- * GnomeIconList widget - scrollable icon list
- *
- * Authors:
- * Federico Mena <federico@nuclecu.unam.mx>
- * Miguel de Icaza <miguel@nuclecu.unam.mx>
- *
- * Rewrote from scratch from the code written by Federico Mena
- * <federico@nuclecu.unam.mx> to be based on a GnomeCanvas, and
- * to support banding selection and allow inline icon renaming.
- *
- * Redone somewhat by Elliot to support gdk-pixbuf, and to use GArray instead of GList for item storage.
