Two levels are most likley the most common case because most systems do not have any system administrator. Once you have admin customization you have at least three (package, admin, user). I don't have any evidence for nor against usage of Kiosk features in regard to spell checking, I am just pointing out that the solution proposed here does have none of those. I also don't think it matters that a Qt-only library would do exactly this, a Qt-only library would not have been part of a solution that offered those option in the first place. The reuse of the filename "sonnetrc" suggest to me that the intention is to use the same file. A KConfig based application and a QSettings based application will behave inconsitently if using the same file. Or is this a per-application stored file? Do we assume that KDE application developers who's programs are being used in an "Enterprise" setup will fork the library and reimplement the config with KConfig or do we want them to use the KF5 version? The later will either require that the library does not handle config itself or at least allows applications to intercept config access or provide config that takes precendence over stored config. IMHO the most sensible case is to let the application handle config I/O, allowing it to store the config in a way that is most approriate for its usage. If that is a KConfig INI file, a simple QSetting INI file or a JSON file shouldn't really matter to an engine which only is interested in the values. - Kevin ----------------------------------------------------------- This is an automatically generated e-mail.
