\section{wxFont overview}\label{wxfontoverview}
|
|
|
|
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.}
