[Qt-interest] Displaying NULL values using QDataWidgetMapper

[saikari keitele]

Sorry, I hadn't searched the list, although after reading the posts you
mention it is still unclear to me whether this is a bug and what the
solution to it is.
I'm sorry I don't know much Qt. Would the solution be to subclass
QSqlTableModel <http://doc.trolltech.com/4.4/qsqltablemodel.html> and to
redefine the data method?
Many thanks for any suggestions or tips.
