title: PySide, editing spinbox colors
body: <p>How in PySide would you edit the background color of the field of a spinbox, using stylesheets, but not change the color of the up-button and the down-buttons? Is there a flag to only adjust the "field?"</p>
  
  <pre><code>self.intensity_multiplier_spinbox_list[iter].setStyleSheet("QDoubleSpinBox {background-color: orange;color: black};")
  </code></pre>
