Qt c++ .arg error in string

Question

I have been getting the error: request for member 'arg' in '("Student number:%1 Module Code: %2 Mark: %3")', which is of non-class type 'const char [43]

can't figure out why I'm getting this error

here is the function that produces the error:

void StudentForm::displayForm(){
    QMessageBox box;
    box.setIcon(QMessageBox::Information);
    stuNum = stuEdt->text().toInt();
    mark = markSbx->text().toInt();
    modCode = codeEdt->text();
    QString t = ("Student number:%1 Module Code: %2 Mark: %3").arg(stuNum).arg(modCode).arg(mark);
    box.setText(t);
    box.exec();
}

let me know if I need to put more of the code up etc. Thanks

You're calling arg as if it was a member of the string literal. — Qaz

QString t = tr("Student number:%1 Module Code: %2 Mark: %3").arg(stuNum).arg(modCode).arg(mark);

tr tries to look up a translated version of the string first - it's a good habit for user-visible strings.

QString t = QString("Student number:%1 Module Code: %2 Mark: %3").arg(stuNum).arg(modCode).arg(mark);
