   1 \section{\class{wxLocale}}\label{wxlocale}
   2
   3 wxLocale class encapsulates all language-dependent settings and is a
   4 generalization of the C locale concept.
   5
   6 In wxWidgets this class manages message catalogs which contain the translations
   7 of the strings used to the current language.
   8
   9 \perlnote{In wxPerl you can't use the '\_' function name, so
  10 the {\tt Wx::Locale} module can export the {\tt gettext} and
  11 {\tt gettext\_noop} under any given name.
  12
  13 \begin{verbatim}
  14   # this imports gettext ( equivalent to Wx::GetTranslation
  15   # and gettext_noop ( a noop )
  16   # into your module
  17   use Wx::Locale qw(:default);
  18
  19   # ....
  20
  21   # use the functions
  22   print gettext( ``Panic!'' );
  23
  24   button = Wx::Button->new( window, -1, gettext( ``Label'' ) );
  25 \end{verbatim}
  26
  27 If you need to translate a lot of strings, then adding gettext( ) around
  28 each one is a long task ( that is why \_( ) was introduced ), so just choose
  29 a shorter name for gettext:
  30
  31 \begin{verbatim}
  32   #
  33   use Wx::Locale 'gettext' => 't',
  34                  'gettext_noop' => 'gettext_noop';
  35
  36   # ...
  37
  38   # use the functions
  39   print t( ``Panic!!'' );
  40
  41   # ...
  42 \end{verbatim}

 315 \membersection{wxLocale::wxLocale}\label{wxlocaledefctor}
 316
 317 \func{}{wxLocale}{\void}
 318
 319 This is the default constructor and it does nothing to initialize the object:
 320 \helpref{Init()}{wxlocaleinit} must be used to do that.
 321
 322 \func{}{wxLocale}{\param{int }{language}, \param{int }{flags =
 323                           wxLOCALE\_LOAD\_DEFAULT | wxLOCALE\_CONV\_ENCODING}}
 324
 325 See \helpref{Init()}{wxlocaleinit} for parameters description.
 326
 327 \func{}{wxLocale}{\param{const char }{*szName}, \param{const char }{*szShort = NULL}, \param{const char }{*szLocale = NULL}, \param{bool }{bLoadDefault = true}, \param{bool }{bConvertEncoding = false}}
 328
 329 See \helpref{Init()}{wxlocaleinit} for parameters description.
 330
 331 The call of this function has several global side effects which you should
 332 understand: first of all, the application locale is changed - note that this
 333 will affect many of standard C library functions such as printf() or strftime().
 334 Second, this wxLocale object becomes the new current global locale for the
 335 application and so all subsequent calls to wxGetTranslation() will try to
 336 translate the messages using the message catalogs for this locale.
 337
 338
 339 \membersection{wxLocale::\destruct{wxLocale}}\label{wxlocaledtor}
 340
 341 \func{}{\destruct{wxLocale}}{\void}
 342
 343 The destructor, like the constructor, also has global side effects: the previously
 344 set locale is restored and so the changes described in
 345 \helpref{Init}{wxlocaleinit} documentation are rolled back.
 346
 347 \membersection{wxLocale::AddCatalog}\label{wxlocaleaddcatalog}
 348
 349 \func{bool}{AddCatalog}{\param{const char }{*szDomain}}
 350
 351 Add a catalog for use with the current locale: it is searched for in standard
 352 places (current directory first, then the system one), but you may also prepend
 353 additional directories to the search path with
 354 \helpref{AddCatalogLookupPathPrefix()}{wxlocaleaddcataloglookuppathprefix}.
 355
 356 All loaded catalogs will be used for message lookup by GetString() for the
 357 current locale.
 358
 359 Returns true if catalog was successfully loaded, false otherwise (which might
 360 mean that the catalog is not found or that it isn't in the correct format).
 361
 362 \membersection{wxLocale::AddCatalogLookupPathPrefix}\label{wxlocaleaddcataloglookuppathprefix}
 363
 364 \func{void}{AddCatalogLookupPathPrefix}{\param{const wxString\& }{prefix}}
 365
 366 Add a prefix to the catalog lookup path: the message catalog files will be
 367 looked up under prefix/<lang>/LC\_MESSAGES, prefix/LC\_MESSAGES and prefix
 368 (in this order).
 369
 370 This only applies to subsequent invocations of AddCatalog()!
 371
 372 \membersection{wxLocale::AddLanguage}\label{wxlocaleaddlanguage}
 373
 374 \func{static void}{AddLanguage}{\param{const wxLanguageInfo\& }{info}}
 375
 376 Adds custom, user-defined language to the database of known languages. This
 377 database is used in conjunction with the first form of
 378 \helpref{Init}{wxlocaleinit}.
 379
 380 wxLanguageInfo is defined as follows:
 381
 382 \begin{verbatim}
 383 struct WXDLLEXPORT wxLanguageInfo
 384 {
 385     int Language;                   // wxLanguage id
 386     wxString CanonicalName;         // Canonical name, e.g. fr_FR
 387 #ifdef __WIN32__
 388     wxUint32 WinLang, WinSublang;   // Win32 language identifiers
 389                                     // (LANG_xxxx, SUBLANG_xxxx)
 390 #endif
 391     wxString Description;           // human-readable name of the language
 392 };
 393 \end{verbatim}
 394
 395
 396 {\it Language} should be greater than wxLANGUAGE\_USER\_DEFINED.

 399 Wx::LanguageInfo->new( language, canonicalName, WinLang, WinSubLang, Description )}
 400
 401 \membersection{wxLocale::FindLanguageInfo}{wxlocalefindlanguageinfo}
 402
 403 \constfunc{static wxLanguageInfo *}{FindLanguageInfo}{\param{const wxString\& }{locale}}
 404
 405 This function may be used to find the language description structure for the
 406 given locale, specified either as a two letter ISO language code (for example,
 407 "pt"), a language code followed by the country code ("pt\_BR") or a full, human
 408 readable, language description ("Portuguese-Brazil").
 409
 410 Returns the information for the given language or {\tt NULL} if this language
 411 is unknown. Note that even if the returned pointer is valid, the caller should
 412 {\it not} delete it.

 418 \membersection{wxLocale::GetCanonicalName}\label{wxlocalegetcanonicalname}
 419
 420 \constfunc{wxString}{GetSysName}{\void}
 421
 422 Returns the canonical form of current locale name. Canonical form is the
 423 one that is used on UNIX systems: it is a two- or five-letter string in xx or
 424 xx\_YY format, where xx is ISO 639 code of language and YY is ISO 3166 code of
 425 the country. Examples are "en", "en\_GB", "en\_US" or "fr\_FR".
 426
 427 This form is internally used when looking up message catalogs.
 428
 429 Compare \helpref{GetSysName}{wxlocalegetsysname}.
 430
 431
 432
 433 \membersection{wxLocale::GetLanguage}\label{wxlocalegetlanguage}
 434
 435 \constfunc{int}{GetLanguage}{\void}
 436
 437 Returns \helpref{wxLanguage}{wxlanguage} constant of current language.
 438 Note that you can call this function only if you used the form of
 439 \helpref{Init}{wxlocaleinit} that takes wxLanguage argument.
 440
 441 \membersection{wxLocale::GetLanguageInfo}\label{wxlocalegetlanguageinfo}
 442
 443 \constfunc{static wxLanguageInfo *}{GetLanguageInfo}{\param{int }{lang}}
 444
 445 Returns a pointer to wxLanguageInfo structure containing information about the
 446 given language or {\tt NULL} if this language is unknown. Note that even if the
 447 returned pointer is valid, the caller should {\it not} delete it.
 448
 449 See \helpref{AddLanguage}{wxlocaleaddlanguage} for the wxLanguageInfo
 450 description.
 451
 452 \membersection{wxLocale::GetLanguageName}\label{wxlocalegetlanguagename}
 453
 454 \constfunc{static wxString}{GetLanguageName}{\param{int }{lang}}

 457 language is unknown.
 458
 459
 460 \membersection{wxLocale::GetLocale}\label{wxlocalegetlocale}
 461
 462 \constfunc{const char*}{GetLocale}{\void}
 463
 464 Returns the locale name as passed to the constructor or
 465 \helpref{Init()}{wxlocaleinit}. This is full, human-readable name,
 466 e.g. "English" or "French".
 467
 468
 469 \membersection{wxLocale::GetName}\label{wxlocalegetname}
 470
 471 \constfunc{const wxString\&}{GetName}{\void}
 472
 473 Returns the current short name for the locale (as given to the constructor or
 474 the Init() function).
 475
 476 \membersection{wxLocale::GetString}\label{wxlocalegetstring}
 477
 478 \constfunc{const char*}{GetString}{\param{const char }{*szOrigString}, \param{const char }{*szDomain = NULL}}
 479
 480 \constfunc{const char*}{GetString}{\param{const char }{*szOrigString}, \param{const char }{*szOrigString2}, \param{size\_t }{n}, \param{const char }{*szDomain = NULL}}
 481
 482 Retrieves the translation for a string in all loaded domains unless the szDomain
 483 parameter is specified (and then only this catalog/domain is searched).
 484
 485 Returns original string if translation is not available
 486 (in this case an error message is generated the first time
 487 a string is not found; use \helpref{wxLogNull}{wxlogoverview} to suppress it).
 488
 489 The second form is used when retrieving translation of string that has
 490 different singular and plural form in English or different plural forms in some
 491 other language. It takes two extra arguments: \arg{szOrigString}
 492 parameter must contain the singular form of the string to be converted.
 493 It is also used as the key for the search in the catalog.
 494 The \arg{szOrigString2} parameter is the plural form (in English).
 495 The parameter \arg{n} is used to determine the plural form.  If no
 496 message catalog is found \arg{szOrigString} is returned if `n == 1',
 497 otherwise \arg{szOrigString2}.
 498 See \urlref{GNU gettext manual}{http://www.gnu.org/manual/gettext/html\_chapter/gettext\_10.html\#SEC150} for additional information on plural forms handling.
 499
 500 \wxheading{Remarks}
 501
 502 Domains are searched in the last to first order, i.e. catalogs
 503 added later override those added before.
 504
 505 \membersection{wxLocale::GetSysName}\label{wxlocalegetsysname}
 506
 507 \constfunc{wxString}{GetSysName}{\void}
 508
 509 Returns current platform-specific locale name as passed to setlocale().
 510
 511 Compare \helpref{GetCanonicalName}{wxlocalegetcanonicalname}.
 512
 513
 514 \membersection{wxLocale::GetSystemEncoding}\label{wxlocalegetsystemencoding}
 515
 516 \constfunc{static wxFontEncoding}{GetSystemEncoding}{\void}
 517
 518 Tries to detect the user's default font encoding.
 519 Returns \helpref{wxFontEncoding}{wxfont} value or
 520 {\bf wxFONTENCODING\_SYSTEM} if it couldn't be determined.
 521
 522 \membersection{wxLocale::GetSystemEncodingName}\label{wxlocalegetsystemencodingname}
 523
 524 \constfunc{static wxString}{GetSystemEncodingName}{\void}
 525
 526 Tries to detect the name of the user's default font encoding. This string isn't
 527 particularly useful for the application as its form is platform-dependent and
 528 so you should probably use
 529 \helpref{GetSystemEncoding}{wxlocalegetsystemencoding} instead.
 530
 531 Returns a user-readable string value or an empty string if it couldn't be
 532 determined.
 533
 534 \membersection{wxLocale::GetSystemLanguage}\label{wxlocalegetsystemlanguage}
 535
 536 \constfunc{static int}{GetSystemLanguage}{\void}
 537
 538 Tries to detect the user's default language setting.
 539 Returns \helpref{wxLanguage}{wxlanguage} value or
 540  {\bf wxLANGUAGE\_UNKNOWN} if the language-guessing algorithm failed.

 556
 557 \docparam{language}{\helpref{wxLanguage}{wxlanguage} identifier of the locale.
 558 wxLANGUAGE\_DEFAULT has special meaning -- wxLocale will use system's default
 559 language (see \helpref{GetSystemLanguage}{wxlocalegetsystemlanguage}).}
 560
 561 \docparam{flags}{Combination of the following:
 562
 563
 564 \begin{twocollist}\itemsep=0pt
 565 \twocolitem{\windowstyle{wxLOCALE\_LOAD\_DEFAULT}}{Load the message catalog
 566 for the given locale containing the translations of standard wxWidgets messages
 567 automatically.}
 568 \twocolitem{\windowstyle{wxLOCALE\_CONV\_ENCODING}}{Automatically convert message
 569 catalogs to platform's default encoding. Note that it will do only basic
 570 conversion between well-known pair like iso8859-1 and windows-1252 or
 571 iso8859-2 and windows-1250. See \helpref{Writing non-English applications}{nonenglishoverview} for detailed
 572 description of this behaviour. Note that this flag is meaningless in Unicode build.}
 573 \end{twocollist}
 574 }
 575
 576 \docparam{szName}{The name of the locale. Only used in diagnostic messages.}
 577
 578 \docparam{szShort}{The standard 2 letter locale abbreviation and is used as the
 579 directory prefix when looking for the message catalog files.}
 580
 581 \docparam{szLocale}{The parameter for the call to setlocale(). Note that it is
 582 platform-specific.}
 583
 584 \docparam{bLoadDefault}{May be set to false to prevent loading of the message catalog
 585 for the given locale containing the translations of standard wxWidgets messages.
 586 This parameter would be rarely used in normal circumstances.}
 587
 588 \docparam{bConvertEncoding}{May be set to true to do automatic conversion of message
 589 catalogs to platform's native encoding. Note that it will do only basic
 590 conversion between well-known pair like iso8859-1 and windows-1252 or
 591 iso8859-2 and windows-1250.
 592 See \helpref{Writing non-English applications}{nonenglishoverview} for detailed
 593 description of this behaviour.}

 596 The call of this function has several global side effects which you should
 597 understand: first of all, the application locale is changed - note that this
 598 will affect many of standard C library functions such as printf() or strftime().
 599 Second, this wxLocale object becomes the new current global locale for the
 600 application and so all subsequent calls to wxGetTranslation() will try to
 601 translate the messages using the message catalogs for this locale.
 602
 603 Returns true on success or false if the given locale couldn't be set.

 606
 607 \constfunc{bool}{IsLoaded}{\param{const char* }{domain}}
 608
 609 Check if the given catalog is loaded, and returns true if it is.
 610
 611 According to GNU gettext tradition, each catalog
 612 normally corresponds to 'domain' which is more or less the application name.

 619
 620 Returns true if the locale could be set successfully.
