下面是一段小Demo ，实现了数据从【容器1】（控件为List）拖入【容器2】（控件为DropDownList） 其中相关属性在FB4中，鼠标移入都有相应的提示，在此不再多说，看代码： <?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"> <s:layout> <s:BasicLayout/> </s:layout> <fx:Script> <![CDATA[ import mx.core.DragSource; import mx.events.DragEvent; import mx.managers.DragManager; import mx.controls.Alert; //初始化拖拽目标 protected function drageIt(event:MouseEvent):void { // TODO Auto-generated method stub var dragInit:List = event.currentTarget as List; var dragSource:DragSource = new DragSource(); dragSource.addData(dragInit,"name"); // Alert.show("abc","提示！！"); DragManager.doDrag(dragInit,dragSource,event); } //拖拽移入 protected function dragEnterHandler(event:DragEvent):void{ var dropTarget:DropDownList = event.currentTarget as DropDownList; if(event.dragSource.hasFormat("name")){ DragManager.acceptDragDrop(dropTarget); } } //执行拖拽 protected function dragdropHandler(event:DragEvent){ var name:List = List(event.dragSource.dataForFormat("name")); // Alert.show(name.selectedItem.labelField,"提示！！"); if(null!=name.selectedItem ){ this.objs3.addItem(name.selectedItem.labelField); } } ]]> </fx:Script> <fx:Declarations> <!-- 执行拖拽时要确保所有参与控件的dataProvider是同类型，并且已经初始化！！！！！！！！ --> <s:ArrayList id="objs1" > <fx:Object labelField ="LanDian" /> <fx:Object labelField ="OS"/> <fx:Object labelField ="Micorosoft"/> <fx:Object labelField ="航天器"/> <fx:Object labelField ="流星"/> <fx:Object labelField ="海王星"/> <fx:Object labelField ="ENNA"/> <fx:Object labelField ="PiaoLan"/> <fx:Object labelField ="积雨云"/> <fx:Object labelField ="第六感"/> <fx:Object labelField ="雷雨"/> <fx:Object labelField ="田园风光"/> <fx:Object labelField ="北欧风情"/> <fx:Object labelField ="南极洲"/> <fx:Object labelField ="海洋"/> <fx:Object labelField ="银河"/> </s:ArrayList> <s:ArrayList id="objs2" > </s:ArrayList> <s:ArrayList id="objs3" > </s:ArrayList> </fx:Declarations> <s:Panel horizontalCenter="0" verticalCenter="0" width="316" height="383" title="拖拽演示：数据源--可拖入--容器1--可拖入---容器2"> <s:List x="10" y="30" id="sco" width="103" height="301" dataProvider="{objs1}" dragMoveEnabled="true" labelField="labelField" dragEnabled="true" dropEnabled="true"></s:List> <s:Label x="10" y="10" text="选择拖拽源" width="85" fontSize="13" color="#0C73D3"/> <s:List x="142" y="30" id="op" dataProvider="{objs2}" mouseMove="drageIt(event)" labelField="labelField" height="141" width="107" dragEnabled="true" dropEnabled="true" dragMoveEnabled="true"> </s:List> <s:Label x="145" y="10" text="容器1"/> <s:Label x="145" y="184" text="容器2"/> <s:DropDownList x="145" y="204" dataProvider="{objs3}" labelField="labelField" dragEnter="dragEnterHandler(event)" dragDrop="dragdropHandler(event)" ></s:DropDownList> </s:Panel> </s:Application> 注：FB4 本身许多控件已经集成拖拽属性，只需要开启下即可，如本例中 数据源 拖入 容器1。具体参见API或是FB4中提示 转自： http://blog.163.com/ltzx012@126/blog/static/872430842010523258882/
