[TomASS]

Hi,

I've a TableWidget:

TableResult = new QTableWidget;
TableResult->setRowCount(10);
   TableResult->setColumnCount(5);
  for(int c=1;c<5;c++){
      for(int r=1;r<10;r++){
        QTableWidgetItem *tmpItem;
        tmpItem= new QTableWidgetItem(tr("%1 x %2").arg(c).arg(r));
        TableResult->setItem(r, c, tmpItem);
      }
  }

TableResult = new QTableWidget;
TableResult->setRowCount(10);
   TableResult->setColumnCount(5);
  for(int c=1;c<5;c++){
      for(int r=1;r<10;r++){
        QTableWidgetItem *tmpItem;
        tmpItem= new QTableWidgetItem(tr("%1 x %2").arg(c).arg(r));
        TableResult->setItem(r, c, tmpItem);
      }
  }

How to set background color rows number 1, 3, 5, 7, 9 to (example) blue, and rows number 2,4,6,8 to red?

If I had a model-view-delegate pattern, I could do it in delegate, but I've any view, any model, any delegate :/
