In the Qt Reference documentation / QDataWidgetMapper Class Reference / Detailed Description:

"After the call to toFirst(), mySpinBox displays the value 1, myLineEdit displays Nokia Corporation and/or its subsidiary(-ies) and myCountryChooser displays Oslo. The navigational functions toFirst(), toNext(), toPrevious(), toLast() and setCurrentIndex() can be used to navigate in the model and update the widgets with contents from the model."

"Nokia Corporation and/or its subsidiary(-ies)" should say "Qt Norway" to agree with the table shown above the text.
