import mx.controls.Menu;
// Create an XML object to act as a factory.
var my_xml:XML = new XML();
// The item created next does not appear in the menu.
// The createMenu() method call (below) expects to
// receive a root element whose children will become
// the items. This is just a simple way to create that
// root element and give it a convenient name.
var menuDP_obj:Object = my_xml.addMenuItem("XXXXX");
// Add the menu items.
menuDP_obj.addMenuItem({label:"1st Item"});
menuDP_obj.addMenuItem({label:"2nd Item"});
// Create the Menu object.
var my_menu:Menu = Menu.createMenu(this, menuDP_obj);
// Show and position the menus
my_menu.show(100, 20);
// Create listener object.
var menuListener:Object = new Object();
menuListener.rollOver = function(evt_obj:Object) {
trace("Menu rollOver: "+evt_obj.menuItem.attributes.label);
};
// Add listener.
my_menu.addEventListener("rollOver", menuListener);
