title: Qt C++ initialize a QStringList class member
body: <p>I have a class member of type <code>QStringList</code>. I had a guess that when this class is instantiated, <code>nex</code> instance get such a <code>QStringLsit</code> with no elements in it.<br>
  I have a function that should fill in this <code>QStringList</code> on user interaction. However, I see with debugger that class member does not exist at function call. What could it be all about? Is there a way to initialize the <code>QListString</code> that I may be missing here?</p>
