QTranslator and qtbase_en.qm

Mark58

Hi,

In my main.cpp I implemented the QTranslator like this:

QString translationsPath(QLibraryInfo::location(QLibraryInfo::TranslationsPath));
QLocale locale(QLocale::English, QLocale::UnitedStates);

QTranslator qtBaseTranslator;
    qtBaseTranslator.load(locale, "qtbase", "_", translationsPath);
        qDebug() << "load2:"<< a.installTranslator(&qtBaseTranslator);

The Debug intormation is:
load1 true
load2: false

The file "C:\Qt\5.13.0\mingw73_32\translations\qtbase_en.qm" exists, but the translator does not work.

Now I found out that the size of my "qtbase_en.qm"-file is only 1 KB; other qtbase_xy.qm-files have a size of 150KB to 200KB.

Where can I get a working "qtbase_en.qm"-file?
Thanks.

When you want an english - english translation you have to do it by yourself I would guess.

Thanks, but that's not the problem. Maybe I tried to simplify my problem too much.

The "qtbase_...qm" file should translate e.g. the buttonbox-Button.
I start my app in Spanish. Therefore I have a QTranslator in my main.cpp like this:

QString translationsPath(QLibraryInfo::location(QLibraryInfo::TranslationsPath));
    QLocale locale(QLocale::Spanish, QLocale::Spain);
    QTranslator qtBaseTranslator;
    qDebug() << "path" << qtBaseTranslator.load(locale, "qtbase", "_", translationsPath);
    qDebug() << "load:"<< a.installTranslator(&qtBaseTranslator);

This works fine and the buttonbox-Button is shown in spanish:

In my mainwindow.cpp I have three slots to change the language into german, french or english.
Generally, this works fine - e.g. for french:

void MainWindow::on_pushButton_3_clicked()
{
    //Francais

    QString translationsPath(QLibraryInfo::location(QLibraryInfo::TranslationsPath));
    QLocale locale(QLocale::French, QLocale::France);

    QTranslator *qtBaseTranslator = new QTranslator(this);
    qDebug() << "path francais:" << qtBaseTranslator->load(locale, "qtbase", "_", translationsPath);
    qDebug() << "load francais:"<< qApp->installTranslator(qtBaseTranslator);
}

This works fine as well. The Debug-output is:
path francais: true
load francais: true

The buttonbox-Button - language changes to french:

My problem is, that the translation to English does not work:

void MainWindow::on_pushButton_4_clicked()
{
    //English
    
    QString translationsPath(QLibraryInfo::location(QLibraryInfo::TranslationsPath));
    QLocale locale(QLocale::English, QLocale::UnitedKingdom);

    QTranslator *qtBaseTranslator = new QTranslator(this);
    qDebug() << "trans" <<translationsPath;
    qDebug() << "path English:" << qtBaseTranslator->load(locale, "qtbase", "_", translationsPath);
    qDebug() << "translator empty?:" << qtBaseTranslator->isEmpty();
    qDebug() << "load English:"<< qApp->installTranslator(qtBaseTranslator);
}

The Debug - Output is:
trans "C:/Qt/5.13.0/mingw73_32/translations"
path English: true
translator empty?: true
load English: false

As a consequence, the language changes back to Spanish, because this is the language in the main.cpp.

In the directory "C:/Qt/5.13.0/mingw73_32/translations" I have a qtbase_en.qm with a size of 1KB only.

Any help would be fine. Thanks.

If yoiu don't need a translator anymore, remove it.

@Christian-Ehrlicher Hello, I recently encountered this problem and would like to ask if you have a solution. I found that manually translating the generated qt_en.ts and translating it into qt_en.qm can solve the problem, but it is a bit time-consuming. It seems that Qt's mechanism is that when there is no translation text, it will use your system's local language (Spanish).

@bokun the OP's problem was most likely a lifetime issue of the stack allocated QTranslator, if I had to guess
