本文介绍如何使用Adobe Flash CS5及ActionScript 3.0 (AS3) 创建自定义的上下文菜单。通过具体代码示例展示了如何为树形结构的节点添加“新建”选项，并实现相应的事件处理。


<mx:cavas xmlns:mx="http://www.adobe.com/2006/mxml" width="100%" height="100%"  creationComplete="init();">
private var newBuildMenuItem: ContextMenuItem;

internal function init(): void{
				treeMenu();
			}

private function treeMenu(): void{
				createTreeMenuItem();
				tree.contextMenu = getTreeContxtMenu();
			}

public function createTreeMenuItem(): void{
				newBuildMenuItem = new ContextMenuItem("新建");
				newBuildMenuItem.addEventListener(ContextMenuEvent.MENU_ITEM_SELECT, newBuildHandler);
			}

			private function getTreeContxtMenu(): ContextMenu{
				var contextMenu: ContextMenu = new ContextMenu();
				contextMenu.hideBuiltInItems();
				contextMenu.customItems.push(newBuildMenuItem);
				return contextMenu;
			}
