QTableVIew shows number with commas but model->data(index).toString shows dots

[polrus]

Hi
I have a QTableView that gets its content via QSqlQueryModel as the source.
It shows nice decimals in my locale

ITEM NUMBER
a 2,33
b 7,88
c 12,33


but when I access
table->model()->index(i,j).data(Qt::EditRole).toString()
or
table->model()->index(i,j).data(Qt:isplayRole).toString()

I get

ITEM NUMBER
a 2.33
b 7.88
c 12.33

any suggestions?
