\section{\class{wxMBConvFile}}\label{wxmbconvfile}
|
|
|
|
This class used to define the class instance
|
|
{\bf wxConvFileName}, but nowadays {\bf wxConvFileName} is
|
|
either of type wxConvLibc (on most platforms) or wxConvUTF8
|
|
(on MacOS X). {\bf wxConvFileName} converts filenames between
|
|
filesystem multibyte encoding and Unicode. {\bf wxConvFileName}
|
|
can also be set to a something else at run-time which is used
|
|
e.g. by wxGTK to use a class which checks the environment
|
|
variable {\bf G\_FILESYSTEM\_ENCODING} indicating that filenames
|
|
should not be interpreted as UTF8 and also for converting
|
|
invalid UTF8 characters (e.g. if there is a filename in iso8859\_1)
|
|
to strings with octal values.
|
|
|
|
Since some platforms (such as Win32) use Unicode in the filenames,
|
|
and others (such as Unix) use multibyte encodings, this class should only
|
|
be used directly if wxMBFILES is defined to 1. A convenience macro,
|
|
wxFNCONV, is defined to wxConvFileName->cWX2MB in this case. You could
|
|
use it like this:
|
|
|
|
\begin{verbatim}
|
|
wxChar *name = wxT("rawfile.doc");
|
|
FILE *fil = fopen(wxFNCONV(name), "r");
|
|
\end{verbatim}
|
|
|
|
(although it would be better to use wxFopen(name, wxT("r")) in this case.)
