title: See which style of stylesheet is applied to particular element
body: <p>I use stylesheets (<code>qss</code>) with my Qt application. Is there a way to see which style is applied to a particular element (widget)? I can use trial and error, but it was much easier if I could just see which style is used / applied.</p>
  
  <p>The <code>styleSheet</code> property itself is empty. So is there a way to debug which style from the stylesheet is exactly applied? </p>
