Can't have application menu bar in english on OSX french

nelbok

Hello,

I would like to launch application in a other language than the OSX settings.
So I have followed this documentation: http://doc.qt.io/qt-5/internationalization.html#enabling-translation
It works fine for other langages like Spanish or Chinese.

But when it comes to english, QTranslator::load fail to load the qt english translation file.
So I have my application in english but not the OSX application menu bar.

What I am doing wrong ?

Here the code:

QString lang = "en"; // Or de, es, it, ru, ...
QTranslator *translator = new QTranslator(this);

bool loadOK = translator->load("qt_" + lang, QLibraryInfo::location(QLibraryInfo::TranslationsPath));
bool installOK = false;
if (loadOK)
    installOK = qApp->installTranslator(translator);
else
    translator->deleteLater();

qDebug() << "Qt translations path: " << QLibraryInfo::location(QLibraryInfo::TranslationsPath);
qDebug() << "Translator: " << "qt_" + lang << " - load: " << loadOK << " - install: " << installOK;

/* For en, the result are:
    Qt translations path: "/Users/[username]/Qt/5.5/clang_64/translations"
    Translator: "qt_en" - load: false - install: false
    */

Hi and welcome to devnet,

The menu bar is a special case in OS X. Take a look here, it describes how to handle the menu bar translation.

Hope it helps

Thanks SGaist,

I have tested your link, but it doesn't work. So i tested other things and i found something strange.
With QtWidgets, the application menu bar is translated nice. I don't have the problem.
But with QML, i have the problem.

So i have the problem only with QML. Actually, i have tested on :

Mountain Lion: Qt 5.5.1 and xcode 5.1.1
Mavericks: Qt 5.5.1 and xcode 5.1.1

There are a special thing to do with QML ?

Can you share a minimal sample project on e.g. github that shows that behavior ?

nelbok

Sorry for the wait.

Here two examples :

one with Qt Widgets where all work well : https://github.com/nelbok/SRPTest/tree/master/widgetsMenuBar
one with Qt Quick where i can't have English on OSX French : https://github.com/nelbok/SRPTest/tree/master/quickMenuBar

For the moment, i have a work around. I create a english translation to manually set the correct values.
I have getted the source of translations module with the Qt installer to have the key translations...

Since my system is in english I've tested both applications loading the german translation file and both worked correctly but I have Qt version that is more recent than you.

Can you check again with the 5.6 Beta ?

nelbok

Hello,

After downloaded and installed qt-opensource-mac-x64-clang-5.6.0-beta.dmg.
On my OSX french and for the QML project, it does not work, i have the application menu bar in french and not in english.

Also, when i run the two project, they say that they can't load qt_en in the output log.

Regards,

nelbok

SGaist

Does it also fail if you change qt_en by qt_de ?

nelbok

When i change lang to de, with Qt 5.5.1 or 5.6, it works fine.

SGaist

So it seems that for some reason there's something funky with the english translation going on...

SGaist

I just realized, Qt is already written in english so it's pretty likely that the qt_en.qm file is empty. So if you need english translation of your non-english written application, you have to provide the english translation of your application. Personally, I'd recommend writing your application in english and provide translations for the other languages.

Hello,

That not the problem here.
If i understand correctly, the OSX Application Menu is translated by Qt, not my application.
The problem occurs only with QtQuick and on a OSX no-english.

So why i must do give a translated file created by me for QtQuick and not for QtWidgets ? (And not the translated files qt)
