data-aware widgets

Hi, I'm really a newbe in QT world! I'm creating a software that manage data from a DB and presents it to the user. I'm using some Model/View Widgets but I'd like to connect them with a "datasource"... I mean: I have a comboBox that display a item name, and I like to populate some text-fields with item-details.
as an expample I have a table with (ID, name, description, price), in my comboBox I need to display only "name" column, and when user chooses another "name" I need to populate some (read-only) text-fields with description and price. Is there any widget that do that "automatically"?

Regards!

You can use an SQL model with QComboBox, and QDataWidgetMapper might be handy whilst mapping widgets to certain fields.

Thank you so much! For completeness I report a code (found in QT docs) to do what I mean (for future reference)

Code:

---

QDataWidgetMapper *mapper = new QDataWidgetMapper;
 mapper->setModel(model);
 mapper->addMapping(mySpinBox, 0);
 mapper->addMapping(myLineEdit, 1);
 mapper->addMapping(myCountryChooser, 2);
 mapper->toFirst();

Thank you again! :)
