title: QListView highlight color not applied to item icon
body: <p>I'm trying to get the hover highlight color I set on a <code>QListView</code> applied to the items' icons. Right now it only applies to the surroundings (the image has an alpha channel which is 0 where there is white background):</p>

  <p>You can see clearly that the 3D model itself is not affected by the highlight color. When I select the item it the image gets the selection color:</p>

  <p>And after being selected it is also affected by the highlight color (i.e. that's the result I want to produce by only hovering over the item):</p>

  <p>The stylesheet I use is the following:</p>
  <pre><code>QListView::item {
      color: #000000;
      background-color:transparent;
  }
  
  QListView::item:hover:!pressed {
      padding: -1px;
      border: 1px solid #75c1ff;
      border-radius: 2px;
      background-color: #c6e5ff;
  }
  
  QListView::item:selected {
      padding: -1px;
      border: 1px solid #5eb6ff;
      border-radius: 2px;
      background-color: #9ed2ff;
  }
  </code></pre>
  <p>This is how I'm returning the image in the <code>data</code> method of the item model of the list view:</p>
  <pre><code>return QIcon(QPixmap::fromImage(m_renderedObjectsModels.value(objectModel.path())));
  </code></pre>
  <p>I tried to add multiple <code>QPixmap</code>s there for the different states (like suggested <a href="https://stackoverflow.com/questions/5044449/how-to-change-qt-qlistview-icon-selection-highlight">here</a>) but none are applied to only hovering (at least I didn't find a state that I could add a pixmap for that would make it work).</p>
