Qt equivalent of .NET data binding?

Question

Is there an equivalent of .NET\'s data binding in Qt?

I want to populate some combo boxes and other widgets with QStrings that refer to specific entities in my database.

As the user nonchalant mentioned in a comment you can use the QDataWidgetMapper class. This is quite an easy way of binding arbitrary widgets to data that is stored in a QAbstractItemModel.

The example on the linked page shows in a few lines of code, how you can link your data model to common used input widgets:

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