This way the other parts of the # GUI have to check the version in use very rarely. The variable \c pygobject # tells which version is being used. If it is \c True, Gtk+ 3 is used via the # PyGObject interface. Otherwise Gtk+ 2 is used, which is the default on # Windows or when the \c FORCE_PYGTK environment variable is set. # # Besides this there are some common utility classes and functions.
