of course you know what Interfaces are. You've probably been dealing with Application Programming Interfaces and C headers for a long time. They represent the public functionality and data type declarations presented by an object translation unit -- the Interface to the module. In the specific case of object-oriented programming, Interfaces are simply abstract classes with just method declarations, no implementation. They can be implemented by various classes of objects, so as long as a class implements the methods presented by a given Interface, we say it implements the Interface. It's a kind of "virtual inheritence". just to illustrate how the concept of an interface is simple: /* * isorteable.h */ void sort( void *ls, int (*cmp)(void *a, void *b) ); you can then have a big variety of .c files complying with this interface, but implementing it with diverse sorting methods (merge sort, quick sort etc)... nothing new, really... _______________________________________________ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
