331 \class QTranslator -

332 \inmodule QtCore -

333 -

334 \brief The QTranslator class provides internationalization support for text -

335 output. -

336 -

337 \ingroup i18n -

338 -

339 An object of this class contains a set of translations from a -

340 source language to a target language. QTranslator provides -

341 functions to look up translations in a translation file. -

342 Translation files are created using \l{Qt Linguist}. -

343 -

344 The most common use of QTranslator is to: load a translation -

345 file, install it using QCoreApplication::installTranslator(), and use -

346 it via QObject::tr(). Here's an example \c main() function using the -

347 QTranslator: -

348 -

349 \snippet hellotrmain.cpp 0 -

350 -

351 Note that the translator must be created \e before the -

352 application's widgets. -

353 -

354 Most applications will never need to do anything else with this -

355 class. The other functions provided by this class are useful for -

356 applications that work on translator files. -

357 -

358 \section1 Looking up Translations -

359 -

360 It is possible to look up a translation using translate() (as tr() -

361 and QCoreApplication::translate() do). The translate() function takes -

362 up to three parameters: -

363 -

364 \list -

365 \li The \e context - usually the class name for the tr() caller. -

366 \li The \e {source text} - usually the argument to tr(). -

367 \li The \e disambiguation - an optional string that helps disambiguate -

368 different uses of the same text in the same context. -

369 \endlist -

370 -

371 For example, the "Cancel" in a dialog might have "Anuluj" when the -

372 program runs in Polish (in this case the source text would be -

373 "Cancel"). The context would (normally) be the dialog's class -

374 name; there would normally be no comment, and the translated text -

375 would be "Anuluj". -

376 -

377 But it's not always so simple. The Spanish version of a printer -

378 dialog with settings for two-sided printing and binding would -

379 probably require both "Activado" and "Activada" as translations -

380 for "Enabled". In this case the source text would be "Enabled" in -

381 both cases, and the context would be the dialog's class name, but -

382 the two items would have disambiguations such as "two-sided printing" -

383 for one and "binding" for the other. The disambiguation enables the -

384 translator to choose the appropriate gender for the Spanish version, -

385 and enables Qt to distinguish between translations. -

386 -

387 \section1 Using Multiple Translations -

388 -

389 Multiple translation files can be installed in an application. -

390 Translations are searched for in the reverse order in which they were -

391 installed, so the most recently installed translation file is searched -

392 for translations first and the earliest translation file is searched -

393 last. The search stops as soon as a translation containing a matching -

394 string is found. -

395 -

396 This mechanism makes it possible for a specific translation to be -

397 "selected" or given priority over the others; simply uninstall the -

398 translator from the application by passing it to the -

399 QCoreApplication::removeTranslator() function and reinstall it with -

432 Loads \a filename + \a suffix (".qm" if the \a suffix is not -

433 specified), which may be an absolute file name or relative to \a -

434 directory. Returns \c true if the translation is successfully loaded; -

435 otherwise returns \c false. -

436 -

437 If \a directory is not specified, the current directory is used -

438 (i.e., as \l{QDir::}{currentPath()}). -

439 -

440 The previous contents of this translator object are discarded. -

441 -

442 If the file name does not exist, other file names are tried -

443 in the following order: -

444 -

445 \list 1 -

446 \li File name without \a suffix appended. -

447 \li File name with text after a character in \a search_delimiters -

448 stripped ("_." is the default for \a search_delimiters if it is -

449 an empty string) and \a suffix. -

450 \li File name stripped without \a suffix appended. -

451 \li File name stripped further, etc. -

452 \endlist -

453 -

454 For example, an application running in the fr_CA locale -

455 (French-speaking Canada) might call load("foo.fr_ca", -

456 "/opt/foolib"). load() would then try to open the first existing -

457 readable file from this list: -

458 -

459 \list 1 -

460 \li \c /opt/foolib/foo.fr_ca.qm -

461 \li \c /opt/foolib/foo.fr_ca -

462 \li \c /opt/foolib/foo.fr.qm -

463 \li \c /opt/foolib/foo.fr -

464 \li \c /opt/foolib/foo.qm -

465 \li \c /opt/foolib/foo -

466 \endlist -

467 -

468 Usually, it is better to use the QTranslator::load(const QLocale &, -

469 const QString &, const QString &, const QString &, const QString &) -

470 function instead, because it uses \l{QLocale::uiLanguages()} and not simply -

471 the locale name, which refers to the formatting of dates and numbers and not -

472 necessarily the UI language. -
