline = false,
		const wxString &	faceName = wxT( "" ),
		wxFontEncoding	encoding = wxFONTENCODING_DEFAULT
	)

Constructor.

Creates a font object (see font encoding overview, in the wxWidgets documentation, for the meaning of the last parameter).

Parameters

size	Size in world coordinates.
family	Font family, a generic way of referring to fonts without specifying actual facename. One of: wxDEFAULT Chooses a default font. wxDECORATIVE A decorative font. wxROMAN A formal, serif font. wxSCRIPT A handwriting font. wxSWISS A sans-serif font. wxMODERN A fixed pitch font.
style	One of wxNORMAL, wxSLANT and wxITALIC.
weight	One of wxNORMAL, wxLIGHT and wxBOLD.
underline	The value can be true or false. At present this has an effect on Windows and Motif 2.x only.
faceName	An optional string specifying the actual typeface to be used. If the empty string, a default typeface will chosen based on the family.
encoding	An encoding which may be one of wxFONTENCODING_SYSTEM Default system encoding. wxFONTENCODING_DEFAULT Default application encoding. wxFONTENCODING_ISO8859_1...15 ISO8859 encodings. wxFONTENCODING_KOI8 The standard Russian encoding for Internet. wxFONTENCODING_CP1250...1252 Windows encodings similar to ISO8859 (but not identical).

If the specified encoding isn't available, no font is created.

wxFONTENCODING_DEFAULT is the encoding set by calls to SetDefaultEncoding and which may be set to, say, KOI8 to create all fonts by default with KOI8 encoding. Initially, the default application encoding is the same as default system encoding.

Remarks

• If the desired font does not exist, the closest match will be chosen.
• Under Windows, only scalable TrueType fonts are used.

Member Function Documentation

wxString a2dFontDcData::FindFileName

(

)

const

Find the filename of the current font.

Currently only implemented for Windows.

Returns

The absolute filename. In case of error an empty string is returned

Definition at line 662 of file stylebase.cpp.

wxFont& a2dFontDcData::GetFont ( void  )

inline

Get the font format.

Returns

The font information. The size of the font should be disregarded, since it is internally for storage.

Definition at line 367 of file stylebase.cpp.

double a2dFontDcData::GetKerning ( wxChar  c1, wxChar  c2  ) const

virtual

Get kerning space between two characters.

Kerning is a method, which moves characters closer together/further apart, to improve the look of the font. Eg. the letter combination LT will be moved closer together. The return value is negative or positive, to respectively move characters closer together, or further apart.

Reimplemented from a2dFontRefData.

Definition at line 722 of file stylebase.cpp.

void a2dFontDcData::SetFont

(

const wxFont &

font

)

Set font format.

Parameters

font	The font information. The size of the font is not used.

Definition at line 504 of file stylebase.cpp.
