Hi Scott, The selection brush does indeed have priority. How do you plan to show to the user which item is selected? Maybe you don’t need selection at all, in which case turning selections off entirely might be the way to go. The clean approach would be to subclass QItemDelegate (or QStyledItemDelegate) and to override QItemDelegate::drawBackground. Note that the default delegate doesn’t assume that it has to care about the item’s BackgroundRole value if the item is selected (so setting e.g. a semi-transparent brush for the Highlight role won’t work).
