C/C++ :: Qt TableView Change Row Color

I'm creating a simpe program using Qt/C++ and MySQL.

I am trying to change row color of QTableView, but it has to change depending on value on the database.

For example I have QTableview wich is conected to mysql database:

this->model1 = new QSqlQueryModel();
model1->setQuery("SELECT ID, value, Name FROM DB_Table ");
ui->tableView->setModel(model1);

Now I want to change row color to red if the value = 1 .

I searched alot and found this:My link But dont understand how to use these clases in my code, i'm cind a new in programing.
