It appears, from Marko's other emails, that file ui_standards.rc is in <blahblah>/etc/xdg
in sub-directory "ui". I don't know if that is where things like bovoui.rc (the Bovo menu
and toolbar structure) would go. Anything with "etc" in it sounds a bit "system-y" to me,
as opposed to "application-y". QSP's only "prescription" for ConfigLocation and also
GenericConfigLocation in OS X is "~/Library/Preferences" and we cannot very well
install <appname>ui.rc files there. QSP prescribes for Linux "~/.config", "/etc/xdg".
I think it is good, BTW, that "~/.config" is now separate. In the past I have heard
grumbles from Linux sysadmin guys about KDE 3 and 4 intermixing config and
user-data files under the same ~/.xxx prefix.

Good thought. I would even be so radical as to suggest that we build the source file
"qstandardpaths_unix.cpp" into Macports' Qt 5, rather than "qstandardpaths_mac.mm".
The former might be easier to modify to suit Macports and it incorporates the $XDG_*
environment variables at ground level, which would help us with test versions of
Qt5 and KF5 apps, libraries and utilities.

Well MacPorts has a bet each way. In my KGoldrunner example, it installs read-only
files in /opt/local/share/apps/kgoldrunner (pure KDE 4 style) and finds writeable files
in ~/Library/Preferences/KDE/share/apps/kgoldrunner (a bit of OS X, a bit of KDE 4)
and has application-icons in
(pure OS X).

I agree, except that the application folder, bundle and .icns have to go where OS X wants them.

You mean files or directories with the same name but different case-mix? Not good.

I think this is part of an early move towards Frameworks, KF5 and XDG. I also notice
that I have to have XDG_DATA_DIRS set in my KDE 4 development setup if I want
to find all the mime types.
