QString::arg: Argument missing

[BalaQT]

hi,
I'm using linguist to translate the following, (environment: ubuntu,qt4.7)

MainWindow::MainWindow(QWidget *parent) :
    QMainWindow(parent),
    ui(new Ui::MainWindow)
{
    QTranslator translator;
    QString txt1="text";
    translator.load("testLang");
    qApp->installTranslator(&translator);
    ui->setupUi(this);
    l=new QLabel(this);
    l->setText(tr("file %1").arg(txt1));
}

MainWindow::MainWindow(QWidget *parent) :
    QMainWindow(parent),
    ui(new Ui::MainWindow)
{
    QTranslator translator;
    QString txt1="text";
    translator.load("testLang");
    qApp->installTranslator(&translator);
    ui->setupUi(this);
    l=new QLabel(this);
    l->setText(tr("file %1").arg(txt1));
}

To copy to clipboard, switch view to plain text mode 

But I'm getting the following warning:
QString::arg: Argument missing: test translatedText, text
(translatedText: The text translated in the target language.)
what's the possible cause , how can i get rid of this?
Thanks in advance.

The translation probably doesn't contain "%1".

hi master,
Thanks for 'your reply' (thought of using 'ur reply' afraid of your infractions ).

The translation probably doesn't contain "%1".

In translation I'm having 'file translatedText' for the code tr(file %1).arg(txt1).
My assumption is the translatedText will be placed in the %1. Is it right?

Note: I'm getting the output correctly, But I want to remove the warning.
May be a simple thing, which I'm missing completely.

Thanks,
Bala

No. %1 is for QString::arg() to work. And it needs to be present in the translated string as well.
