title: Color tag not working on QPushButtons
body: <p>I am in the process of styling buttons in my user interface, using the UI designer in QT Creator 3.0.1 (with QT 4.8).  I am trying to have these buttons behave more like links on a website--without borders, and responding to mouse hovers.  Here is the stylesheet I am currently using:</p>
  
  <pre><code>QPushButton {
      border: none;
      color: #a8a8a8;
  }
  
  QPushButton:hover {
      color: #ffffff;
  }
  </code></pre>
  
  <p>I thought it was pretty straightforward, but for some reason the color tag is not functioning on hovers.  To test, I tried changing the button in other ways, such as changing the background color, and that worked flawlessly.
  I also tried changing the selectors to something more specific, by including an ancestor (<code>QWidget QPushButton:hover</code>) and by using the ID (<code>QPushButton#templateButton</code>), but neither have worked.</p>
  
  <p>Is this a problem with the color tag, or am I missing something obvious?</p>
