In this specific case, I'd like to use the full name of the currently logged-in user in a QML app (not the logname). As far as I found out, system calls can not yet be used (and would not be an elegant solution). Also the Ubuntu SDK documentation seems to cover only UI-related topics.
Is there a method to access the full user name from within a QML app? And in general, are system APIs or the Unity API available to QML apps?
