An EiffelVision 2 "item" is an object that is used to display information inside certain primitives. For example, [[ref:libraries/vision2/reference/ev_list_chart|EV_LIST]] may hold items of type [[ref:libraries/vision2/reference/ev_list_item_chart|EV_LIST_ITEM]]. All EiffelVision 2 items are descendants of [[ref:libraries/vision2/reference/ev_item_chart|EV_ITEM]], which in turn is a descendant of [[ref:libraries/vision2/reference/ev_pixmapable_chart|EV_PIXMAPABLE]], which means that an item can display a [[ref:libraries/vision2/reference/ev_pixmap_chart|EV_PIXMAP]] object.
