title: resizing of button icons in pyqt4
body: <p>I want to make image in my <code>QMainWindow</code> so when you click on it you have a signal translating like <code>qpushbutton</code> I use this:</p>
  
  <pre><code>self.quit=QtGui.QPushButton(self)
  self.quit.setIcon(QtGui.QIcon('images/9.bmp'))
  </code></pre>
  
  <p>But the problem is whene I resize the window <code>qpushbutton</code> resized too but not his icon,</p>
