Qt: how to make the editor in the table behave differently when pressing Tab?

Question

Qt

I already asked a question about this: Qt: how to check if a combobox is expanded?
So, the combobox editor in QTableView is set up. But the questions continue. It turned out that the editor behaves funny when you press Tab: it just jumps to another table cell. You should jump to the next component in tab order.
tabKeyNavigation for the table is, of course, disabled. If the cursor is on a non-editable cell (there are some), everything is in order.

Answer 1

QModelIndex EditableTable::moveCursor(
        CursorAction cursorAction, Qt::KeyboardModifiers modifiers)
{
    switch (cursorAction) {
    case QAbstractItemView::MoveNext:
    case QAbstractItemView::MovePrevious:
        return QModelIndex();
        break;
    default:
        return Super::moveCursor(cursorAction, modifiers);
    }
}

To push such functionality into Qt Creator, use the "Promote To..." function

Answer 2

Then write your own class inherited from QTableView, in the keyboard handler of which you will write everything as you like)
