QTableWidget or QTableView - noneditable field

I am wondering if anyone could assist me in providing a way, such that the zeros can be not be editable when displayed in the table. QT 3.3 provided QTableItem::Never, so is there something similar for QTableWidget or QTableView

table_widget1->setItem(r, c, new QTableWidgetItem(QString::number(0)));

QTableWidgetItem::setFlags() with unset Qt::ItemIsEditable. (see bit operators) or you use a view with a custom delegate where you don't set an editor when the value is null.
