The code provided in documentation page http://qt-project.org/doc/qt-4.8/model-view-programming.html#view-classes has a bug. The code:

int main(int argc, char *argv[]){

QApplication app(argc, argv);

// Unindented for quoting purposes:
QStringList numbers;
numbers << "One" << "Two" << "Three" << "Four" << "Five";

QAbstractItemModel *model = new StringListModel(numbers);

Here the StringListModel should be QStringListModel.
