Thanks Scott for advices,
- 10 times checked that there was no typo
qdesktopservices do not provide path to common application data folder,
only to user specific.
Reason I guess that there is no such concept on unix derived systems.
I finally did write an extension to it which on Windows returns value I am
looking for
basically it is call to SHGetSpecialFolderPath with CSIDL_COMMON_APPDATA
parameter.and on Linux returns results obtained with
QDesktopServices::DataLocation
This is supposed to be a right way to dt it anyway (besides extending
qdesktopservices which would be probably even better) ,
but it does not explain problem I see with QSettings
Regards,
Alex
