title: Is it possible to seamlessly display an ajax spinner for every GWT RPC call?
body: <p>I have a GWT application that uses RPC calls heavily. I would like to display a spinner icon whenever a call is in progress. It is easy enough to display the icon, but I want to do it seamlessly in one place so I don't have to explicitly hide and show the icon for each call.</p>
  
  <p>I guess I am looking for something similar to jQuery's ajaxStart and ajaxStop events.</p>
  
  <p>Has anyone done something like this before?</p>
  
  <p>Cheers
  Tin</p>
