\section{\class{wxFont}}\label{wxfont} A font is an object which determines the appearance of text. Fonts are used for drawing text to a device context, and setting the appearance of a window's text. \wxheading{Derived from} \helpref{wxGDIObject}{wxgdiobject}\\ \helpref{wxObject}{wxobject} \wxheading{Include files} \wxheading{Constants} \begin{verbatim} enum wxFontEncoding { wxFONTENCODING_SYSTEM = -1, // system default wxFONTENCODING_DEFAULT, // current default encoding // ISO8859 standard defines a number of single-byte charsets wxFONTENCODING_ISO8859_1, // West European (Latin1) wxFONTENCODING_ISO8859_2, // Central and East European (Latin2) wxFONTENCODING_ISO8859_3, // Esperanto (Latin3) wxFONTENCODING_ISO8859_4, // Baltic (old) (Latin4) wxFONTENCODING_ISO8859_5, // Cyrillic wxFONTENCODING_ISO8859_6, // Arabic wxFONTENCODING_ISO8859_7, // Greek wxFONTENCODING_ISO8859_8, // Hebrew wxFONTENCODING_ISO8859_9, // Turkish (Latin5) wxFONTENCODING_ISO8859_10, // Variation of Latin4 (Latin6) wxFONTENCODING_ISO8859_11, // Thai wxFONTENCODING_ISO8859_12, // doesn't exist currently, but put it // here anyhow to make all ISO8859 // consecutive numbers wxFONTENCODING_ISO8859_13, // Baltic (Latin7) wxFONTENCODING_ISO8859_14, // Latin8 wxFONTENCODING_ISO8859_15, // Latin9 (a.k.a.

One of: \twocolwidtha{5cm} \begin{twocollist}\itemsep=0pt \twocolitem{{\bf wxDEFAULT}}{Chooses a default font.} \twocolitem{{\bf wxDECORATIVE}}{A decorative font.} \twocolitem{{\bf wxROMAN}}{A formal, serif font.} \twocolitem{{\bf wxSCRIPT}}{A handwriting font.} \twocolitem{{\bf wxSWISS}}{A sans-serif font.} \twocolitem{{\bf wxMODERN}}{A fixed pitch font.} \end{twocollist}} \docparam{style}{One of {\bf wxNORMAL}, {\bf wxSLANT} and {\bf wxITALIC}.} \docparam{weight}{One of {\bf wxNORMAL}, {\bf wxLIGHT} and {\bf wxBOLD}.} \docparam{underline}{The value can be TRUE or FALSE. At present this has an effect on Windows only.} \docparam{faceName}{An optional string specifying the actual typeface to be used. If the empty string, a default typeface will chosen based on the family.} \docparam{encoding}{An encoding which may be one of \twocolwidtha{5cm} \begin{twocollist}\itemsep=0pt \twocolitem{{\bf wxFONTENCODING\_SYSTEM}}{Default system encoding.} \twocolitem{{\bf wxFONTENCODING\_DEFAULT}}{Default application encoding: this is the encoding set by calls to \helpref{SetDefaultEncoding}{wxfontsetdefaultencoding} and which may be set to, say, KOI8 to create all fonts by default with KOI8 encoding.

Under Windows, only scaleable TrueType fonts are used. See also \helpref{wxDC::SetFont}{wxdcsetfont}, \helpref{wxDC::DrawText}{wxdcdrawtext} and \helpref{wxDC::GetTextExtent}{wxdcgettextextent}. \membersection{wxFont::\destruct{wxFont}} \func{}{\destruct{wxFont}}{\void} Destructor. \wxheading{Remarks} The destructor may not delete the underlying font object of the native windowing system, since wxFont uses a reference counting system for efficiency. Although all remaining fonts are deleted when the application exits, the application should try to clean up all fonts itself. This is because wxWindows cannot know if a pointer to the font object is stored in an application data structure, and there is a risk of double deletion. \membersection{wxFont::GetDefaultEncoding}\label{wxfontgetdefaultencoding} \func{static wxFontEncoding}{GetDefaultEncoding}{\void} Returns the current applications default encoding. \wxheading{See also} \helpref{Font encoding overview}{wxfontencodingoverview}, \helpref{SetDefaultEncoding}{wxfontsetdefaultencoding} \membersection{wxFont::GetFaceName}\label{wxfontgetfacename} \constfunc{wxString}{GetFaceName}{\void} Returns the typeface name associated with the font, or the empty string if there is no typeface information. \wxheading{See also} \helpref{wxFont::SetFaceName}{wxfontsetfacename} \membersection{wxFont::GetFamily}\label{wxfontgetfamily} \constfunc{int}{GetFamily}{\void} Gets the font family.

A suitable font will be found on the end-user's system. If both the family and the facename are specified, wxWindows will first search for the specific face, and then for a font belonging to the same family. \wxheading{See also} \helpref{wxFont::GetFaceName}{wxfontgetfacename}, \helpref{wxFont::SetFamily}{wxfontsetfamily} \membersection{wxFont::SetFamily}\label{wxfontsetfamily} \func{void}{SetFamily}{\param{int}{ family}} Sets the font family. \wxheading{Parameters} \docparam{family}{One of: \twocolwidtha{5cm} \begin{twocollist}\itemsep=0pt \twocolitem{{\bf wxDEFAULT}}{Chooses a default font.} \twocolitem{{\bf wxDECORATIVE}}{A decorative font.} \twocolitem{{\bf wxROMAN}}{A formal, serif font.} \twocolitem{{\bf wxSCRIPT}}{A handwriting font.} \twocolitem{{\bf wxSWISS}}{A sans-serif font.} \twocolitem{{\bf wxMODERN}}{A fixed pitch font.} \end{twocollist}} \wxheading{See also} \helpref{wxFont::GetFamily}{wxfontgetfamily}, \helpref{wxFont::SetFaceName}{wxfontsetfacename} \membersection{wxFont::SetPointSize}\label{wxfontsetpointsize} \func{void}{SetPointSize}{\param{int}{ pointSize}} Sets the point size. \wxheading{Parameters} \docparam{pointSize}{Size in points.} \wxheading{See also} \helpref{wxFont::GetPointSize}{wxfontgetpointsize} \membersection{wxFont::SetStyle}\label{wxfontsetstyle} \func{void}{SetStyle}{\param{int}{ style}} Sets the font style. \wxheading{Parameters} \docparam{style}{One of {\bf wxNORMAL}, {\bf wxSLANT} and {\bf wxITALIC}.} \wxheading{See also} \helpref{wxFont::GetStyle}{wxfontgetstyle} \membersection{wxFont::SetUnderlined}\label{wxfontsetunderlined} \func{void}{SetUnderlined}{\param{const bool}{ underlined}} Sets underlining. \wxheading{Parameters} \docparam{underlining}{TRUE to underline, FALSE otherwise.} \wxheading{See also} \helpref{wxFont::GetUnderlined}{wxfontgetunderlined} \membersection{wxFont::SetWeight}\label{wxfontsetweight} \func{void}{SetWeight}{\param{int}{ weight}} Sets the font weight. \wxheading{Parameters} \docparam{weight}{One of {\bf wxNORMAL}, {\bf wxLIGHT} and {\bf wxBOLD}.} \wxheading{See also} \helpref{wxFont::GetWeight}{wxfontgetweight} \membersection{wxFont::operator $=$}\label{wxfontassignment} \func{wxFont\&}{operator $=$}{\param{const wxFont\& }{font}} Assignment operator, using reference counting. Returns a reference to `this'. \membersection{wxFont::operator $==$}\label{wxfontequals} \func{bool}{operator $==$}{\param{const wxFont\& }{font}} Equality operator. Two fonts are equal if they contain pointers to the same underlying font data. It does not compare each attribute, so two indefontdently-created fonts using the same parameters will fail the test. \membersection{wxFont::operator $!=$}\label{wxfontnotequals} \func{bool}{operator $!=$}{\param{const wxFont\& }{font}} Inequality operator. Two fonts are not equal if they contain pointers to different underlying font data. It does not compare each attribute.
