Class: \helpref{wxFont}{wxfont}

A font is an object which determines the appearance of text, primarily
when drawing text to a window or device context. A font is determined by
the following parameters (not all of them have to be specified, of course):

\begin{twocollist}\itemsep=0pt
\twocolitem{Point size}{This is the standard way of referring to text size.}
\twocolitem{Family}{Supported families are:
 {\bf wxDEFAULT, wxDECORATIVE, wxROMAN, wxSCRIPT, wxSWISS, wxMODERN}.
 {\bf wxMODERN} is a fixed pitch font; the others are either fixed or variable pitch.}
\twocolitem{Style}{The value can be {\bf wxNORMAL, wxSLANT} or {\bf wxITALIC}.}
\twocolitem{Weight}{The value can be {\bf wxNORMAL, wxLIGHT} or {\bf wxBOLD}.}
\twocolitem{Underlining}{The value can be TRUE or FALSE.}
\twocolitem{Face name}{An optional string specifying the actual typeface to be used. If NULL,
a default typeface will chosen based on the family.}
\twocolitem{Encoding}{The font encoding (see {\bf wxFONTENCODING\_XXX}
constants and the \helpref{font overview}{wxfontencodingoverview} for more
details)}
\end{twocollist}

Specifying a family, rather than a specific typeface name, ensures a degree of
portability across platforms because a suitable font will be chosen for the
given font family.

Under Windows, the face name can be one of the installed fonts on the user's
system. Since the choice of fonts differs from system to system, either choose
standard Windows fonts, or if allowing the user to specify a face name, store
the family id with any file that might be transported to a different Windows
machine or other platform.

\normalbox{{\bf Note:} There is currently a difference between the appearance
of fonts on the two platforms, if the mapping mode is anything other than
wxMM\_TEXT. Under X, font size is always specified in points. Under MS
Windows, the unit for text is points but the text is scaled according to the
current mapping mode. However, user scaling on a device context will also
scale fonts under both environments.}
