如何编写flash的右键菜单

请参考以下程序：（对了，你要把下面的这段代码复制到时间轴的第一帧）

function url0() {
 qq_mc.gotoAndPlay(2);
}
function url1() {
 getURL("http://www.upflash.cn", "_blank");
}
function url2() {
 getURL("mailto:upflash@163.com", "_blank");
}
function url3() {
 getURL("http://www.blog.edu.cn/user2/upflash/", "_blank");
}
function quit1() {
 fscommand("quit", "");
}
var expandmenu = new ContextMenu();
expandmenu.hideBuiltInItems();
var $url0 = new ContextMenuItem("我的QQ:75668714", url0, true, true, true);
var $url1 = new ContextMenuItem("www.upflash.cn", url1, true, true, true);
var $url2 = new ContextMenuItem("upflash@163.com", url2);
var $url3 = new ContextMenuItem("我的博客", url3);
var $url5 = new ContextMenuItem("退出", quit1, true, true, true);
//var $url5 = new ContextMenuItem("退出"[名称], quit1[调用函数],true[显示分割符号], true[灰色], true[显示/隐藏]);
expandmenu.customItems.push($url0, $url1, $url2, $url3, $url5);
expandmenu.onSelect = menuHandler;
_root.menu = expandmenu;
