Using Qsettings to read legacy settings format and write it in QSettings format

[mstegehu]

If have an old program that uses a custom (XML like) format for reading writing settings.

I would like to use the QSettings normal format so I do not have to maintain readers and writers for that format.

So using a custom format I read the settings file and have all my key/value pairs.

Is it possible to use the same QSettings object and set the format to QSettings::NativeIni and write the settings?

QSettings::setDefaultFormat (QSettings::IniFormat); ignores IniFormat and sets the format to the one specified with the creation of the settings object and thus the Custom format that I want to get rid of.

Now I think I have to create a new QSettings object and read/write all values from the old settings object to the new one to be able to save to Ini.

Regards,

Marcel

Yes, you can't change the backend of an existing object. You have to copy all the data to a new object. QSettings::allKeys() will be helpful.
