I have sucessfully implemented a Table/Model view by subclassing QTableView and QAbstractTableModel. All adding, sorting and removal of table data is working great. However, I am trying to figure out how to hide a row in the table using the setRowHidden( ) fucntion. I have setup a structure in the TableModel to flag if the row is hidden or not, but the data( ) function returns a empty QVariant( ) if the cell is supposed to be hidden.
The data is stored in a 2D Vector for easy sorting. I am using a struct with a QVariant, QColor, and bool shown (hidden/not hidden) to store the data attributes. Here is the code from the data( ) function. Please ignore any obvious mistakes, I typed this in from memory since I dont have access to the code at home!

Qt Code: 
  1. QVariant StringListModel::data(const QModelIndex &index, int role) const
  2.     {
  3.         if (!index.isValid())
  4.             return QVariant();
  5.  
  6.         int row = index.row();
  7.         int column = index.column();
  8.  
  9.         if (role == Qt::DisplayRole) {
  10.             if( mDataModel[row][column].shown == false )
  11.                 return QVariant(); // <==== Return somthing other than QVariant( )???
  12.             else
  13.                QString str;
  14.                switch( mDataModel[row][column].data.type( ) )
  15.                {
  16.                case QVariant::Double:
  17.                   str = QString::sprintf( "%12.6g", mDataModel[row][column].data.toDouble( )
  18.                 case QVariant::Int:
  19.                   str = QString::sprintf( "%12d", mDataModel[row][column].data.toInt( ) );      
  20.                default:
  21.                   str = mDataModel[row][column].data.toString( );
  22.  
  23.                return str;
  24.          }
  25.         else if (role == Qt::BackgroundColorRole ) {
  26.             return mDataModel[row][column].color;
  27.         }
  28.  
  29.          return QVariant( ); 
  30.     }

What I am asking is if there is an easy way to not display the data row in an Model without completly removing the entries?

Thanks
