A font is an object which determines the appearance of text, primarily
|
||
|
|
when drawing text to a canvas or device context. A font is determined by
|
||
|
|
up to six parameters:
|
||
|
|
|
||
|
|
\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.}
|
||
|
|
\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 MM\_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 canvas will
|
||
|
|
also scale fonts under both environments.}
