Interface Elements

We will use the Graphical Interface Builder to add five interface elements needed by the scrolling list: two dragareas: "list" and "scroll_bar" (one for the list and one for the scrollbar), two buttons "list_up" and "list_down" (one to scroll up in the list, and one to scroll down), and one field: "list_fld". The width and height of "list_fld" determing the width and height of a list item.
