title: Infinite background while loop in PyQt
body: <p>I want to write a QT program in Python and it is supposed to continuously look for updates. Just like </p>
  
  <pre><code>while(True):
     doSomething()
  </code></pre>
  
  <p>would do in a console based program.</p>
  
  <p>Is there a specific slot which I can connect to for this purpose?</p>
