第一步：到http://rightclickmanager.googlecode.com/下载rightclickmanager-source-lib-0.1.rar并引入自己的FLEX工程，这是实现右键点击事件，及完全屏闭系统右键菜单的关键！（将src目录下的com复制到自己的Flex工程中即可，mx不用复制到自己的工程中）
第二步：
修改RightClickManager.as文件的
static private var rightClickTarget:*;
再修改两个该文件的两个函数：
static private function mouseOverHandler(event:MouseEvent) : void
{
rightClickTarget = InteractiveObject(event.target);
return;
}
static private function dispatchRightClickEvent() : void
{
var event:ContextMenuEvent;
if (rightClickTarget != null)
{
event = new ContextMenuEvent(RIGHT_CLICK, true, false, rightClickTarget as InteractiveObject, rightClickTarget as InteractiveObject);
rightClickTarget.dispatchEvent(event);
}// end if
return;
}
修改RightClickManager的事件从MouseEvent改为ContextMenuEvent是为了能在列表控件DataGrid\Tree\List上点右键时自动选择当前行，使用了ContextMenuEvent事件中的 event.mouseTarget和列表控件的IListItemRenderer接口！
第三步：打开自己的Flex工程下的html-template文件夹下的index.template.html文件（右击-Open With-Text Editor），在var params = {};语句的下面添加下面的语句：
params.wmode = "opaque";//屏蔽系统右键菜单的关键
第四步：在主程序文件中引入：
（注：写在
<fx:Script>
<![CDATA[
]]>
</fx:Script>
的里面）
import com.siloon.plugin.rightClick.RightClickManager;
[Event(name="rightClick",type="flash.events.ContextMenuEvent")]
//右键菜单的图标
[Embed("images/menu_SP_add.png")]
private var menu_SP_add:Class;
[Embed("images/menu_TZ_add.png")]
private var menu_TZ_add:Class;
[Embed("images/menu_Folder_add.png")]
private var menu_Folder_add:Class;
[Embed("images/menu_FJ_uploadsingle.png")]
private var menu_FJ_uploadsingle:Class;
……
protected var rightClickRegisted:Boolean = false;
private var menu:Menu;
第五步：
在init函数中加入如下语句：
（注：init函数即程序的初始化函数
<mx: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"
creationComplete="init();" layout="absolute"
minWidth="1000" minHeight="650" xmlns:local="*">
）
if (!rightClickRegisted)
{
RightClickManager.regist();
rightClickRegisted = true;
}
tree.addEventListener(RightClickManager.RIGHT_CLICK,treeRightClickHandler);
再添加如下函数：
//mx:Tree控件右击事件
private function treeRightClickHandler(event:ContextMenuEvent):void
{
tree_onRightClicked(event);
tree_removeMenu();
tree_InitMenu();
}
//mx:Tree控件右击自动选择
private function tree_onRightClicked(e:ContextMenuEvent):void
{
var rightClickItemRender:IListItemRenderer;
var rightClickIndex:int;
if(e.mouseTarget is IListItemRenderer)
{
rightClickItemRender = IListItemRenderer(e.mouseTarget); }
else if(e.mouseTarget.parent is IListItemRenderer)
{
rightClickItemRender = IListItemRenderer(e.mouseTarget.parent);
}
if(rightClickItemRender != null)
{
rightClickIndex = tree.itemRendererToIndex(rightClickItemRender);
if(tree.selectedIndex != rightClickIndex)
{
tree.selectedIndex = rightClickIndex;
}
}
}
//删除右键菜单
private function tree_removeMenu():void
{
if(menu!=null)
{
menu.hide();
menu.removeEventListener(MenuEvent.ITEM_CLICK,tree_MenuItemSelected);
menu=null;
}
}
//生成右键菜单
private function tree_InitMenu():void
{
menu = Menu.createMenu(this, tree_createMenuItems(), false);
menu.iconField="itemIcon";//右键菜单的图标
menu.labelField="label"; //右键菜单的名称
menu.variableRowHeight = true;
menu.addEventListener(MenuEvent.ITEM_CLICK, tree_MenuItemSelected); //右键菜单的事件
var point:Point = new Point(mouseX,mouseY);
point = localToGlobal(point);
menu.show(point.x,point.y); //显示右键菜单
}
//生成菜单项，菜单项是根据右击时自动选择的树的节点的深度和属性动态生成的，所选择的树的节点的深度和属性不同则生成的菜单项不同。（GetRootNode是获取根节点的函数，FascRightMenu等函数用于生成对应的菜单项）
private function tree_createMenuItems():Array
{
var menuItems:Array = new Array();
var menuItem:Object;
menuItem = new Object;
menuItem.label = '刷新'; //菜单项名称
menuItem.itemIcon = this.menu_SX;//菜单项图标
menuItems.push(menuItem);
var currentItem:XML=tree.selectedItem as XML;
var depth:Number=GetDepth(currentItem);
if(depth==0)
{
if(GetRootNode(currentItem).attribute("tag").toString()=="gyfasctz"||GetRootNode(currentItem).attribute("tag").toString()=="myfasctz"||GetRootNode(currentItem).attribute("tag").toString()=="szfasctz")
{
FascRightMenu(menuItems);//生成对应菜单项
}
else
{
LctypeRightMenu(menuItems);
}
}
if(depth==1)
{
……
}
……
return menuItems;
}
//生成具体菜单项
private function FascRightMenu(menuItems:Array):void
{
var menuItem:Object = new Object;
menuItem.label = "添加台账"; //菜单项名称
menuItem.itemIcon = this.menu_TZ_add;//菜单项图标
menuItems.push(menuItem);
}
//菜单项点击事件
private function tree_MenuItemSelected(event:MenuEvent):void
{
var menuItem:Object = event.menu.selectedItem as Object;
……
switch(menuItem.label)
{
case "刷新":
……
break;
……
}
