3 A font is an object which determines the appearance of text. Fonts are
4 used for drawing text to a device context, and setting the appearance of
5 a window's text.

67
68 \docparam{weight}{One of {\bf wxNORMAL}, {\bf wxLIGHT} and {\bf wxBOLD}.}
69
70 \docparam{underline}{The value can be TRUE or FALSE. At present this has an effect on Windows only.}
71
72 \docparam{faceName}{An optional string specifying the actual typeface to be used. If the empty string,
73 a default typeface will chosen based on the family.}
74
75 \docparam{encoding}{An encoding which may be one of
76 \twocolwidtha{5cm}
77 \begin{twocollist}\itemsep=0pt
78 \twocolitem{{\bf wxFONTENCODING\_SYSTEM}}{Default system encoding.}
79 \twocolitem{{\bf wxFONTENCODING\_DEFAULT}}{Default application encoding: this
80 is the encoding set by calls to
81 \helpref{SetDefaultEncoding}{wxfontsetdefaultencoding} and which may be set to,
82 say, KOI8 to create all fonts by default with KOI8 encoding. Initially, the
83 default application encoding is the same as default system encoding.}
84 \twocolitem{{\bf wxFONTENCODING\_ISO8859\_1...15}}{ISO8859 encodings.}

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

90
91 \wxheading{Remarks}
92
93 If the desired font does not exist, the closest match will be chosen.
94 Under Windows, only scaleable TrueType fonts are used.

99 \membersection{wxFont::\destruct{wxFont}}
100
101 \func{}{\destruct{wxFont}}{\void}
102
103 Destructor.
104
105 \wxheading{Remarks}
106
107 The destructor may not delete the underlying font object of the native windowing
108 system, since wxFont uses a reference counting system for efficiency.
109
110 Although all remaining fonts are deleted when the application exits,
111 the application should try to clean up all fonts itself. This is because
112 wxWindows cannot know if a pointer to the font object is stored in an
113 application data structure, and there is a risk of double deletion.
114
115 \membersection{wxFont::GetDefaultEncoding}\label{wxfontgetdefaultencoding}
116
117 \func{static wxFontEncoding}{GetDefaultEncoding}{\void}
118

209
210 \func{void}{SetFaceName}{\param{const wxString\& }{faceName}}

212 Sets the facename for the font.
213
214 \wxheading{Parameters}
215
216 \docparam{faceName}{A valid facename, which should be on the end-user's system.}
217
218 \wxheading{Remarks}
219
220 To avoid portability problems, don't rely on a specific face, but specify the font family
221 instead or as well. A suitable font will be found on the end-user's system. If both the
222 family and the facename are specified, wxWindows will first search for the specific face,
223 and then for a font belonging to the same family.

317
318 \func{bool}{operator $==$}{\param{const wxFont\& }{font}}
319
320 Equality operator. Two fonts are equal if they contain pointers
321 to the same underlying font data. It does not compare each attribute,
322 so two indefontdently-created fonts using the same parameters will

330 to different underlying font data. It does not compare each attribute.
