[Qt-interest] QSqlDatabase lastError method when using QDataWidgetMapper

[bar tomas]

Hi,

I'm trying to use the lastError method of the  QSqlDatabase  class to
retrieve errors from insert statements sent to my database using a
QDataWidgetMapper and a QSqlRelationalTableModel.
Although I know there is an error with one of the insert statements
(violates foreign key constraint and no row is inserted in the
database) when I try to print the error, with lastError  that I call
after the submit method of the QDataWidgetMapper , only an empty
string is returned. Does lastError not work with a QDataWidgetMapper?

Many thanks
