title: Should I use Qt signal/slot mechanisms over traditional callbacks?
body: <p>A senior developer in my team used traditional <a href="http://www.newty.de/fpt/callback.html" rel="noreferrer">C-style callbacks</a> in our Qt application instead of using Qt signal/slot mechanisms.  </p>
  
  <p>My first reflex would be to replace his code and use Qt signal/slot instead.</p>
  
  <p>Is there any good reasons to use callbacks in a Qt application/library?</p>
  
  <p>Thanks.</p>
