QDataWidgetMapper and QComboBox

I have the classical QSqlRelationalTableModel situation where the customerModel is the master and the countryModel is the detail. The problem is that I don't want to display this model in a table, but show one record at a time in individual widgets using the QDataWidgetMapper.

How do I wire up the QComboBox that allows the user to pick the country?

Possible options:

1. Make the customerModel a QSqlTableModel, pass a 3rd param to the addMapper function
2. Make the customerModel a QSqlRelationalTableModel, wire up the relationship, and Qt does the rest.
3. something else

Use QSqlRelationalDelegate on the widget mapper.

Ok, let me see if I understand what you mean.

1. the customerModel needs to be QSqlRelationalTableModel
2. Wire up the relationship to the countryModel
3. Create a QDataWidgetMapper
4. Make the mappers delegate the QSqlRelationalDelegate
5. Add a mapping for the QComboBox

Correct?

Yes, something like that.

Tried that and it did not work :(
