title: Getting multiple inputs from QInputDialog in Qt
body: <p>I would like to get a set of four values from four input labels in Qt. I would like to use <code>QInputDialog</code> but it contains only one <code>inputbox</code> as a default one. So, how can I add <strong>four labels</strong> and <strong>four line-edits</strong> and get the value from it?</p>
