AS3 Flash禁止右键等相关按钮

想放上一些自己的资料

var contextMeumItem1:ContextMenuItem =new ContextMenuItem("欢迎光临");
var contextMeumItem2:ContextMenuItem =new ContextMenuItem("作者：余姚小金");
 var myMenu:ContextMenu =new ContextMenu();
myMenu.hideBuiltInItems();
myMenu.customItems.push(contextMeumItem1);
myMenu.customItems.push(contextMeumItem2);
 contextMenu=myMenu;

什么都不填写

var b:ContextMenuBuiltInItems =  new ContextMenuBuiltInItems();
b.loop = false;
b.print = false;
b.play = false;
var a:ContextMenu = new ContextMenu();
a.builtInItems = b;
a.hideBuiltInItems();
this.contextMenu = a;
