title: VS2010 Extension - code definition window
body: <p>I am listening on TextViewCreated from <code>IWpfTextViewCreationListener</code> interface.</p>
  
  <p>How can I use the <code>IWpfTextView</code> I get as a parameter to differentiate between textview belonging to the "code definition window" and the normal text editor?</p>
  
  <p>Thanks!</p>
