QTableView change row color based on a value

Question

I have a QTableView that I implemented with my own model subclassed from QAbstractTableModel. I want to be able to change the row color to red when one of the fields in the row has a certain value. I saw a lot of examples where the answer is to call the models setData and use Qt::BackgroundRole to change the background color. Since I subclassed the AbstractTableModel I reimplemented setData and data so calling models setData does nothing with the background color role since I'm only handling data whose role is Qt::DisplayRole.

I guess my first question is : Is there an easier way to change the color of the entire role? If not, I'm guessing I have to implement that part in setData and data to handle the BackgroundRole which I have no idea how to do so if anyone has examples on how to do this it would really help a lot...
