title: QML TableView access model properties from delegate
body: <p>I have a TableView for which I've defined my own itemDelegate. Now, from within this delegate I can access the value for the column using styleData.value, but I'd also need to access the other properties in this same item but I can't find how to. </p>
  
  <p>I need this, because the text styling needs to change depending on some other property of the item model.</p>
  
  <p>Any ideas? thanks!</p>
