/** \class TGuiFactory
\ingroup Base
 
This ABC is a factory for GUI components. Depending on which
factory is active one gets either ROOT native (X11 based with Win95
look and feel), Win32 or Mac components.
 
In case there is no platform dependent implementation on can run in
batch mode directly using an instance of this base class.
