自定义Flex右键菜单

隐藏系统自带右键菜单，增加自定义菜单，用到RightClickManager。实现如下：

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"
	creationComplete="init()">

	<mx:Script>
        <![CDATA[
        	import mx.events.MenuEvent;
        	import mx.controls.Menu;
        	import com.siloon.plugin.rightClick.RightClickManager;

        	private var menu:Menu;

        private function init():void{
        	//隐藏系统右键菜单
			RightClickManager.regist();

			//创建新右键菜单
			this.addEventListener(RightClickManager.RIGHT_CLICK, rightClickHandler);
        }

        private function rightClickHandler(event:MouseEvent):void{
        	removeMenu();

        	menu = new Menu();
        	menu = Menu.createMenu(this, createMenuItems(), false);  

    		menu.labelField="label";
    		menu.variableRowHeight = true;     
    		menu.addEventListener(MenuEvent.ITEM_CLICK, menuItemClickHandler); 

    		var point:Point = new Point(mouseX,mouseY);  
    		point = localToGlobal(point);   
    		menu.show(point.x,point.y);   

        } 

        private function removeMenu():void{  
   			if(menu!=null){  
        		menu.hide();  
        		menu.removeEventListener(MenuEvent.ITEM_CLICK,menuItemClickHandler);   
        		menu=null;  
    		}  
		} 

        private function createMenuItems():Array{  
   			var menuItems:Array = new Array();  
    		var menuItem:Object;   

    		menuItem = new Object;  
    		menuItem.label = '菜单一';  
    		menuItem.action = 'menu1ClickedAction';  
    		menuItems.push(menuItem);   

    		menuItem = new Object;  
    		menuItem.label = '菜单二';  
    		menuItem.action = 'menu2ClickedAction';
    		menuItems.push(menuItem);   

    		return menuItems;  
		}  

		private function menuItemClickHandler(event:MenuEvent):void{
			//TODO  增加菜单选择事件的响应

		}
