\section{\class{wxMBConv}}\label{wxmbconv}
|
|
|
|
This class is the base class of a hierarchy of classes capable of converting
|
|
text strings between multibyte (SBCS or DBCS) encodings and Unicode. It is itself
|
|
a wrapper around the standard libc mbstowcs() and wcstombs() routines, and has
|
|
one predefined instance, {\bf wxConvLibc}.

|
|
|
|
\func{}{wxMBConv}{\void}
|
|
|
|
Constructor.
|
|
|
|
\membersection{wxMBConv::MB2WC}\label{wxmbconvmb2wc}
|
|
|
|
\constfunc{virtual size\_t}{MB2WC}{\param{wchar\_t* }{buf}, \param{const char* }{psz}, \param{size\_t }{n}}
|
|
|
|
Converts from a string {\it psz} in multibyte encoding to Unicode putting the
|
|
output into the buffer {\it buf} of the size {\it n} (in wide characters, not
|
|
bytes). If {\it buf} is {\tt NULL}, nothing is written to it but the length of
|
|
the string which would result from the conversion is calculated and returned.
|
|
Note that this is the length and not size, i.e. the returned value does
|
|
{\bf not} include the trailing NUL. But when the function is called with a
|
|
non-{\tt NULL} buffer, the {\it n} parameter should be the size of the buffer
|
|
and so it {\bf should} take into account the trailing NUL.
|
|
|
|
\wxheading{Parameters}
|
|
|
|
\docparam{buf}{the output buffer, may be {\tt NULL} if the caller is only
|
|
interested in the length of the resulting string}
|
|
|
|
\docparam{psz}{the {\tt NUL}-terminated input string, cannot be {\tt NULL}}
|
|
|
|
\docparam{n}{the size of the output buffer, ignored if {\it buf} is {\tt NULL}}
|
|
|
|
\wxheading{Return value}
|
|
|
|
The length of the converted string.
|
|
|
|
\membersection{wxMBConv::WC2MB}\label{wxmbconvwc2mb}
|
|
|
|
\constfunc{virtual size\_t}{WC2MB}{\param{char* }{buf}, \param{const wchar\_t* }{psz}, \param{size\_t }{n}}
|
|
|
|
Converts from Unicode to multibyte encoding. The semantics of this function
|
|
(including the return value meaning) is the same as for
|
|
\helpref{MB2WC}{wxmbconvmb2wc}.
|
|
|
|
|
|
\membersection{wxMBConv::cMB2WC}\label{wxmbconvcmb2wc}
|
|
|
|
\constfunc{const wxWCharBuffer}{cMB2WC}{\param{const char* }{psz}}
|
|
|
|
Converts from multibyte encoding to Unicode by calling MB2WC,
|
|
allocating a temporary wxWCharBuffer to hold the result.
|
|
|
|
\membersection{wxMBConv::cWC2MB}\label{wxmbconvcwc2mb}
|
|
|
|
\constfunc{const wxCharBuffer}{cWC2MB}{\param{const wchar\_t* }{psz}}
|
|
|
|
Converts from Unicode to multibyte encoding by calling WC2MB,
|
|
allocating a temporary wxCharBuffer to hold the result.
|
|
|
|
\membersection{wxMBConv::cMB2WX}\label{wxmbconvcmb2wx}
|
|
|
|
\constfunc{const char*}{cMB2WX}{\param{const char* }{psz}}
|
|
|
|
\constfunc{const wxWCharBuffer}{cMB2WX}{\param{const char* }{psz}}
|
|
|
|
Converts from multibyte encoding to the current wxChar type
|
|
(which depends on whether wxUSE\_UNICODE is set to 1). If wxChar is char,
|
|
it returns the parameter unaltered. If wxChar is wchar\_t, it returns the
|
|
result in a wxWCharBuffer. The macro wxMB2WXbuf is defined as the correct
|
|
return type (without const).
|
|
|
|
\membersection{wxMBConv::cWX2MB}\label{wxmbconvcwx2mb}
|
|
|
|
\constfunc{const char*}{cWX2MB}{\param{const wxChar* }{psz}}
|
|
|
|
\constfunc{const wxCharBuffer}{cWX2MB}{\param{const wxChar* }{psz}}
|
|
|
|
Converts from the current wxChar type to multibyte encoding. If wxChar is char,
|
|
it returns the parameter unaltered. If wxChar is wchar\_t, it returns the
|
|
result in a wxCharBuffer. The macro wxWX2MBbuf is defined as the correct
|
|
return type (without const).
|
|
|
|
\membersection{wxMBConv::cWC2WX}\label{wxmbconvcwc2wx}
|
|
|
|
\constfunc{const wchar\_t*}{cWC2WX}{\param{const wchar\_t* }{psz}}
|
|
|
|
\constfunc{const wxCharBuffer}{cWC2WX}{\param{const wchar\_t* }{psz}}
|
|
|
|
Converts from Unicode to the current wxChar type. If wxChar is wchar\_t,
|
|
it returns the parameter unaltered. If wxChar is char, it returns the
|
|
result in a wxCharBuffer. The macro wxWC2WXbuf is defined as the correct
|
|
return type (without const).
|
|
|
|
\membersection{wxMBConv::cWX2WC}\label{wxmbconvcwx2wc}
|
|
|
|
\constfunc{const wchar\_t*}{cWX2WC}{\param{const wxChar* }{psz}}
|
|
|
|
\constfunc{const wxWCharBuffer}{cWX2WC}{\param{const wxChar* }{psz}}
|
|
|
|
Converts from the current wxChar type to Unicode. If wxChar is wchar\_t,
|
|
it returns the parameter unaltered. If wxChar is char, it returns the
|
|
result in a wxWCharBuffer. The macro wxWX2WCbuf is defined as the correct
|
|
return type (without const).
