title: Pyside Remove window flags
body: <p>Im designing a Pyside Qt application and I want to toggle the <code>QtCore.Qt.WindowStaysOnTopHint</code> window flag in my main window. Setting this hint using this code works fine:</p>
  
  <pre><code>self.setWindowFlags(QtCore.Qt.WindowStaysOnTopHint)
  self.show()
  </code></pre>
  
  <p>but I can't work out how to remove a window flag using Pyside.</p>
  
  <p>Does anybody know how to do this?</p>
