Is it necessary to setDomainName and other stuff ?

[Alir3z4]

Hi
is it really necessary to set

QCoreApplication::setOrganizationName("OrgName");
QCoreApplication::setOrganizationDomain("DomainName.com");
QCoreApplication::setApplicationName("ProjectName");

QCoreApplication::setOrganizationName("OrgName");
QCoreApplication::setOrganizationDomain("DomainName.com");
QCoreApplication::setApplicationName("ProjectName");

To copy to clipboard, switch view to plain text mode 

I just want to use QSetting, and i don't have any domain or organization.
What do you prefer to do?
Thanks
