title: Set font using stylesheet for QComboBox with QStandardItemModel
body: <p>I have QComboBox and a stylesheet that sets the font size for QComboBox. Previously i added items to QComboBox using 'addItem', but due to performance issue i am using Model view model for my QComboBox<br></p>
  
  <pre><code>QStandardItem modelItem = new QStandardItem;
  modelItem-&gt;setText("TEST");
  QStandardItemModel model = new QStandardItemModel;
  model-&gt;appendRow(modelItem);
  QListView listView = new QListView;
  
  comboBox-&gt;setView(listView);
  comboBox-&gt;setModel(model);
  </code></pre>
  
  <p>This is roughly how my code looks like. How do i use stylesheet to increase the font size in the list when i click on my combo box? My previous stylesheet works okay, until i motified my code to use QStandardItemModel and QListView.</p>
