title: How to properly store objects/pointers into a Qlist
body: <p>I am new to Qt, and I came across this line:</p>
  
  <pre><code>    QList&lt;Class*&gt;* _lstChildren = new QList&lt;Class*&gt;(); 
  </code></pre>
  
  <p>where the class is derived from another class and has various constructors in it. </p>
  
  <p>I am curious: why an extra <code>*</code> is used and what does <code>()</code> at the end means ?</p>
