Hi Mark,
thank you for your response!
I have been looking at the QItemDelegate class but am pretty unsure what method
to override.
Can you point me to the right direction?
Thank you in advance
Stefan

That's right, this is about the behavior of QDataWidgetMapper (sort of a
"view") not the model. The OP wants changes to be submitted to the model even
if the focus never leaves the mapped widget.
I'm pretty sure that this default behavior of QDataWidgetMapper is actually
defined by the delegate, which is QItemDelegate by default. You could use
QDataWidgetMapper::setDelegate() to use your own subclassed delegate instead.
regards,
Mark
