QMessageBox error

[Salazaar]

Hi. I've got a problem. I have a piece of code:

int ret = QMessageBox::Information(this, tr("Speed Units Converter"),
                   tr("You can't convert value to the same unit"),
                   QMessageBox::Ok | QMessageBox::Default);
                   if (ret == QMessageBox::Ok)
                   {
                   return false;
                   }

int ret = QMessageBox::Information(this, tr("Speed Units Converter"),
                   tr("You can't convert value to the same unit"),
                   QMessageBox::Ok | QMessageBox::Default);
                   if (ret == QMessageBox::Ok)
                   {
                   return false;
                   }

To copy to clipboard, switch view to plain text mode 

And I reach error that Information cannot be used as a function
