Qsettings does not differentiate between string and int values

[anda_skoa]

What is a backend?
Are you referring to QSettings::SetIniCodec?

No, QSettings would be one possible backend for storing values.

Other alternatives would be JSON, XML or some custom storage format, e.g. using QDataStream.
Even with QSettings as the backend, you could store the type as a subkey of the value.
