FLEX 屏闭系统右键菜单，及在列表控件DataGrid/Tree/List上点右键时自动选择当前行

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！

第二步：打开: <主程序名>.template.html 文件，修改为：

 

<!--
    AC_FL_RunContent(
            "src", "${swf}",
            "id", "${application}",
            "name", "${application}",
            "width", "${width}",
            "height", "${height}",
            "align", "middle",
            "menu", "false",
            "wmode", "opaque",                  //注意:这里是右键屏蔽的关键
            "quality", "high",
            "bgcolor", "${bgcolor}",
            "allowScriptAccess", "always",
            "allowNetworking", "all",
            "allowFullScreen", "true",          //是否可全屏的参数
            "type", "application/x-shockwave-flash",
            "pluginspage", "http://www.adobe.com/go/getflashplayer"
    );
//-->

<!--
	AC_FL_RunContent(
			"src", "${swf}",
			"id", "${application}",
			"name", "${application}",
			"width", "${width}",
			"height", "${height}",
			"align", "middle",
			"menu", "false",
			"wmode", "opaque",					//注意:这里是右键屏蔽的关键
			"quality", "high",
			"bgcolor", "${bgcolor}",
			"allowScriptAccess", "always",
			"allowNetworking", "all",
			"allowFullScreen", "true",			//是否可全屏的参数
			"type", "application/x-shockwave-flash",
			"pluginspage", "http://www.adobe.com/go/getflashplayer"
	);
//-->

 

第三步：在主程序文件.as中引入：

    import com.siloon.plugin.rightClick.RightClickManager;

 

并加如下代码：

[Event(name="rightClick",type="fla sh.events.ContextMenuEvent")]
public class index
{

 protected var rightClickRegisted:Boolean = false;

 public function index()
 {
  super();

  if (!rightClickRegisted)
  {
   RightClickManager.regist();
   rightClickRegisted = true;
  }
  try
  {
   name = NameUtil.createUniqueName(this);
  }
  catch (e:Error)
  {
  }
  return;

 }

 public override function toString() : String
 {
  return NameUtil.displayObjectToString(this);
 }

 [Event(name="rightClick",type="fla sh.events.ContextMenuEvent")]
 public class index
 {

  protected var rightClickRegisted:Boolean = false;

  public function index()
  {
   super();

   if (!rightClickRegisted)
   {
    RightClickManager.regist();
    rightClickRegisted = true;
   }
   try
   {
    name = NameUtil.createUniqueName(this);
   }
   catch (e:Error)
   {
   }
   return;

  }

  public override function toString() : String
  {
   return NameUtil.displayObjectToString(this);
  }

 

 

第四步：在要弹出右键的控件的初始化代码中加入：

 

NavTabTree.addEventListener(RightClickManager.RIGHT_CLICK,rightClickHandler);

 

再加以下函数来处理：

 

 

/**
 * 在控制上单击右键菜单事件的处理函数
 * @param event 右键事件
 *
 */
protected function rightClickHandler(event:ContextMenuEvent):void
{
    onRightClicked(event);
    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);
}
/**
 * 如果显示过Menu，则先释放资源
 *
 */
private function removeMenu():void
{
    if(menu!=null)
    {
        menu.hide();
        //menu.removeEventListener(MenuEvent.ITEM_CLICK,menuItemClickHandler);
        menu=null;
    }
}
/**
 * 创建右键菜单选项
 * @return 返回选项组成的Array
 *
 */
private function createMenuItems():Array
{
    var menuItems:Array = new Array();
    var menuItem:Object;

    menuItem = new Object;
    menuItem.label = '清空画布';
    menuItem.action = 'clearAll';
    menuItems.push(menuItem);

    menuItem = new Object;
    menuItem.label = '选择背景';
    menuItem.action = 'selectBackImage';
    menuItems.push(menuItem);

    return menuItems;
}
/**
 * 当右键单击Tree的Item时，自动选择鼠标所在的当前项
 * @param e 自定义右键菜单事件
 *
 */
private function 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 = NavTabTree.itemRendererToIndex(rightClickItemRender);

        if(NavTabTree.selectedIndex != rightClickIndex) {

            NavTabTree.selectedIndex = rightClickIndex;

        }

    }
}

		/**
		 * 在控制上单击右键菜单事件的处理函数
		 * @param event 右键事件
		 * 
		 */		
		protected function rightClickHandler(event:ContextMenuEvent):void
		{
			onRightClicked(event);
			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); 
		}
		/**
		 * 如果显示过Menu，则先释放资源
		 * 
		 */		
		private function removeMenu():void
		{
			if(menu!=null)
			{
				menu.hide();
				//menu.removeEventListener(MenuEvent.ITEM_CLICK,menuItemClickHandler);
				menu=null;
			}
		}
		/**
		 * 创建右键菜单选项
		 * @return 返回选项组成的Array
		 * 
		 */		
		private function createMenuItems():Array
		{
			var menuItems:Array = new Array();
			var menuItem:Object; 

			menuItem = new Object;
			menuItem.label = '清空画布';
			menuItem.action = 'clearAll';
			menuItems.push(menuItem); 

			menuItem = new Object;
			menuItem.label = '选择背景';
			menuItem.action = 'selectBackImage';
			menuItems.push(menuItem); 

			return menuItems;
		}
		/**
		 * 当右键单击Tree的Item时，自动选择鼠标所在的当前项
		 * @param e 自定义右键菜单事件
		 * 
		 */
		private function 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 = NavTabTree.itemRendererToIndex(rightClickItemRender);  

				if(NavTabTree.selectedIndex != rightClickIndex) {  

					NavTabTree.selectedIndex = rightClickIndex; 

				} 

			}  
		}

 

 

第五步：

 

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;
     }

        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;
        }

 

 

        到这里，功能就完成了，本人修改了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！

 

        本功能也有副作用，系统右键菜单失效，那文本的右键复制粘贴也就失效了，有大量用到TEXTINPUT的就要小心使用了~！
