   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 wxWindows 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 \begin{verbatim}
  13   # this imports gettext ( equivalent to Wx::GetTranslation
  14   # and gettext_noop ( a noop )
  15   # into your module
  16   use Wx::Locale qw(:default);
  17
  18   # ....
  19
  20   # use the functions
  21   print gettext( ``Panic!'' );
  22
  23   button = Wx::Button->new( window, -1, gettext( ``Label'' ) );
  24 \end{verbatim}
  25 If you need to translate a lot of strings, then adding gettext( ) around
  26 each one is a long task ( that is why \_( ) was introduced ), so just choose
  27 a shorter name for gettext:
  28 \begin{verbatim}
  29   #
  30   use Wx::Locale 'gettext' => 't',
  31                  'gettext_noop' => 'gettext_noop';
  32
  33   # ...
  34
  35   # use the functions
  36   print t( ``Panic!!'' );
  37
  38   # ...
  39 \end{verbatim}

 311 \membersection{wxLocale::wxLocale}\label{wxlocaledefctor}
 312
 313 \func{}{wxLocale}{\void}
 314
 315 This is the default constructor and it does nothing to initialize the object:
 316 \helpref{Init()}{wxlocaleinit} must be used to do that.
 317
 318 \func{}{wxLocale}{\param{int }{language}, \param{int }{flags =
 319                           wxLOCALE\_LOAD\_DEFAULT | wxLOCALE\_CONV\_ENCODING}}
 320
 321 See \helpref{Init()}{wxlocaleinit} for parameters description.
 322
 323 \func{}{wxLocale}{\param{const char }{*szName}, \param{const char }{*szShort = NULL}, \param{const char }{*szLocale = NULL}, \param{bool }{bLoadDefault = TRUE}, \param{bool }{bConvertEncoding = FALSE}}
 324
 325 See \helpref{Init()}{wxlocaleinit} for parameters description.
 326
 327 The call of this function has several global side effects which you should
 328 understand: first of all, the application locale is changed - note that this
 329 will affect many of standard C library functions such as printf() or strftime().
 330 Second, this wxLocale object becomes the new current global locale for the
 331 application and so all subsequent calls to wxGetTranslation() will try to
 332 translate the messages using the message catalogs for this locale.
 333
 334
 335 \membersection{wxLocale::\destruct{wxLocale}}\label{wxlocaledtor}
 336
 337 \func{}{\destruct{wxLocale}}{\void}
 338
 339 The destructor, like the constructor, also has global side effects: the previously
 340 set locale is restored and so the changes described in
 341 \helpref{Init}{wxlocaleinit} documentation are rolled back.
 342
 343 \membersection{wxLocale::AddCatalog}\label{wxlocaleaddcatalog}
 344
 345 \func{bool}{AddCatalog}{\param{const char }{*szDomain}}
 346
 347 Add a catalog for use with the current locale: it is searched for in standard
 348 places (current directory first, then the system one), but you may also prepend
 349 additional directories to the search path with
 350 \helpref{AddCatalogLookupPathPrefix()}{wxlocaleaddcataloglookuppathprefix}.
 351
 352 All loaded catalogs will be used for message lookup by GetString() for the
 353 current locale.
 354
 355 Returns TRUE if catalog was successfully loaded, FALSE otherwise (which might
 356 mean that the catalog is not found or that it isn't in the correct format).
 357
 358 \membersection{wxLocale::AddCatalogLookupPathPrefix}\label{wxlocaleaddcataloglookuppathprefix}
 359
 360 \func{void}{AddCatalogLookupPathPrefix}{\param{const wxString\& }{prefix}}
 361
 362 Add a prefix to the catalog lookup path: the message catalog files will be
 363 looked up under prefix/<lang>/LC\_MESSAGES, prefix/LC\_MESSAGES and prefix
 364 (in this order).
 365
 366 This only applies to subsequent invocations of AddCatalog()!
 367
 368 \membersection{wxLocale::AddLanguage}\label{wxlocaleaddlanguage}
 369
 370 \func{static void}{AddLanguage}{\param{const wxLanguageInfo\& }{info}}
 371
 372 Adds custom, user-defined language to the database of known languages. This
 373 database is used in conjuction with the first form of
 374 \helpref{Init}{wxlocaleinit}.
 375
 376 wxLanguageInfo is defined as follows:
 377
 378 \begin{verbatim}
 379 struct WXDLLEXPORT wxLanguageInfo
 380 {
 381     int Language;                   // wxLanguage id
 382     wxString CanonicalName;         // Canonical name, e.g. fr_FR
 383 #ifdef __WIN32__
 384     wxUint32 WinLang, WinSublang;   // Win32 language identifiers
 385                                     // (LANG_xxxx, SUBLANG_xxxx)
 386 #endif
 387     wxString Description;           // human-readable name of the language
 388 };
 389 \end{verbatim}
 390
 391
 392 {\it Language} should be greater than wxLANGUAGE\_USER\_DEFINED.

 397
 398 \membersection{wxLocale::GetCanonicalName}\label{wxlocalegetcanonicalname}
 399
 400 \constfunc{wxString}{GetSysName}{\void}
 401
 402 Returns the canonical form of current locale name. Canonical form is the
 403 one that is used on UNIX systems: it is a two- or five-letter string in xx or
 404 xx\_YY format, where xx is ISO 639 code of language and YY is ISO 3166 code of
 405 the country. Examples are "en", "en\_GB", "en\_US" or "fr\_FR".
 406
 407 This form is internally used when looking up message catalogs.
 408
 409 Compare \helpref{GetSysName}{wxlocalegetsysname}.
 410
 411
 412
 413 \membersection{wxLocale::GetLanguage}\label{wxlocalegetlanguage}
 414
 415 \constfunc{int}{GetLanguage}{\void}
 416
 417 Returns \helpref{wxLanguage}{wxlanguage} constant of current language.
 418 Note that you can call this function only if you used the form of
 419 \helpref{Init}{wxlocaleinit} that takes wxLanguage argument.
 420
 421
 422 \membersection{wxLocale::GetLocale}\label{wxlocalegetlocale}
 423
 424 \constfunc{const char*}{GetLocale}{\void}
 425
 426 Returns the locale name as passed to the constructor or
 427 \helpref{Init()}{wxlocaleinit}. This is full, human-readable name,
 428 e.g. "English" or "French".
 429
 430
 431 \membersection{wxLocale::GetName}\label{wxlocalegetname}
 432
 433 \constfunc{const wxString\&}{GetName}{\void}
 434
 435 Returns the current short name for the locale (as given to the constructor or
 436 the Init() function).
 437
 438 \membersection{wxLocale::GetString}\label{wxlocalegetstring}
 439
 440 \constfunc{const char*}{GetString}{\param{const char }{*szOrigString}, \param{const char }{*szDomain = NULL}}
 441
 442 Retrieves the translation for a string in all loaded domains unless the szDomain
 443 parameter is specified (and then only this catalog/domain is searched).
 444
 445 Returns original string if translation is not available
 446 (in this case an error message is generated the first time
 447 a string is not found; use \helpref{wxLogNull}{wxlogoverview} to suppress it).
 448
 449 \wxheading{Remarks}
 450
 451 Domains are searched in the last to first order, i.e. catalogs
 452 added later override those added before.
 453
 454 \membersection{wxLocale::GetSysName}\label{wxlocalegetsysname}
 455
 456 \constfunc{wxString}{GetSysName}{\void}
 457
 458 Returns current platform-specific locale name as passed to setlocale().
 459
 460 Compare \helpref{GetCanonicalName}{wxlocalegetcanonicalname}.
 461
 462
 463 \membersection{wxLocale::GetSystemEncoding}\label{wxlocalegetsystemencoding}
 464
 465 \constfunc{static wxFontEncoding}{GetSystemEncoding}{\void}
 466
 467 Tries to detect the user's default font encoding.
 468 Returns \helpref{wxFontEncoding}{wxfont} value or
 469 {\bf wxFONTENCODING\_SYSTEM} if it couldn't be determined.
 470
 471 \membersection{wxLocale::GetSystemEncodingName}\label{wxlocalegetsystemencodingname}
 472
 473 \constfunc{static wxString}{GetSystemEncodingName}{\void}
 474
 475 Tries to detect the name of the user's default font encoding. This string isn't
 476 particularly useful for the application as its form is platform-dependent and
 477 so you should probably use
 478 \helpref{GetSystemEncoding}{wxlocalegetsystemencoding} instead.
 479
 480 Returns a user-readable string value or an empty string if it couldn't be
 481 determined.
 482
 483 \membersection{wxLocale::GetSystemLanguage}\label{wxlocalegetsystemlanguage}
 484
 485 \constfunc{static int}{GetSystemLanguage}{\void}
 486
 487 Tries to detect the user's default language setting.
 488 Returns \helpref{wxLanguage}{wxlanguage} value or
 489  {\bf wxLANGUAGE\_UNKNOWN} if the language-guessing algorithm failed.

 499
 500 The second form is deprecated, use the first one unless you know what you are
 501 doing.

 503
 504 \wxheading{Parameters}
 505
 506 \docparam{language}{\helpref{wxLanguage}{wxlanguage} identifier of the locale.
 507 wxLANGUAGE\_DEFAULT has special meaning -- wxLocale will use system's default
 508 language (see \helpref{GetSystemLanguage}{wxlocalegetsystemlanguage}).}

 521 }
 522
 523 \docparam{szName}{The name of the locale. Only used in diagnostic messages.}

 530
 531 \docparam{bLoadDefault}{May be set to FALSE to prevent loading of the message catalog

 543 The call of this function has several global side effects which you should
 544 understand: first of all, the application locale is changed - note that this
 545 will affect many of standard C library functions such as printf() or strftime().
 546 Second, this wxLocale object becomes the new current global locale for the
 547 application and so all subsequent calls to wxGetTranslation() will try to
 548 translate the messages using the message catalogs for this locale.

 554 \constfunc{bool}{IsLoaded}{\param{const char* }{domain}}
 555
 556 Check if the given catalog is loaded, and returns TRUE if it is.
 557

 559 normally corresponds to 'domain' which is more or less the application name.
