QColumnView - setEditTriggers(QAbstractItemView::NoEditTriggers) has no effect on the first column items

When executing setEditTriggers(QAbstractItemView::NoEditTriggers) for a QColumnView the items in the first (leftmost) column remains editable. The items in the other columns become read only as expected.

Include a test case to reproduce

A workaround for this issue is to use MyColumnView instead:

class MyColumnView : public QColumnView
{
protected:
    QAbstractItemView *createColumn ( const QModelIndex & index )
    {
        QAbstractItemView *v = QColumnView::createColumn(index);
        v->setEditTriggers(QAbstractItemView::NoEditTriggers);
        return v;
    }
};
