Yo can try to make a QSettings wrapper class with QDeclarativeItem.
There is no built-in solution for local storage.

Well, there is SQL local storage, documented here http://doc.qt.nokia.com/4.7/qdeclarativeglobalobject.html#offline-storage-api

Cheers,

There is some work on this for Qt 5 AFAIK, but for Qt 4 you don't have it.

My solution has so far been to have a QObject derived class that reads
and writes with QSettings. I expose this singleton object to the qml and
it has properties for each of the settings.

I'm not thrilled about this solution, so if someone else has a better
one, I'd love to hear about it.

If you take a look at the examples, you will see that some of them has
settings in a javascript file. This is basically the same idea as mine,
just done in javascript instead of c++. No better, no worse, IMHO, and
still not great.
