\section{\class{wxFontEnumerator}}\label{wxfontenumerator}
 | 
						|
 | 
						|
wxFontEnumerator enumerates either all available fonts on the system or only
 | 
						|
the ones with given attributes - either only fixed-width (suited for use in
 | 
						|
programs such as terminal emulators and the like) or the fonts available in
 | 
						|
the given \helpref{encoding}{wxfontencodingoverview}.
 | 
						|
 | 
						|
To do this, you just have to call one of EnumerateXXX() functions - either 
 | 
						|
\helpref{EnumerateFacenames}{wxfontenumeratorenumeratefacenames} or 
 | 
						|
\helpref{EnumerateEncodings}{wxfontenumeratorenumerateencodings} and the
 | 
						|
corresponding callback (\helpref{OnFacename}{wxfontenumeratoronfacename} or 
 | 
						|
\helpref{OnFontEncoding}{wxfontenumeratoronfontencoding}) will be called
 | 
						|
repeatedly until either all fonts satisfying the specified criteria are
 | 
						|
exhausted or the callback returns false.
 | 
						|
 | 
						|
\wxheading{Virtual functions to override}
 | 
						|
 | 
						|
Either \helpref{OnFacename}{wxfontenumeratoronfacename} or 
 | 
						|
\helpref{OnFontEncoding}{wxfontenumeratoronfontencoding} should be overridden
 | 
						|
depending on whether you plan to call 
 | 
						|
\helpref{EnumerateFacenames}{wxfontenumeratorenumeratefacenames} or 
 | 
						|
\helpref{EnumerateEncodings}{wxfontenumeratorenumerateencodings}. Of course,
 | 
						|
if you call both of them, you should override both functions.

\membersection{wxFontEnumerator::EnumerateFacenames}\label{wxfontenumeratorenumeratefacenames}
 | 
						|
 | 
						|
\func{virtual bool}{EnumerateFacenames}{
 | 
						|
    \param{wxFontEncoding }{encoding = wxFONTENCODING\_SYSTEM},
 | 
						|
    \param{bool }{fixedWidthOnly = false}}
 | 
						|
 | 
						|
Call \helpref{OnFacename}{wxfontenumeratoronfacename} for each font which
 | 
						|
supports given encoding (only if it is not wxFONTENCODING\_SYSTEM) and is of
 | 
						|
fixed width (if \arg{fixedWidthOnly} is true).
 | 
						|
 | 
						|
Calling this function with default arguments will result in enumerating all
 | 
						|
fonts available on the system.
 | 
						|
 | 
						|
 | 
						|
\membersection{wxFontEnumerator::EnumerateEncodings}\label{wxfontenumeratorenumerateencodings}
 | 
						|
 | 
						|
\func{virtual bool}{EnumerateEncodings}{\param{const wxString\& }{font = ""}}
 | 
						|
 | 
						|
Call \helpref{OnFontEncoding}{wxfontenumeratoronfontencoding} for each
 | 
						|
encoding supported by the given font - or for each encoding supported by at
 | 
						|
least some font if {\it font} is not specified.
 | 
						|
 | 
						|
 | 
						|
\membersection{wxFontEnumerator::GetEncodings}\label{wxfontenumeratorgetencodings}
 | 
						|
 | 
						|
\func{static wxArrayString}{GetEncodings}{\param{const wxString\&}{ facename = ""}}
 | 
						|
 | 
						|
Return array of strings containing all encodings found by 
 | 
						|
\helpref{EnumerateEncodings}{wxfontenumeratorenumerateencodings}.
 | 
						|
 | 
						|
 | 
						|
\membersection{wxFontEnumerator::GetFacenames}\label{wxfontenumeratorgetfacenames}
 | 
						|
 | 
						|
\func{static wxArrayString}{GetFacenames}{\param{wxFontEncoding }{encoding = wxFONTENCODING\_SYSTEM}, \param{bool }{fixedWidthOnly = false}}
 | 
						|
 | 
						|
Return array of strings containing all facenames found by 
 | 
						|
\helpref{EnumerateFacenames}{wxfontenumeratorenumeratefacenames}.
 | 
						|
 | 
						|
 | 
						|
\membersection{wxFontEnumerator::IsValidFacename}\label{wxfontenumeratorisvalidfacename}
 | 
						|
 | 
						|
\func{static bool}{IsValidFacename}{\param{const wxString \&}{ facename}}
 | 
						|
 | 
						|
Returns \true if the given string is valid face name, i.e. it's the face name of an installed
 | 
						|
font and it can safely be used with \helpref{wxFont::SetFaceName}{wxfontsetfacename}.
 | 
						|
 | 
						|
 | 
						|
\membersection{wxFontEnumerator::OnFacename}\label{wxfontenumeratoronfacename}
 | 
						|
 | 
						|
\func{virtual bool}{OnFacename}{\param{const wxString\& }{font}}
 | 
						|
 | 
						|
Called by \helpref{EnumerateFacenames}{wxfontenumeratorenumeratefacenames} for
 | 
						|
each match. Return true to continue enumeration or false to stop it.
 | 
						|
 | 
						|
 | 
						|
\membersection{wxFontEnumerator::OnFontEncoding}\label{wxfontenumeratoronfontencoding}
 | 
						|
 | 
						|
\func{virtual bool}{OnFontEncoding}{\param{const wxString\& }{font}, \param{const wxString\& }{encoding}}
 | 
						|
 | 
						|
Called by \helpref{EnumerateEncodings}{wxfontenumeratorenumerateencodings} for
 | 
						|
each match. Return true to continue enumeration or false to stop it.
