public class listbox_v_scrollbar
extends v_scrollbar

This class implements the vertical scrollbar for a listbox. It is subclassed from v_scrollbar and its only modification is that it understands that the buttons of the vertical scrollbar should cause the system to move to the next object in the list.

This is also a reasonable demo of how to get custom behavior out of the scrollbars' buttons.

Field Summary
`protected listbox_display`	`_display` The listbox we are attached to.
