title: color of QPushButton or QToolButton
body: <p>I am using a Qstylesheet to control the behavior of some QPushButtons and QToolButtons.  When I hover over them, they turn black, as I want them to.  However, once I press them, they turn a funny greyish reddish color, and there is a red box drawn inside of them.  </p>
  
  <p>What is the property or pseudo state that I have to set in order to avoid this behavior?  I have been through all the properties related to selection, and background, and cant get this to go away</p>
