title: PyQt Collection of QLineEdit objects
body: <p>Is there some way in PyQt to get a collection of all <code>QLineEdit</code> objects?</p>
  
  <p>I am trying to add a reset button that will blank out all text in all <code>QLineEdit</code> on a form, so I am looking for a way to loop through all <code>QLineEdit</code> objects rather than listing them all in my reset function that will connect to the reset button.</p>
  
  <p>Thank you.</p>
