Upgrade grid from another thread

Upgrade grid from another thread was created by Alexander
Hello
I have an application, that displays some data in grid, that is changing over time. The number of rows always stay the same. I calculate my data in separate thread. But when I’m trying to update my model from that thread, the grid doesn’t change.
QStandardItemModel *dataFormModel;
void realObjectList::updateDataInTable(const std::vector<ModelObject>& aObjectList)
{
   if (aObjectList.size() == dataFormModel->rowCount())
      {
         for (int i = 0; i < aObjectList.size(); i++)
            {
            dataFormModel->item(i, 3)->setData(QString::number(aObjectList[i].GeogCoordinate()), Qt::DisplayRole);
            // Update other columns
            //   ...
	    }
      }
}

If I call this method in timer from GUI, it works ok. But I need to make my calculation in separate thread.

Regards,
Alex
