title: PyQt4 names showing as undefined in eclipse, but it runs fine
body: <p>I am using Eclipse 3.7.1 with the latest PyDev add-in for Python coding. I am using PyQt4. At the top of my file I have:</p>
  
  <pre><code>from PyQt4.QtCore import *
  from PyQt4.QtGui import *
  </code></pre>
  
  <p>In addition, I have the PyQt4 tree included in the Project Explorer listing. However, eclipse still thinks the names like QMainWindow are undefined. The code runs fine. How may I get eclipse to recognize those names.</p>
  
  <p>Thanks</p>
