No, I think you misunderstood. I'm not saying change the style, I said
take the styleoption argument that is passed to the paint() method and
adjust its color palette depending on the type as you wish. Then pass
the modified object on to QItemDelegate's standard paint() function.
This will only affect the listviews on which you set an instance of your
own item delegate, which is what you want - right?
