title: Setting items in Qt combo box
body: <p>I'm very new to Qt. I'm following this tutorial <a href="http://sector.ynet.sk/qt4-tutorial/my-first-qt-gui-application.html" rel="noreferrer">http://sector.ynet.sk/qt4-tutorial/my-first-qt-gui-application.html</a>. There is a small mistake in this tutorial. Though it adds a combo box entry, text is not set. Can somebody tell me how to initialize the combo box, correctly. </p>
  
  <p>Also, can somebody point out me if there are better tutorials for learning Qt ?</p>
