How to add rows automatically with sleep?

[SoleyRan]

Hi everyone, I want to make my tableview to show rows automatically. The target is everytime the table shows 10 rows, then sleep 1s, then add 10 rows and continue...
I used QThread::sleep(1) in my loop, but it would not show data until all data was loaded, but what I want is showing data while loading.
My part code for testing this function is:

QVector<QVector<QVariant>> d;
    for (int t = 1; t <= 10; t ++)
    {
        d.clear();
        for (int i = 0; i < 10; i++)
        {
            QVector<QVariant> row;
            row.clear();
            for (int j = 0; j < 3; j++)
                row.append(i*j*t);
            d.append(row);
        }
        tablemodel->addData(d);      //addData is used to add all new data to model
        QThread::sleep(1);
    }

Please help me. Thanks in advance! :)

You're blokcing the event loop.
Use a QTimer to add the rows later - whyever this should be needed at all.
