How to set background color one row in TableWidget?

Hi,

I've a TableWidget:

Code:

---

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 :/

Code:

---

TableResult = new QTableWidget;
TableResult->setRowCount(10);
TableResult->setColumnCount(5);
 
QTableWidgetItem *tmpItem; //why create a new item on the heap in every loop pass?
QBrush blue(Qt::blue);
QBrush red(Qt::red);
 
for(int c=0;c<4;c++) {
      for(int r=0;r<9;r++){        
        tmpItem= new QTableWidgetItem(tr("%1 x %2").arg(c + 1).arg(r + 1));
 
        if (r % 2 == 1)
             tmpItem->setForeground(blue)
        else
             tmpItem->setForeground(red);
        TableResult->setItem(r, c, tmpItem);
      }
  }

There you have it, pretty simple.
But if you really just want to alternate the row colors, this would be much better.


Edit:
I almost forgot: you're starting with 1 in both your for-loops. Remember that the TableWidgets indexes start at 0 and end at rowCount - 1. I have corrected that, s.a.

Edit 2:
Of course you can use a delegate with a QTableWidget, it's also part of the model-view architecture.

Thank you,

I've wrote, I fourtunately havent't use model-view-delegate architecture.
