Good morning all,
does anyone know, how to color the QTableViews header by using the standard delegate in Qts MV architecture? I tried this by using the roles as it does in the data() method, but in the headerData() nothing happens :-(

Qt Code: 
  1. QVariant SchulungsplanModel::headerData(int section, Qt::Orientation orientation, int role) const
  2. {
  3. 	// HORIZONTAL HEADER: (timeline)
  4. 	if (orientation == Qt::Horizontal)
  5. 	{
  6. 	   if(role == Qt::BackgroundRole)
  7. 		  return QVariant(QBrush(QColor(Qt::green), Qt::SolidPattern));
  8.  
  9. 		if(role == Qt::DisplayRole)
  10. 		{
  11. 			if (section < m_horizontalHeaderList.size())
  12. 				return m_horizontalHeaderList.at(section);
  13. 		}
  14. 	}
  15.  
  16. 	// VERTICAL HEADER: PUs
  17. 	if (orientation == Qt::Vertical)
  18. 	{	
  19. 		if(role == Qt::DisplayRole)
  20. 		{
  21. 			if (section < m_verticalHeaderList.size())
  22. 				return m_verticalHeaderList.at(section);
  23. 		}
  24. 			}
  25.  
  26.    return QAbstractTableModel::headerData(section, orientation, role);
  27. }
