title: Qt include files
body: <p>I got into a discussion with somebody that tells me that it's not good to do what Qt does with include files because i adopted the same strategy in my code.</p>
  
  <p>Let's use QApplication as an example, when you want to include QApplication then you should do:</p>
  
  <pre><code>#include &lt;QApplication&gt;
  </code></pre>
  
  <p>QApplication is a file without extension that contains:</p>
  
  <pre><code>#include "qapplication.h"
  </code></pre>
  
  <p>The only disadvantage is see is that it creates more files in the project. Besides that i think it only has advantages.</p>
  
  <p>So my question is, why is this a good or a bad idea?</p>
