Problem when translating my app

Hi all !

I'm trying to translate my application. All is ok with the files which come from .ui . But with aller QMessageBox (just an exemple), I have a problem :

here's the main.cpp :

Code:

---

int main(int argc, char **argv)
{
    ...
    else if(argc == 1)
    {
        // the translation is loaded in the contructor of ui_murefImpl (see below this code)
        ui_murefImpl window(0, &app);
        window.show();
 
        // I'm doing this because I saw this in the ui.h file (and tr() && QApplication::translate() are too ineffective
        QPushButton hello(QApplication::translate("MainWindow", "Music", 0, QApplication::UnicodeUTF8));
        hello.resize(100, 30);
        hello.show();
 
        return app.exec();
    }
    ....
}

---

Code:

---

ui_murefImpl::ui_murefImpl(QWidget *parent, QApplication *myApp) : QMainWindow(parent)
{
    configure(myApp);
}
 
void ui_murefImpl::configure(QApplication *myApp)
{
    // all that is correct because the ui is translated !
    QTranslator translator;
    QString locale = QLocale::system().name();
    translator.load(QString("MuRef_") + locale);
    myApp->installTranslator(&translator);
    ...
    ui.setupUi(this);
    ...
}

---

The problem is that (of course) the text in the button is not translated (but I do correctly all the other manipulations : lupdate, qtlinguist (made changements, saved), lrelease and launching the program).


Thanks for reading ;) !

P.S.: I'm doing tests on a "hello button" because I don't want to recompile each time the whole app. But if it work on a QPushButton, it will still work with a QMessageBox...

What makes you think so?

Can you see that button text when you open .ts file in Qt Linguist?

For the best reason : I tested before asking ;) !

For sure I can (if not, how could I translate it since I use Qt Linguist ?).

Note : it appears in the context "MainWindow" and the source text panel is "Music" and I 'translated' it to "No music".

Edit :
this is a MINIMAL .pro file (I just want to translate the button, that will be a nice beginning :p !)

Code:

---

TEMPLATE = app
TARGET += 
DEPENDPATH += .
INCLUDEPATH += .
 
# Input
HEADERS +=
FORMS += muref.ui
SOURCES += main.cpp
TRANSLATIONS += MuRef_fr.ts

---

when I try with tr() I got this error :

Quote:

---

main.cpp:23: error: `tr' undeclared (first use this function)
main.cpp:23: error: (Each undeclared identifier is reported only once for each function it appears in.)
:: === Build finished: 2 errors, 0 warnings ===

And why it isn't effective?

Are you sure that your application loads the newest .qm file?

when I try with tr() I got this error :

---

tr() is a static method of QObject class.

Code:

---

QPushButton hello( QObject::tr( "Music" ) );

Because it doesn't work in my case ! (and of course I have a problem because that's very useful functions... there's no doubt about this)

How can I be ? There's only one .qm file and thus if it load the ui translation, it must load the others... (I don't really know about this).

Correct ! I understood that while I was reading the chapter 15 (internationalisation) of the Qt 3 online book ;) !

edit : of course, I deleted the .ts and the .qm and made new ones to be sure that is a "proper" translation but that didn't change anything to my problem ! Do you need more source code or screenshots ?

Ah, OK. "too ineffective" == "doesn't work in my case"

Then delete that file, start your application and check if no translation was loaded, create a new .qm file and check your application again.

Yes I'm sorry English isn't my native language thus sometimes I may use some incorrect way of putting things togheter but I try to be at least readable ;).

Ok I'll try that tomorrow ! (it's midnight here :p (Beligum))

Already thanks for trying to help me ;) that's not the first time :p !

I've just took another look on your configure() method. You create the translator on the stack, so it gets destroyed when configure() returns.

It should be:

Code:

---

void ui_murefImpl::configure(QApplication *myApp)
{
    QTranslator *translator= new QTranslator();
    ...
    translator->load(QString("MuRef_") + locale);
    myApp->installTranslator( translator );
    ...
}

Yes yes yes !!! That works :D thanks a lot !
