title: QComboBox Get The Varient When "currentIndexChanged(int)" Emitted
body: <p>I am having difficulty finding documentation on this or an example.</p>
  
  <p>Could someone concretely show me how to access the QVariant of the currently selected index in a QComboBox</p>
  
  <pre><code> QComboBox * combo = new QComboBox();
   combo-&gt;addItem("Bla1", QVariant(1));
   combo-&gt;addItem("Bla2", QVariant(2));
   combo-&gt;addItem("Bla3", QVariant(3));
   combo-&gt;addItem("Bla4", QVariant(4));
   connect(combo, SIGNAL(currentIndexChanged(int)), this, slot(HANDLEITMAN(int))
  </code></pre>
  
  <p>And of course else where in the source</p>
  
  <pre><code> void TheCooler::HANDLEITMAN(int index)
   {
        //What do I do with index?
        //sender()?
   }
  </code></pre>
