Set current index of QComboBox inside QTableWidget

I have QComboBox inside QTableWidget. It was created like this:

QComboBox* bb = new QComboBox(this);
ui->propsWidget->setCellWidget(1, 0, bb);
for (...)
    bb.addItem(...);

I need to set its index programmatically. I've tried this:

QComboBox* bb = qobject_cast<QComboBox*>(ui->propsWidget->cellWidget(1, 0));
bb->setCurrentIndex(5);

and this:

bb->setEditText("mytext"); // "mytext" is contained in bb

but the current index is not changing. How can I do that?

You need to modify this line: QComboBox* bb = new QComboBox(this); because QTableWidget takes the ownership of all its subcomponents. So, it must become QComboBox* bb = new QComboBox();, and the parent will be the table on its own.
