\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.

\func{}{wxFont}{\void}
|
|

|
|
|
|
Creates a font object.

|
|
|
|
\docparam{pointSize}{Size in points.}
|
|
|
|
\docparam{family}{Font family, a generic way of referring to fonts without specifying actual facename. One of:
|
|
|
|
\twocolwidtha{5cm}

|
\begin{twocollist}\itemsep=0pt

|
|
|
|
\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.}
|
|
|
|
\wxheading{Remarks}
|
|
|
|
If the desired font does not exist, the closest match will be chosen.
|
|
Under Windows, only scaleable TrueType fonts are used.
|
|
|
|
Underlining only works under Windows at present.

|
|
\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 wxBrush 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.
|
|
|
|

\constfunc{wxString}{GetFaceName}{\void}

|
|
|
|
\func{void}{SetFaceName}{\param{const wxString\& }{faceName}}
|
|
|
|
Sets the facename for the font.
|
|
|
|
\wxheading{Parameters}
|
|
|
|
\docparam{faceName}{A valid facename, which should be on the end-user's system.}
|
|
|
|
\wxheading{Remarks}
|
|
|
|
To avoid portability problems, don't rely on a specific face, but specify the font family
|
|
instead or as well. 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.
