            item->setBackground(b);
            model->setItem(MsgIDlist.size(),i,item);
    }
}
    q1.clear();

    showdia->setFixedSize(300,220);
    showdia->show();

To copy to clipboard, switch view to plain text mode

Try something like the following:

model->setData(model->index(row, column), Qt::blue, Qt::BackgroundRole);

model->setData(model->index(row, column), Qt::blue, Qt::BackgroundRole);
