Detailed Description

Andrea Dotti Feb 2015 Important: This is a shared class between threads. Only one thread should use the set-methods here. Note that this is exactly what is achieved using UI commands. If you use the set methods to set defaults in your application take care that only one thread is executing them. In addition take care of calling these methods before the run is started Do not use these setters during the event loop
