QSettings settings("MyCompany", "MyApp"); QStringList groups = settings.childGroups(); foreach (const QString &group, groups) { qDebug() << "Group: " << group; }
QSettings settings("MyCompany", "MyApp"); QStringList groups = settings.childGroups(); ui->comboBox->addItems(groups);In this example, the child group names are retrieved and then added to a QComboBox widget in a graphical user interface. This code uses the Qt Widgets library. In conclusion, the QSettings childGroups method is a useful Qt function for working with settings groups in an application. It can be used in a variety of contexts, from managing application preferences to populating GUI widgets.
