title: Question about a QList<QStringList> in Qt
body: <p>I'm using Qt 4.5 and im working with a <code>QList&lt;QStringList&gt;</code> which is a list of string list.</p>
  
  <p>Now I want to replace one string inside one stringList but with it seems unusual to type.  I have found the following way of doing it and was wondering if it is ok:</p>
  
  <pre><code>QList &lt;QStringList&gt; pDataList;
  
  pDataList[listIndex].replace(QStringIndex, newString);
  </code></pre>
  
  <p>Now, I'm not worried about the syntax, but I want to know if <code>pDataList</code>'s pointers is adjascent in memory so that it is okay to use <code>[]</code>. Is there another way to do it?</p>
