I'm stuck with QT 4.8.5 at the moment so QStandardPaths is not
available, but I could use QDesktopServices instead, e.g.:
QtGui.QDesktopServices.storageLocation(QtGui.QDesktopServices.HomeLocation)
What would be the difference to os.path.expanduser('~') though?

Hi Frank.
Looks like the host application uses QSettings::setPath()
(http://doc.qt.io/qt-5/qsettings.html#setPath) to enforce a specific
directory for configuration files. Calling that method from your code is
obviously a bad idea (high risk of screwing up the host application), so
your "fallback" is the easiest solution. It'll be even better if you
replace the "~/.config" part with proper runtime detection of user
settings' directory (e.g.
QStandardPaths::writableLocation(QStandardPaths::GenericConfigLocation)).

While this does not give me the OS' native support directory for the
respective user at least it's consistent :)
I'd still be interested in a QSettings solution though.

Hi all,
I have been using QSettings for reading/writing user settings.
All works well until I run my (PySide) application inside a host
application that is also written in QT, and which also uses the
QSettings object.
I am now struggling to understand how I can properly differentiate
between the host application's settings instance and my own.
In particular, I need to use QSettings().fileName() to determine the
correct support path for my ini files for each platform.
But this line gives me different values inside and outside the host
application:
QtCore.QSettings(QtCore.QSettings.IniFormat,
QtCore.QSettings.UserScope, "companyName", "appName").fileName()
E.g.:
Outside the host application I get what I want:
/Users/frank/.config/companyName/appName.ini
But the return value is a completely different inside the host app and
actually points to the host app's internal file structure.
Fair enough too I guess.
So my question is:
How can I use QSettings to determine support paths etc while making
sure that I don't accidentally mess with the host applications QSettings?
