295 wxLocale class encapsulates all language-dependent settings and is a
296 generalization of the C locale concept.
298 In wxWidgets this class manages message catalogs which contain the translations
299 of the strings used to the current language.
301 For a list of the supported languages, please see ::wxLanguage enum values.
302 These constants may be used to specify the language in wxLocale::Init and
303 are returned by wxLocale::GetSystemLanguage.
306 In wxPerl you can't use the '_' function name, so
307 the @c Wx::Locale module can export the @c gettext and
308 @c gettext_noop under any given name.
311 # this imports gettext ( equivalent to Wx::GetTranslation
312 # and gettext_noop ( a noop )
314 use Wx::Locale qw(:default);
319 print gettext( "Panic!" );
321 button = Wx::Button-new( window, -1, gettext( "Label" ) );
324 If you need to translate a lot of strings, then adding gettext( ) around
325 each one is a long task ( that is why _( ) was introduced ), so just choose
326 a shorter name for gettext:
329 use Wx::Locale 'gettext' = 't',
330 'gettext_noop' = 'gettext_noop';
335 print t( "Panic!!" );
344 @see @ref overview_i18n, @ref page_samples_internat, wxXLocale
350 This is the default constructor and it does nothing to initialize the object:
351 Init() must be used to do that.
356 See Init() for parameters description.
358 wxLocale(int language
,
359 int flags
= wxLOCALE_LOAD_DEFAULT
| wxLOCALE_CONV_ENCODING
);
362 See Init() for parameters description.
364 The call of this function has several global side effects which you should
365 understand: first of all, the application locale is changed - note that this
366 will affect many of standard C library functions such as printf() or strftime().
367 Second, this wxLocale object becomes the new current global locale for the
368 application and so all subsequent calls to ::wxGetTranslation() will try to
369 translate the messages using the message catalogs for this locale.
371 wxLocale(const wxString
& name

372 const wxString
& short = wxEmptyString
,
373 const wxString
& locale
= wxEmptyString
,
374 bool bLoadDefault
= true,
375 bool bConvertEncoding
= false);
378 The destructor, like the constructor, also has global side effects: the
379 previously set locale is restored and so the changes described in
380 Init() documentation are rolled back.
385 Add a catalog for use with the current locale: it is searched for in standard
386 places (current directory first, then the system one), but you may also prepend
387 additional directories to the search path with AddCatalogLookupPathPrefix().
389 All loaded catalogs will be used for message lookup by GetString() for
392 In this overload, @c msgid strings are assumed
393 to be in English and written only using 7-bit ASCII characters.
394 If you have to deal with non-English strings or 8-bit characters in the
395 source code, see the instructions in @ref overview_nonenglish.
398 @true if catalog was successfully loaded, @false otherwise (which might
399 mean that the catalog is not found or that it isn't in the correct format).

404 Add a catalog for use with the current locale: it is searched for in standard
405 places (current directory first, then the system one), but you may also prepend
406 additional directories to the search path with AddCatalogLookupPathPrefix().
408 All loaded catalogs will be used for message lookup by GetString() for
411 This overload takes two additional arguments, @a msgIdLanguage and @a msgIdCharset.
414 The catalog domain to add.
417 Specifies the language of "msgid" strings in source code
418 (i.e. arguments to GetString(), wxGetTranslation() and the _() macro).
419 It is used if AddCatalog() cannot find any catalog for current language:
420 if the language is same as source code language, then strings from source
421 code are used instead.
424 Lets you specify the charset used for msgids in sources
425 in case they use 8-bit characters (e.g. German or French strings).
426 This argument has no effect in Unicode build, because literals in sources are
427 Unicode strings; you have to use compiler-specific method of setting the right
428 charset when compiling with Unicode.
431 @true if catalog was successfully loaded, @false otherwise (which might
432 mean that the catalog is not found or that it isn't in the correct format).
434 bool AddCatalog(const wxString
& domain
, wxLanguage msgIdLanguage
,
435 const wxString
& msgIdCharset
);
438 Add a prefix to the catalog lookup path: the message catalog files will
439 be looked up under prefix/lang/LC_MESSAGES, prefix/lang and prefix
442 This only applies to subsequent invocations of AddCatalog().
444 static void AddCatalogLookupPathPrefix(const wxString
& prefix
);
447 Adds custom, user-defined language to the database of known languages.
448 This database is used in conjunction with the first form of Init().
450 static void AddLanguage(const wxLanguageInfo
& info
);
453 This function may be used to find the language description structure for the
454 given locale, specified either as a two letter ISO language code (for example,
455 "pt"), a language code followed by the country code ("pt_BR") or a full, human
456 readable, language description ("Portuguese-Brazil").
458 Returns the information for the given language or @NULL if this language
459 is unknown. Note that even if the returned pointer is valid, the caller
460 should @e not delete it.
462 @see GetLanguageInfo()
464 static wxLanguageInfo
* FindLanguageInfo(const wxString
& locale
);
467 Returns the canonical form of current locale name. Canonical form is the
468 one that is used on UNIX systems: it is a two- or five-letter string in xx or
469 xx_YY format, where xx is ISO 639 code of language and YY is ISO 3166 code of
470 the country. Examples are "en", "en_GB", "en_US" or "fr_FR".
471 This form is internally used when looking up message catalogs.
472 Compare GetSysName().
474 wxString
GetCanonicalName() const;
477 Returns the header value for header @a header.
478 The search for @a header is case sensitive. If an @a domain is passed,
479 this domain is searched. Else all domains will be searched until a
480 header has been found.
482 The return value is the value of the header if found. Else this will be empty.
484 wxString
GetHeaderValue(const wxString
& header
,
485 const wxString
& domain
= wxEmptyString
) const;
488 Returns wxLanguage() constant of current language.
490 Note that you can call this function only if you used the form of
491 Init() that takes wxLanguage argument.
493 int GetLanguage() const;
496 Returns a pointer to wxLanguageInfo structure containing information about
497 the given language or @NULL if this language is unknown. Note that even if
498 the returned pointer is valid, the caller should @e not delete it.
500 See AddLanguage() for the wxLanguageInfo description.
501 As with Init(), @c wxLANGUAGE_DEFAULT has the special meaning if passed
502 as an argument to this function and in this case the result of
503 GetSystemLanguage() is used.
505 static wxLanguageInfo
* GetLanguageInfo(int lang
) const;
508 Returns English name of the given language or empty string if this
511 See GetLanguageInfo() for a remark about special meaning of @c wxLANGUAGE_DEFAULT.
513 static wxString
GetLanguageName(int lang
) const;
516 Returns the locale name as passed to the constructor or Init().
518 This is a full, human-readable name, e.g. "English" or "French".
520 const wxString
& GetLocale() const;
523 Returns the current short name for the locale (as given to the constructor or
524 the Init() function).
526 const wxString

529 Retrieves the translation for a string in all loaded domains unless the @a domain
530 parameter is specified (and then only this catalog/domain is searched).
532 Returns original string if translation is not available (in this case an
533 error message is generated the first time a string is not found; use
534 wxLogNull to suppress it).
536 @remarks Domains are searched in the last to first order, i.e. catalogs
537 added later override those added before.
539 virtual const wxString
& GetString(const wxString

540 const wxString

) const;
543 Retrieves the translation for a string in all loaded domains unless the @a domain
544 parameter is specified (and then only this catalog/domain is searched).
546 Returns original string if translation is not available (in this case an
547 error message is generated the first time a string is not found; use
548 wxLogNull to suppress it).
550 This form is used when retrieving translation of string that has different
551 singular and plural form in English or different plural forms in some
553 It takes two extra arguments: @a origString parameter must contain the
554 singular form of the string to be converted.
556 It is also used as the key for the search in the catalog.
557 The @a origString2 parameter is the plural form (in English).
559 The parameter @a n is used to determine the plural form.
560 If no message catalog is found @a origString is returned if 'n == 1',
561 otherwise @a origString2.
563 See GNU gettext manual for additional information on plural forms handling.
564 This method is called by the wxGetTranslation() function and _() macro.
566 @remarks Domains are searched in the last to first order, i.e. catalogs
567 added later override those added before.

581 Returns wxFontEncoding() value or @c wxFONTENCODING_SYSTEM if it
582 couldn't be determined.
584 static wxFontEncoding
GetSystemEncoding() const;
587 Tries to detect the name of the user's default font encoding.
588 This string isn't particularly useful for the application as its form is
589 platform-dependent and so you should probably use GetSystemEncoding() instead.
591 Returns a user-readable string value or an empty string if it couldn't be
594 static wxString

615 wxLanguage identifier of the locale.
616 @c wxLANGUAGE_DEFAULT has special meaning -- wxLocale will use system's
617 default language (see GetSystemLanguage()).
619 Combination of the following:
620 - wxLOCALE_LOAD_DEFAULT: Load the message catalog for the given locale
621 containing the translations of standard wxWidgets messages
623 - wxLOCALE_CONV_ENCODING: Automatically convert message catalogs to
624 platform's default encoding. Note that it will do only basic
625 conversion between well-known pair like iso8859-1 and windows-1252 or
626 iso8859-2 and windows-1250. See @ref overview_nonenglish for
627 detailed description of this behaviour.
628 Note that this flag is meaningless in Unicode build.
630 @return @true on success or @false if the given locale couldn't be set.
632 bool Init(int language
= wxLANGUAGE_DEFAULT

633 int flags
= wxLOCALE_LOAD_DEFAULT

);
637 This form is deprecated, use the other one unless you know what you are doing.
640 The name of the locale. Only used in diagnostic messages.
642 The standard 2 letter locale abbreviation; it is used as the
643 directory prefix when looking for the message catalog files.
645 The parameter for the call to setlocale().
646 Note that it is platform-specific.
648 May be set to @false to prevent loading of the message catalog for the
649 given locale containing the translations of standard wxWidgets messages.
650 This parameter would be rarely used in normal circumstances.
651 @param bConvertEncoding
652 May be set to @true to do automatic conversion of message catalogs to
653 platform's native encoding. Note that it will do only basic conversion
654 between well-known pair like iso8859-1 and windows-1252 or iso8859-2
656 See @ref overview_nonenglish for detailed description of this behaviour.

665 locales is not installed by default. Returns @true if the locale is
667 The argument @a lang is the wxLanguage identifier. To obtain this for a

700 /** @ingroup group_funcmacro_string */
704 This macro is identical to _() but for the plural variant of
707 @return A const wxString.
711 #define wxPLURAL(string, plural, n)
714 This macro doesn't do anything in the program code -- it simply expands to
715 the value of its argument.
717 However it does have a purpose which is to mark the literal strings for the
718 extraction into the message catalog created by @c xgettext program. Usually
719 this is achieved using _() but that macro not only marks the string for
720 extraction but also expands into a wxGetTranslation() call which means that
721 it cannot be used in some situations, notably for static array
724 Here is an example which should make it more clear: suppose that you have a
725 static array of strings containing the weekday names and which have to be
726 translated (note that it is a bad example, really, as wxDateTime already
727 can be used to get the localized week day names already). If you write:
730 static const char * const weekdays[] = { _("Mon"), ..., _("Sun") };
732 // use weekdays[n] as usual
735 The code wouldn't compile because the function calls are forbidden in the
736 array initializer. So instead you should do this:
739 static const char * const weekdays[] = { wxTRANSLATE("Mon"), ...,
740 wxTRANSLATE("Sun") };
742 // use wxGetTranslation(weekdays[n])
745 Note that although the code @b would compile if you simply omit
746 wxTRANSLATE() in the above, it wouldn't work as expected because there
747 would be no translations for the weekday names in the program message
748 catalog and wxGetTranslation() wouldn't find them.
750 @return A const wxChar*.
754 #define wxTRANSLATE(string)
757 This function returns the translation of @a string in the current
758 @c locale(). If the string is not found in any of the loaded message
759 catalogs (see @ref overview_i18n), the original string is returned. In
760 debug build, an error message is logged -- this should help to find the
761 strings which were not yet translated. If @a domain is specified then only
762 that domain/catalog is searched for a matching string. As this function is
763 used very often, an alternative (and also common in Unix world) syntax is
764 provided: the _() macro is defined to do the same thing as
767 This function calls wxLocale::GetString().
769 @note This function is not suitable for literal strings in Unicode builds
770 since the literal strings must be enclosed into _T() or wxT() macro
771 which makes them unrecognised by @c xgettext, and so they are not
772 extracted to the message catalog. Instead, use the _() and wxPLURAL()
773 macro for all literal strings.
775 @see wxGetTranslation(const wxString&, const wxString&, size_t, const wxString&)
779 const wxString
& wxGetTranslation(const wxString

);
783 This is an overloaded version of
784 wxGetTranslation(const wxString&, const wxString&), please see its
785 documentation for general information.
787 This version is used when retrieving translation of string that has
788 different singular and plural forms in English or different plural forms in
789 some other language. Like wxGetTranslation(const wxString&,const wxString&),
790 the @a string parameter must contain the singular form of the string to be
791 converted and is used as the key for the search in the catalog. The
792 @a plural parameter is the plural form (in English). The parameter @a n is
793 used to determine the plural form. If no message catalog is found,
794 @a string is returned if "n == 1", otherwise @a plural is returned.
796 See GNU gettext Manual for additional information on plural forms handling:
797 <http://www.gnu.org/software/gettext/manual/gettext.html#Plural-forms>
798 For a shorter alternative see the wxPLURAL() macro.
800 This function calls wxLocale::GetString().

& wxGetTranslation(const wxString
& string
,
805 const wxString
& plural
, size_t n
,
806 const wxString

809 This macro expands into a call to wxGetTranslation(), so it marks the
810 message for the extraction by @c xgettext just as wxTRANSLATE() does, but
811 also returns the translation of the string for the current locale during
814 Don't confuse this with _T()!
