QSettings will still fall back onto any child groups specified in the fallback entries even if fallbacks are turned off

QSettings will still fall back onto any child groups or child keys specified in the fallback entries even if fallbacks are turned off.

–
Example:

#include <QCoreApplication>
#include <QSettings>
#include <QStringList>
#include <QDebug>

int main(int argc, char *argv[])
{
QCoreApplication a(argc, argv);
a.setOrganizationName("FooSoft");
a.setOrganizationDomain("foosoft.com");
a.setApplicationName("bar");

QSettings sys(QSettings::SystemScope, qApp->organizationName(), qApp->applicationName());
sys.beginGroup("somegroup");
sys.beginGroup("someothergroup");
sys.setValue("somevalue", "somedata");

QSettings usr(QSettings::UserScope, qApp->organizationName(), qApp->applicationName());
usr.setFallbacksEnabled(false);
usr.beginGroup("somegroup");
qDebug() << usr.childGroups();
// at this point the group "someothergroup" is listed, although fallback is disabled
}
