Actually the whole point of this excercise was to try to make a nice pdf file with contents tree and thumbnail pages using pdflatex, but it keeps depleting tex's resources :-( git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@5884 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775

\section{\class{wxEncodingConverter}}\label{wxencodingconverter}
|
|
|
|
This class is capable of converting strings between any two
|
|
8-bit encodings/charsets. It can also convert from/to Unicode (but only
|
|
if you compiled wxWindows with wxUSE\_UNICODE set to 1).
|
|
|
|
\wxheading{Derived from}
|
|
|
|
\helpref{wxObject}{wxobject}

\membersection{wxEncodingConverter::wxEncodingConverter}\label{wxencodingconverterwxencodingconverter}
|
|
|
|
\func{}{wxEncodingConverter}{\void}
|
|
|
|
Constructor.
|
|
|
|
\membersection{wxEncodingConverter::Init}\label{wxencodingconverterinit}
|
|
|
|
\func{bool}{Init}{\param{wxFontEncoding }{input\_enc}, \param{wxFontEncoding }{output\_enc}, \param{int }{method = wxCONVERT\_STRICT}}
|
|
|
|
Initialize convertion. Both output or input encoding may
|
|
be wxFONTENCODING\_UNICODE, but only if wxUSE\_ENCODING is set to 1.
|
|
All subsequent calls to \helpref{Convert()}{wxencodingconverterconvert}
|
|
will interpret its argument
|
|
as a string in {\it input\_enc} encoding and will output string in
|
|
{\it output\_enc} encoding.
|
|
You must call this method before calling Convert. You may call
|
|
it more than once in order to switch to another conversion.
|
|
{\it Method} affects behaviour of Convert() in case input character
|
|
cannot be converted because it does not exist in output encoding:
|
|
|
|
\begin{twocollist}\itemsep=0pt
|
|
\twocolitem{{\bf wxCONVERT\_STRICT}}{follow behaviour of GNU Recode -
|
|
just copy unconvertable characters to output and don't change them
|
|
(its integer value will stay the same)}
|
|
\twocolitem{{\bf wxCONVERT\_SUBSTITUTE}}{try some (lossy) substitutions
|
|
- e.g. replace unconvertable latin capitals with acute by ordinary
|
|
capitals, replace en-dash or em-dash by '-' etc.}
|
|
\end{twocollist}
|
|
|
|
Both modes gurantee that output string will have same length
|
|
as input string.
|
|
|
|
\wxheading{Return value}
|
|
|
|
FALSE if given conversion is impossible, TRUE otherwise
|
|
(conversion may be impossible either if you try to convert
|
|
to Unicode with non-Unicode build of wxWindows or if input
|
|
or output encoding is not supported.)
|
|
|
|
\membersection{wxEncodingConverter::Convert}\label{wxencodingconverterconvert}
|
|
|
|
\func{wxString}{Convert}{\param{const wxString\& }{input}}
|
|
|
|
\func{void}{Convert}{\param{const wxChar* }{input}, \param{wxChar* }{output}}
|
|
|
|
\func{void}{Convert}{\param{wxChar* }{str}}
|
|
|
|
\func{void}{Convert}{\param{const char* }{input}, \param{wxChar* }{output}}
|
|
|
|
Convert input string according to settings passed to \helpref{Init}{wxencodingconverterinit}.
|
|
Note that you must call Init before using Convert!
|
|
|
|
\membersection{wxEncodingConverter::GetPlatformEquivalents}\label{wxencodingconvertergetplatformequivalents}
|
|
|
|
\func{static wxFontEncodingArray}{GetPlatformEquivalents}{\param{wxFontEncoding }{enc}, \param{int }{platform = wxPLATFORM\_CURRENT}}
|
|
|
|
Return equivalents for given font that are used
|
|
under given platform. Supported platforms:
|
|
|
|
\begin{itemize}\itemsep=0pt
|
|
\item wxPLATFORM\_UNIX
|
|
\item wxPLATFORM\_WINDOWS
|
|
\item wxPLATFORM\_OS2
|
|
\item wxPLATFORM\_MAC
|
|
\item wxPLATFORM\_CURRENT
|
|
\end{itemize}
|
|
|
|
wxPLATFORM\_CURRENT means the plaform this binary was compiled for.
|
|
|
|
Examples:
|
|
|
|
\begin{verbatim}
|
|
current platform enc returned value
|
|
----------------------------------------------
|
|
unix CP1250 {ISO8859_2}
|
|
unix ISO8859_2 {ISO8859_2}
|
|
windows ISO8859_2 {CP1250}
|
|
unix CP1252 {ISO8859_1,ISO8859_15}
|
|
\end{verbatim}
|
|
|
|
Equivalence is defined in terms of convertibility:
|
|
2 encodings are equivalent if you can convert text between
|
|
then without loosing information (it may - and will - happen
|
|
that you loose special chars like quotation marks or em-dashes
|
|
but you shouldn't loose any diacritics and language-specific
|
|
characters when converting between equivalent encodings).
|
|
|
|
Remember that this function does {\bf NOT} check for presence of
|
|
fonts in system. It only tells you what are most suitable
|
|
encodings. (It usually returns only one encoding.)
|
|
|
|
\wxheading{Notes}
|
|
|
|
\begin{itemize}\itemsep=0pt
|
|
\item Note that argument {\it enc} itself may be present in the returned array,
|
|
so that you can - as a side effect - detect whether the
|
|
encoding is native for this platform or not.
|
|
\item helpref{Convert}{wxencodingconverterconvert} is not limited to
|
|
converting between equivalent encodings, it can convert between arbitrary
|
|
two encodings.
|
|
\item If {\it enc} is present in returned array, then it is {\bf always} first
|
|
item of it.
|
|
\item Please note that the returned array may not contain any items at all.
|
|
\end{itemize}
|
|
|
|
\membersection{wxEncodingConverter::GetAllEquivalents}\label{wxencodingconvertergetallequivalents}
|
|
|
|
\func{static wxFontEncodingArray}{GetAllEquivalents}{\param{wxFontEncoding }{enc}}
|
|
|
|
Similar to
|
|
\helpref{GetPlatformEquivalents}{wxencodingconvertergetplatformequivalents},
|
|
but this one will return ALL
|
|
equivalent encodings, regardless the platform, and including itself.
|
|
|
|
This platform's encodings are before others in the array. And again, if {\it enc} is in the array,
|
|
it is the very first item in it.
