323 \class QTranslator -

324 \inmodule QtCore -

325 -

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

327 output. -

328 -

329 \ingroup i18n -

330 -

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

332 source language to a target language. QTranslator provides -

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

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

335 -

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

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

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

339 QTranslator: -

340 -

341 \snippet hellotrmain.cpp 0 -

342 -

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

344 application's widgets. -

345 -

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

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

348 applications that work on translator files. -

349 -

350 \section1 Looking up Translations -

351 -

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

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

354 up to three parameters: -

355 -

356 \list -

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

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

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

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

361 \endlist -

362 -

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

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

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

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

367 would be "Anuluj". -

368 -

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

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

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

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

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

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

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

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

377 and enables Qt to distinguish between translations. -

378 -

379 \section1 Using Multiple Translations -

380 -

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

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

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

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

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

386 string is found. -

387 -

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

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

390 translator from the application by passing it to the -

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

392 QCoreApplication::installTranslator(). It will then be the first -

393 translation to be searched for matching strings. -

394 -

395 \sa QCoreApplication::installTranslator(), QCoreApplication::removeTranslator(), -

396 QObject::tr(), QCoreApplication::translate(), {I18N Example}, -

397 {Hello tr() Example}, {Arrow Pad Example}, {Troll Print Example} -

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

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

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

427 otherwise returns \c false. -

428 -

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

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

431 -

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

433 -

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

435 in the following order: -

436 -

437 \list 1 -

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

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

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

441 an empty string) and \a suffix. -

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

443 \li File name stripped further, etc. -

444 \endlist -

445 -

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

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

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

449 readable file from this list: -

450 -

451 \list 1 -

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

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

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

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

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

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

458 \endlist -

459 -

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

461 const QString &, const QString &, const QString &, const QString &) -

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

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

464 necessarily the UI language. -
