Flex List 多列

Flex 4：

<s:List dataProvider="{chResult}"  width="222" height="204" x="271" y="280">
        <s:layout>
            <s:TileLayout requestedColumnCount="3" /><!--多列-->
        </s:layout>
        <s:itemRenderer>
            <fx:Component>
                <mx:HBox verticalAlign="middle" horizontalAlign="left">
                    <fx:Script>
                        <![CDATA[
                            import mx.controls.Alert;
                            protected function changeHandler():void{
                                data.BZ=!data.BZ; //改变选择状态
                                outerDocument.changeXZCS();//改变选择数目
                            }
                        ]]>
                    </fx:Script>
                    <mx:CheckBox label="{data.CH}" selected="{data.BZ}" change="changeHandler()">
                    </mx:CheckBox>
                </mx:HBox>
            </fx:Component>
        </s:itemRenderer>
    </s:List>

Flex 3 中：

<mx:TileList columnCount="3">
<mx:TextInput />
......
</mx:TileList>
