This component will load either the gb.qt4 or the gb.gtk component, according to the current desktop in use.

• If you use KDE 4, then gb.qt4 will be loaded.
• In all other cases, gb.gtk will be loaded.

If the GB_GUI environmental variable is defined, then gb.gui will load the component specified in it, whatever desktop is currently used.

See the gb.qt4 component for the documentation of classes.
