title: Same style for QPushButton and QToolButton during mouse-over
body: <p>Is it possible to make QPushButton and QToolButton look identical during mouse-over, i.e. the look and feel for hover events?</p>
  
  <p>I don't use custom stylesheets, but there is a global application setting:</p>
  
  <pre><code>QtGui.QApplication.setStyle("plastique")
  </code></pre>
  
  <p>I'm looking for something like "propagate" the current (system-default) mouse-over-stylesheet of a QPushButton to a QToolButton. By default, a QPushButton will be highlighted during mouse-over, while a QToolButton does nothing at all.</p>
  
  <p>Environment: Qt 4.8.6, running on Linux CentOS 6 and Windows 7</p>
