qml对话框上的翻译按钮

Question

I am using QML MessageDialog with a Cancel and a Yes button. My phone is set to german, but the Cancel and Yes button are not translated.

I am following the qt documentation here and added this to my main:

QTranslator qtTranslator;
qtTranslator.load("qt_" + QLocale::system().name(),
        QLibraryInfo::location(QLibraryInfo::TranslationsPath));
app.installTranslator(&qtTranslator);

It does not work. This code:

qDebug() << QLibraryInfo::location(QLibraryInfo::TranslationsPath);
qDebug() << qtTranslator.isEmpty();

Tells me:

1. The translation path is: /work/build/______________________________PADDING______________________________/translations

2. The qtTranslator object is empty.

I also load a translator for my own strings, and that works.

So I do I properly initialize translation of Qt internal stings on android?

Answer 1

If you want translate your application you should distrubute qt translation files with it. For android simple copy translation files to assets folder. Then set this path for qtTranslator .

You can do this with qmake. Just put this to your .pro file:

android {
    ANDROID_PACKAGE_SOURCE_DIR = $$PWD/android
    TRDESTDIR = $$system_path($$PWD/android/assets/translations)
    QMAKE_POST_LINK = $$QMAKE_COPY $$shell_path($$[QT_INSTALL_TRANSLATIONS]/qt*_ru.qm) $$TRDESTDIR
}

Of course you should change ANDROID_PACKAGE_SOURCE_DIR and TRDESTDIR to your actual location if it differs. Also you should change qt*_ru.qm to your language.

Then you could load translation like:

qtTranslator.load("qt_ru","assets:/translations")
