title: Qt qApp setFont()
body: <p>I am trying to use the setFont() method to set the font for application wide change. I tried the following:</p>
  
  <pre><code>qApp-&gt;setFont();
  </code></pre>
  
  <p>However, setFont() is not a method of qApp. I am not sure how I can go about setting the font for throughout the application. Could anyone please advise on this?</p>
  
  <p>Thanks.</p>
