Trying to insert tr() returned string in Qhash

Ankit1999

I am trying to createv a QHash <QString, QString> type and inserting the following key values

const QHash <QString, QString> ClassName:MyHash = 
{
 {("test"), tr("Test")},
{("test1"), tr("Test1")}
}

when launching the application its crashing when executing the above code.

application its crashing

How does stack trace look like?

@jsulm i am getting an access violation reading location .. in the call stack i see that it has entered the tr() method and crashed internally in some qt core dll

jsulm

@Ankit1999 Please post the stack trace

@Ankit1999 I think this is going to be a problem.

try const char * instead of a tr marked string:

const QHash <QString, const char *> ClassName:MyHash

than mark the string literal for translation:

const QHash <QString, const char *> ClassName:MyHash = 
{
    {("test"), QT_TRANSLATE_NOOP("MyHash", "Test")},
    {("test1"), QT_TRANSLATE_NOOP("MyHash", "Test1")}
}

than send the string literal through the translation unit on read:

QCoreApplication::translate("MyHash", myHash.value("test"));

ClassName:MyHash

This does not even compile so how should it crash?

Please post either the stack trace or a minimal, compilable example.

I would guess it's a global static which gets initialized before Q(Core)Application so tr() will throw an assert. Don't use global statics (esp. not for such stuff where it's obviouslynot needed at all)

@J-Hilk how do i add the translated strings using QT_TRANSLATE_NOOP the translated strings are not present in the hash even when i add the strings in qt linguist.

It is near literally a working example. let me make it one:

int main(int argc, char *argv[])
{

    QApplication app(argc,argv);

    const QHash <QString, const char *> myHash = 
    {
        {("test"), QT_TRANSLATE_NOOP("MyHash", "Test")},
        {("test1"), QT_TRANSLATE_NOOP("MyHash", "Test1")}
    };
    

    qDebug() << QCoreApplication::translate("MyHash", myHash.value("test"));
    qDebug() << QCoreApplication::translate("MyHash", myHash.value("test1"));
    
    QTranslator t;
    qDebug() << "Loading translation" << t.load("bla.ts");
    app.installTranslator(&t);
    
    qDebug() << QCoreApplication::translate("MyHash", myHash.value("test"));
    qDebug() << QCoreApplication::translate("MyHash", myHash.value("test1"));

    return app.exec();
}

@J-Hilk thank you its working
