Taking a screen shot after a time delay after on load is done
<p>I am trying to use QtWebKit, or spynner or whatever to create a screen shot of a url.</p>

<p>Problem is that once a onload is fired...the page is still loading some flash charts.  I need a python api that will wait e.g. 30 seconds to then take the screen shot.  </p>

<p>I simple to use python api that will take a screen shot of a url and wait?</p>
