304 @class wxLocale
305
306 wxLocale class encapsulates all language-dependent settings and is a
307 generalization of the C locale concept.
308
309 In wxWidgets this class manages message catalogs which contain the translations
310 of the strings used to the current language.
311
312 For a list of the supported languages, please see ::wxLanguage enum values.
313 These constants may be used to specify the language in wxLocale::Init and
314 are returned by wxLocale::GetSystemLanguage.
315
316 @beginWxPerlOnly
317 In wxPerl you can't use the '_' function name, so
318 the @c Wx::Locale module can export the @c gettext and
319 @c gettext_noop under any given name.
320
321 @code
322 # this imports gettext ( equivalent to Wx::GetTranslation
323 # and gettext_noop ( a noop )
324 # into your module
325 use Wx::Locale qw(:default);
326
327 # ....
328
329 # use the functions
330 print gettext( "Panic!" );
331
332 button = Wx::Button-new( window, -1, gettext( "Label" ) );
333 @endcode
334
335 If you need to translate a lot of strings, then adding gettext( ) around
336 each one is a long task ( that is why _( ) was introduced ), so just choose
337 a shorter name for gettext:
338
339 @code
340 use Wx::Locale 'gettext' = 't',
341 'gettext_noop' = 'gettext_noop';
342
343 # ...
344
345 # use the functions
346 print t( "Panic!!" );

615 Initializes the wxLocale instance.
616
617 The call of this function has several global side effects which you should
618 understand: first of all, the application locale is changed - note that
619 this will affect many of standard C library functions such as printf()
620 or strftime().
621 Second, this wxLocale object becomes the new current global locale for
622 the application and so all subsequent calls to wxGetTranslation() will
623 try to translate the messages using the message catalogs for this locale.
624
625 @param language
626 ::wxLanguage identifier of the locale.
627 @c wxLANGUAGE_DEFAULT has special meaning -- wxLocale will use system's
628 default language (see GetSystemLanguage()).
629 @param flags
630 Combination of the following:
631 - wxLOCALE_LOAD_DEFAULT: Load the message catalog for the given locale
632 containing the translations of standard wxWidgets messages
633 automatically.
634 - wxLOCALE_CONV_ENCODING: Automatically convert message catalogs to
635 platform's default encoding. Note that it will do only basic
636 conversion between well-known pair like iso8859-1 and windows-1252 or
637 iso8859-2 and windows-1250. See @ref overview_nonenglish for
638 detailed description of this behaviour.
639 Note that this flag is meaningless in Unicode build.

641 @return @true on success or @false if the given locale couldn't be set.

651 The name of the locale. Only used in diagnostic messages.
652 @param short
653 The standard 2 letter locale abbreviation; it is used as the

728 However it does have a purpose which is to mark the literal strings for the
729 extraction into the message catalog created by @c xgettext program. Usually
730 this is achieved using _() but that macro not only marks the string for
731 extraction but also expands into a wxGetTranslation() call which means that
732 it cannot be used in some situations, notably for static array
733 initialization.
734
735 Here is an example which should make it more clear: suppose that you have a
736 static array of strings containing the weekday names and which have to be
737 translated (note that it is a bad example, really, as wxDateTime already
738 can be used to get the localized week day names already). If you write:
739
740 @code
741 static const char * const weekdays[] = { _("Mon"), ..., _("Sun") };
742 ...
743 // use weekdays[n] as usual
744 @endcode
745
746 The code wouldn't compile because the function calls are forbidden in the
747 array initializer. So instead you should do this:
748
749 @code
750 static const char * const weekdays[] = { wxTRANSLATE("Mon"), ...,
751 wxTRANSLATE("Sun") };
752 ...
753 // use wxGetTranslation(weekdays[n])
754 @endcode
755
756 Note that although the code @b would compile if you simply omit
757 wxTRANSLATE() in the above, it wouldn't work as expected because there
758 would be no translations for the weekday names in the program message
759 catalog and wxGetTranslation() wouldn't find them.

799 different singular and plural forms in English or different plural forms in
800 some other language. Like wxGetTranslation(const wxString&,const wxString&),
801 the @a string parameter must contain the singular form of the string to be

803 @a plural parameter is the plural form (in English). The parameter @a n is
804 used to determine the plural form. If no message catalog is found,
