 GObject is an object system based on GType type system. Types in it are identified by an integer value of type @code{GType}. In @code{cl-gtk2-gobject}, types are identified by GType designators. GType designator is an integer (equal to corresponding GType identifier) or a string (equal to the name of corresponding type). The important difference between GType and GType designator is that GType values may change between program runs (all GTypes except fundamental GTypes will change values), but string GType designators do not change (because names of types do not change). As such, if ever GType must be saved in a code, string GType designator should be preferred.
