I have created my own delegate to be able to have a custom style for my QListWidgetItem's. Now I want to use alternatingRowColors for the QListWidgetItem's but I'm not sure how to change the paint method in my delegate to get alternatigRowColors working. How can I change the background color if the row is alternating?

This is how my code for paint method looks like (a little bit simplified):
Qt Code: 
  1. void ListDelegate::paint ( QPainter * painter, const QStyleOptionViewItem & option, const QModelIndex & index ) const{
  2. 		QRect r = option.rect;
  3.  
  4. 		if(option.state & QStyle::State_Selected){
  5. 			painter->setBrush(QBrush(Qt::red, Qt::SolidPattern));
  6. 			painter->drawRect(r);
  7. 		} else {
  8. 			painter->setBrush(QBrush(Qt::white, Qt::SolidPattern));
  9. 			painter->drawRect(r);
  10. 		}
  11.  
  12. 		//GET TITLE
  13. 		QString title = index.data(Qt::DisplayRole).toString();
  14.  
  15. 		//TITLE
  16. 		r = option.rect.adjusted(45, 0, -10, -30);
  17. 		painter->setFont( QFont( "Arial", 6, QFont::Normal ) );
  18. 		painter->drawText(r.left(), r.top(), r.width(), r.height(), Qt::AlignBottom|Qt::AlignLeft, title, &r);
  19. 	}
