Default location of the settings file on windows when using KXmlGuiWindow/KMainWindow

[Alexander Semke]

Hi all,


https://bugs.kde.org/show_bug.cgi?id=387626
we've got this problem reported and I don't see how to easily fix this.
LabPlot's MainWindow inherits from KXmlGuiWindow. When saving the auto
settings in KMainWindow, KSharedConfig::openConfig() is used which uses
QStandardPaths::GenericConfigLocation for the location:
https://api.kde.org/frameworks/kconfig/html/classKSharedConfig.html#a328208649f2e3f0ee895c9b11aa82205

According to the problem description in this ticket, I assume this is a
valid request since it makes a lot of sense to me, we have to use
QStandardPaths::AppDataLocation for the location of the config file. Do
I need to set here KMainWindow::setAutoSettings() with a KConfig having
the proper name and location? I'd actually expect this to be done by the
underlying framework(s)...

We read the settings in many places via KSharedConfig::openConfig()
which also defaults to the same rc file under
QStandardPaths::GenericConfigLocation. For all our custom and
application specific settings we can of course provide AppDataLocation
explicitely but this also looks to me like not the most optimal solution
since we'd need to touch the code at many places. How is this handled in
other KF5-applications? Can somebody share some best practices here?


Thanks and Regards,
Alexander
