title: Qt QDesktopServices::openUrl - launch browser with post values
body: <p>I'm trying to write a simple application that will launch a browser and send it to a <code>URL</code> based on a user's input.</p>
  
  <pre><code>QDesktopServices::openUrl(QUrl(url));
  </code></pre>
  
  <p>However, I'd like to pass variables along with whatever <code>URL</code> they submit using <code>POST</code>.
  For <code>GET</code>, all I'd need to do is simply embed the values into the <code>URL</code> string, but how would I go about adding <code>POST</code> variables?.</p>
  
  <p>Thanks.</p>
