After reading the forum post, I have a more complete answer; posting here for
If your Qt4 code does the above, in Qt5 you can either:
* move the data once and for all (from data/org/app to org/app)
* keep using the deprecated QDesktopServices::DataLocation
* port to this instead:
QStandardPaths::writableLocation(GenericDataLocation) + “data/org/app”.
The latter is the future-proof way of accessing that (old) data/org/app
directory under local/share, for people who don't want to move it.
Please confirm that this solution works for you, and I'll add porting
documentation to QDesktopServices about this solution.
I withdraw my suggestion of a Qt4DataLocation because this is basically what
QDesktopServices::DataLocation is. IOW, the compat code already exists, it's
exactly there in QDesktopServices -- and there is another difference than the
"data" subdir, it's what happens when the applicationName isn't set, in Qt4 it
was empty, in Qt5 it comes from the executable name.
