 421
 422     In wxWidgets this class manages message catalogs which contain the translations
 423     of the strings used to the current language.
 424
 425     For a list of the supported languages, please see ::wxLanguage enum values.
 426     These constants may be used to specify the language in wxLocale::Init and

 428
 429     @beginWxPerlOnly
 430     In wxPerl you can't use the '_' function name, so
 431     the @c Wx::Locale module can export the @c gettext and
 432     @c gettext_noop under any given name.
 433
 434     @code
 435       # this imports gettext ( equivalent to Wx::GetTranslation
 436       # and gettext_noop ( a noop )
 437       # into your module
 438       use Wx::Locale qw(:default);

 447
 448     If you need to translate a lot of strings, then adding gettext( ) around
 449     each one is a long task ( that is why _( ) was introduced ), so just choose
 450     a shorter name for gettext:
 451
 452     @code
 453       use Wx::Locale 'gettext' = 't',
 454                      'gettext_noop' = 'gettext_noop';

 912     @note This function is not suitable for literal strings in Unicode builds
 913           since the literal strings must be enclosed into _T() or wxT() macro
 914           which makes them unrecognised by @c xgettext, and so they are not
 915           extracted to the message catalog. Instead, use the _() and wxPLURAL()
 916           macro for all literal strings.

 926     This is an overloaded version of
 927     wxGetTranslation(const wxString&, const wxString&), please see its
 928     documentation for general information.
 929
 930     This version is used when retrieving translation of string that has
 931     different singular and plural forms in English or different plural forms in
 932     some other language. Like wxGetTranslation(const wxString&,const wxString&),
 933     the @a string parameter must contain the singular form of the string to be
 934     converted and is used as the key for the search in the catalog. The
 935     @a plural parameter is the plural form (in English). The parameter @a n is
 936     used to determine the plural form. If no message catalog is found,
 937     @a string is returned if "n == 1", otherwise @a plural is returned.
 938
 939     See GNU gettext Manual for additional information on plural forms handling:
 940     <http://www.gnu.org/software/gettext/manual/gettext.html#Plural-forms>
 941     For a shorter alternative see the wxPLURAL() macro.
 942
 943     This function calls wxLocale::GetString().
