自定义Flex右键菜单

1.右键项目设置flex编译器的参数如下：

?? 其实flash player从11.版本就支持自定义右键菜单了。

?????? 设置flash player 11.3后，项目编译会出错，提示在SDK安装目录下找不到playerglobal.swc，因为不同版本的flash player对应不同的playerglobal.swc，flash player 11.3对应的playerglobal.swc见附件。下载解压后，将playerglobal.swc放到SDK目录下frameworkslibsplayer11.3文件夹中。

2.重新编译Flex项目或关闭项目后重新打开，错误解除。

3.测试代码如下：

<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009" 
			   xmlns:s="library://ns.adobe.com/flex/spark" 
			   xmlns:mx="library://ns.adobe.com/flex/mx" 
			   minWidth="955" minHeight="600"
			   applicationComplete="applicationCompleteHandler(event)">
	<fx:Script>
		<![CDATA[
			import mx.controls.Alert;
			import mx.controls.Menu;
			import mx.events.FlexEvent;
			import mx.events.MenuEvent;
			
			protected function applicationCompleteHandler(event:FlexEvent):void{
				this.addEventListener(MouseEvent.RIGHT_CLICK,rightClickHandler);
			}
			private var myMenu:Menu = null ;
			protected function rightClickHandler(event:MouseEvent):void{
				//定义了一个menu 
				if(myMenu==null){
					var menuData:Array = [ 
						{label: "菜单1"},{label: "菜单2"},{label: "菜单3"}
					];
					myMenu = Menu.createMenu(this,menuData,false);
					myMenu.labelField = "label" ;
					myMenu.addEventListener(MenuEvent.ITEM_CLICK,menuItemClickHandler);
					myMenu.addEventListener(MouseEvent.ROLL_OUT,menuRollOutHandler);
				}
				//隐藏掉上一个右键菜单
				myMenu.hide() ;
				myMenu.show(event.stageX,event.stageY);
			}
			
			protected function menuItemClickHandler(event:MenuEvent):void{
				Alert.show(String(event.item.label),"点击");
			}
			/**
			 * 鼠标移出后隐藏右键菜单
			 */
			protected function menuRollOutHandler(event:MouseEvent):void{
				myMenu.hide() ;
			}
			
		]]>
	</fx:Script>
	<fx:Declarations>
		<!-- 将非可视元素（例如服务、值对象）放在此处 -->
	</fx:Declarations>
	<s:Label text="测试"/>
</s:Application>

?效果如下：
