The GLib structure

^________ Synopsis ^{____________________________________________________}

 signature GLIB
 structure GLib : GLIB

The GLib structure provides access to core library of GTK. As most of the facilities offered by GLib are already provided by the Alice System only a very small part of GLib is wrapped.

See the overview page for a general introduction to the GTK library binding.

^________ Description ^{_________________________________________________}

We do not give a full documentation here. We rather recommend to read the Porting Guide. It gives a comprehensive overview on what has been made available.
