How to go about saving?

[JohannesMunk]

Ok if you insist you can loop through the children of your mainwidget! But thats not really good design! But definitely better than hard coding!

int i = 1;
QDateEdit *de;
do
{
   de = parentWidget->findChild<QDateEdit *>(QString("dateEdit_%1").arg(i));
   if (de) {
      ...
   }
   ++i;
} while (de);

int i = 1;
QDateEdit *de;
do
{
   de = parentWidget->findChild<QDateEdit *>(QString("dateEdit_%1").arg(i));
   if (de) {
      ...
   }
   ++i;
} while (de);
