Actionscript 3 选项卡在mx:TileList组件中不起作用

我使用mx:Tilelist组件在屏幕上显示一组文本字段，但当我试图通过TAB-foucs遍历字段时，会将其移出列表。请提供此问题的解决方案。下面是我正在使用的代码

    <mx:TileList id="tileList"
            dataProvider="{collection}"
            change="setCurrentIndex(tileList.selectedIndex);"
            dataChange="setCurrentIndex(tileList.selectedIndex);"
            columnCount="1"
            columnWidth="345"
            itemRenderer="components.InputParamIR"
            rowHeight="30"
            verticalScrollPolicy="auto"
            horizontalScrollPolicy="auto"
            backgroundColor="#EEEEEE"
            dragEnabled="false"
            dragMoveEnabled="true"
            dropEnabled="true"
            width="100%" height="100%"
            itemClick="chartTileClick(event);" 
            />


<fx:Script>
    <![CDATA[
        import mx.collections.ArrayCollection;
        import mx.containers.Panel;

        [Bindable]
        public var index:uint;
        [Bindable]
        public var collection:ArrayCollection = new ArrayCollection(); 
        [Bindable]
        public var isVisible:Boolean ;

        public  function initEventsLocal(event:Event):void
            {
             this.initEvents(event);
             collection = new ArrayCollection(); 
             isVisible = false;

            }   

        private function chartTileClick(event:ListEvent):void
        {

            event.currentTarget.tabFocusEnabled=true;
            event.currentTarget.tabEnabled=true;

        } 

    ]]>
</fx:Script>

在Flex List Itemrenderer中可能无法获得焦点，因为它是不可编辑的，并且不会实现焦点管理器界面，您需要在项目渲染器组件中实现IfocusManager组件。InputParamIR还必须覆盖TileList类以启用子级选项卡

package  
{  
    import mx.controls.TileList;  

        public class MyTileList extends TileList  
        {  

            override protected function createChildren():void {  
              super.createChildren();  
              this.listContent.tabChildren = this.tabChildren  
              this.listContent.tabEnabled = this.tabEnabled  
            }  
        }  
}    

看看这些

我希望这对你有帮助
