/*
 * This gadget demonstrates the listbox control.
 * 
 * Look at "main.xml" to see how the listbox is declared and configured.
 * 
 * Some interesting features of the listbox:
 * 
 * - A listbox will autoscroll when undocked or expanded if 
 *   the "autoscroll" property is set to true
 * - To disable an item, set the "enabled" property to false
 * - When an item is selected or unselected, an "onchange" event will fire
 * 
 * NOTE: This sample is not compatible with Mac Desktop Gadgets 1.0.0.0
 * because it uses the <item> element which is not yet supported.
 * To ensure a gadget based off this sample runs on the Mac,
 * change the <item> elements to <listitem> in main.xml.
