Qsettings

The application is being rewritten to be deployed on different machines over the network...

Oh, I see now. In that case I think your tactic of writing your own class using the QSettings API is a good one.

Unfortunately simply subclassing QSettings won't help you because none of its methods are virtual. I think you should just implement a class simmilar to QSettings and substitute all occurences of QSettings in the code. Of course your class can still use QSettings to provide compatibility with the "usual" settings storage methods.

I ... wrote my own class that has a similar api to QSettings

Thanks, I did

Right but there is a static method called registerFormat() that allows the creation of custom settings format without changing anything in the API, just implementing to functions...

But, registerFormat() assumes that the format is of a file on the hard disk, you can't change that, of course you could set the file to /dev/null, or something but you'll have all sorts of issues or at least lost functionality with the conflict/locking stuff that Qsettings uses, plus it really isn't designed for it.

What I wanted was to store the data in a database, regardless of format (meaning I don't care about the format, not I want a generic use any format class). To do that I implemented a new (not derived) class which has a similar, but not entirely same api as QSettings, this enabled me to migrate a very large codebase over a day or so.
