title: QScrollArea widget is not expanding with a Flowlayout
body: <p>I have a ui with a <code>QScrollArea</code> Widget. The <code>QScrollArea</code> uses a <a href="http://doc.qt.digia.com/4.7/layouts-flowlayout.html" rel="noreferrer">Flowlayout</a>. My problem is when I add widgets to my layout the scroll area begins to scroll and does not expand when it has room to expand. I  want the scroll area to expand to its limit before the scroll bar appears first.</p>
  
  <p>How can I get the scroll area to expand before the scroll bar appears?</p>
