[Qt-interest] Locale input/output of custom doubleSpinbox Delegate

[Matthias Pospiech]

I created a class DoubleSpinBoxDelegate which is simply a delegate using 
a QDoubleSpinBox.

Now if I insert data into a tableview table, it is in english format 
"10.123",
If I edit it the result is returned in locale (german): "10,123".

So I thought to insert the values in the table directly in german format.
If I then edit the value is returns 0 as a value in case there was a dot 
and a comma as in "40.000,123".

How can I solve this problem?
