title: Appending number to QString with arg() , is there better ways?
body: <p>I've been using QString::number () to convert numbers to string for long time , now i'm wondering if there's something better than following:</p>
  
  <pre><code>  int i = 0;
    QString msg = QString ("Loading %1").arg (QString::number (i));
  </code></pre>
  
  <p>How can i spare QString::number () ? i checked document , seems only "%1" is applicable , no other stuff like "%d" could work</p>
