In wxWindows this class manages message catalogs which contain the translations
of the strings used to the current language.
-\perlnote{In wxPerl the {\tt Wx} module exports a '_' function
-that corresponds to the '_' C++ macro.
+\perlnote{In wxPerl you can't use the '\_' function name, so
+the {\tt Wx::Locale} module can export the {\tt gettext} and
+{\tt gettext\_noop} under any given name.
\begin{verbatim}
- use Wx qw(_);
+ # this imports gettext ( equivalent to Wx::GetTranslation
+ # and gettext_noop ( a noop )
+ # into your module
+ use Wx::Locale qw(:default);
# ....
- print _( ``Panic!'' );
+ # use the functions
+ print gettext( ``Panic!'' );
- my( \$button ) = Wx::Button->new( \$window, -1, _( ``Label'' ) );
+ button = Wx::Button->new( window, -1, gettext( ``Label'' ) );
+\end{verbatim}
+If you need to translate a lot of strings, then adding gettext( ) around
+each one is a long task ( that is why \_( ) was introduced ), so just choose
+a shorter name for gettext:
+\begin{verbatim}
+ #
+ use Wx::Locale 'gettext' => 't',
+ 'gettext_noop' => 'gettext_noop';
+
+ # ...
+
+ # use the functions
+ print t( ``Panic!!'' );

\membersection{wxLocale::wxLocale}\label{wxlocaledefctor}
\func{}{wxLocale}{\void}
This is the default constructor and it does nothing to initialize the object:
\helpref{Init()}{wxlocaleinit} must be used to do that.
+\func{}{wxLocale}{\param{int }{language}, \param{int }{flags =
+ wxLOCALE\_LOAD\_DEFAULT | wxLOCALE\_CONV\_ENCODING}}
+
+See \helpref{Init()}{wxlocaleinit} for parameters description.

\func{}{wxLocale}{\param{const char }{*szName}, \param{const char }{*szShort = NULL}, \param{const char }{*szLocale = NULL}, \param{bool }{bLoadDefault = TRUE}, \param{bool }{bConvertEncoding = FALSE}}
-The parameters have the following meaning:
-\begin{itemize}\itemsep=0pt
-\item szName is the name of the locale and is only used in diagnostic messages
-\item szShort is the standard 2 letter locale abbreviation and is used as the
-directory prefix when looking for the message catalog files
-\item szLocale is the parameter for the call to setlocale()
-\item bLoadDefault may be set to FALSE to prevent loading of the message catalog
-for the given locale containing the translations of standard wxWindows messages.
-This parameter would be rarely used in normal circumstances.
-\item bConvertEncoding may be set to TRUE to do automatic conversion of message
-catalogs to platform's native encoding. Note that it will do only basic
-conversion between well-known pair like iso8859-1 and windows-1252 or
-iso8859-2 and windows-1250.
-See \helpref{Writing non-English applications}{nonenglishoverview} for detailed
-description of this behaviour.
-\end{itemize}
+See \helpref{Init()}{wxlocaleinit} for parameters description.
The call of this function has several global side effects which you should
understand: first of all, the application locale is changed - note that this
application and so all subsequent calls to wxGetTranslation() will try to
translate the messages using the message catalogs for this locale.
+
\membersection{wxLocale::\destruct{wxLocale}}\label{wxlocaledtor}
\func{}{\destruct{wxLocale}}{\void}
This only applies to subsequent invocations of AddCatalog()!
+\membersection{wxLocale::AddLanguage}\label{wxlocaleaddlanguage}
+
+\func{static void}{AddLanguage}{\param{const wxLanguageInfo\& }{info}}
+
+Adds custom, user-defined language to the database of known languages. This
+database is used in conjuction with the first form of
+\helpref{Init}{wxlocaleinit}.
+
+wxLanguageInfo is defined as follows:
+
+\begin{verbatim}
+struct WXDLLEXPORT wxLanguageInfo
+{
+ int Language; // wxLanguage id
+ wxString CanonicalName; // Canonical name, e.g. fr_FR
+#ifdef __WIN32__
+ wxUint32 WinLang, WinSublang; // Win32 language identifiers
+ // (LANG_xxxx, SUBLANG_xxxx)
+#endif
+ wxString Description; // human-readable name of the language
+};
+\end{verbatim}
+
+
+{\it Language} should be greater than wxLANGUAGE\_USER\_DEFINED.

+
+
+\membersection{wxLocale::GetCanonicalName}\label{wxlocalegetcanonicalname}
+
+\constfunc{wxString}{GetSysName}{\void}
+
+Returns the canonical form of current locale name. Canonical form is the
+one that is used on UNIX systems: it is a two- or five-letter string in xx or
+xx\_YY format, where xx is ISO 639 code of language and YY is ISO 3166 code of
+the country. Examples are "en", "en\_GB", "en\_US" or "fr\_FR".
+
+This form is internally used when looking up message catalogs.
+
+Compare \helpref{GetSysName}{wxlocalegetsysname}.
+
+
+
+\membersection{wxLocale::GetLanguage}\label{wxlocalegetlanguage}
+
+\constfunc{int}{GetLanguage}{\void}
+
+Returns \helpref{wxLanguage}{wxlanguage} constant of current language.
+Note that you can call this function only if you used the form of
+\helpref{Init}{wxlocaleinit} that takes wxLanguage argument.
+
+
\membersection{wxLocale::GetLocale}\label{wxlocalegetlocale}
\constfunc{const char*}{GetLocale}{\void}
Returns the locale name as passed to the constructor or
-\helpref{Init()}{wxlocaleinit}.
+\helpref{Init()}{wxlocaleinit}. This is full, human-readable name,
+e.g. "English" or "French".
+
\membersection{wxLocale::GetName}\label{wxlocalegetname}
Domains are searched in the last to first order, i.e. catalogs
added later override those added before.
+\membersection{wxLocale::GetSysName}\label{wxlocalegetsysname}
+
+\constfunc{wxString}{GetSysName}{\void}
+
+Returns current platform-specific locale name as passed to setlocale().
+
+Compare \helpref{GetCanonicalName}{wxlocalegetcanonicalname}.
+
+
+\membersection{wxLocale::GetSystemEncoding}\label{wxlocalegetsystemencoding}
+
+\constfunc{static wxFontEncoding}{GetSystemEncoding}{\void}
+
+Tries to detect the user's default font encoding.
+Returns \helpref{wxFontEncoding}{wxfont} value or
+{\bf wxFONTENCODING\_SYSTEM} if it couldn't be determined.
+
+\membersection{wxLocale::GetSystemEncodingName}\label{wxlocalegetsystemencodingname}
+
+\constfunc{static wxString}{GetSystemEncodingName}{\void}
+
+Tries to detect the name of the user's default font encoding. This string isn't
+particularly useful for the application as its form is platform-dependent and
+so you should probably use
+\helpref{GetSystemEncoding}{wxlocalegetsystemencoding} instead.
+
+Returns a user-readable string value or an empty string if it couldn't be
+determined.
+
+\membersection{wxLocale::GetSystemLanguage}\label{wxlocalegetsystemlanguage}
+
+\constfunc{static int}{GetSystemLanguage}{\void}
+
+Tries to detect the user's default language setting.
+Returns \helpref{wxLanguage}{wxlanguage} value or
+ {\bf wxLANGUAGE\_UNKNOWN} if the language-guessing algorithm failed.
