Flex中让鼠标移至AdvancedDataGrid的行上不自动修改显示效果

公司项目中出于性能考虑，把mx:Repeater控件换成了mx:AdvancedDataGrid控件来显示。

注意：事实上发现，mx:Repeater控件在数据大的时候性能很差。

但是当换成AdvancedDataGrid发现，鼠标在Grid上移动Flex自动为焦点所在行修改css，为屏蔽该效果，自定义如下控件:

ApmAdvancedDataGrid.as

package com.nauproject.apm.common.custom { import flash.events.MouseEvent; import mx.controls.AdvancedDataGrid; import mx.core.mx_internal; use namespace mx_internal; public class ApmAdvancedDataGrid extends AdvancedDataGrid { public function ApmAdvancedDataGrid() { super(); } override protected function mouseOverHandler(event:MouseEvent):void { } override protected function mouseDownHandler(event:MouseEvent):void { } } }

ApmAdvancedDataGridColumn.as

package com.nauproject.apm.common.custom { import mx.controls.advancedDataGridClasses.AdvancedDataGridColumn; [DefaultProperty("apmColumn")] public class ApmAdvancedDataGridColumn extends AdvancedDataGridColumn { public function ApmAdvancedDataGridColumn(columnName:String=null) { super(columnName); } } }

用法示例：

<custom:ApmAdvancedDataGrid id="reqResearchSeeds" headerHeight="0" sortableColumns="false" selectionMode="multipleCells" alternatingItemColors="[0xccffcc, 0xfafad2]" variableRowHeight="true" designViewDataType="flat" borderStyle="none" verticalGridLineColor="#FFFFFF" themeColor="#FFFFFF" width="100%" height="100%"> <custom:columns> <custom:ApmAdvancedDataGridColumn headerText="Album" dataField="album" width="50"/> <custom:ApmAdvancedDataGridColumn itemRenderer="com.nauproject.apm.common.custom.LabelTextReqRes"/> </custom:columns> </custom:ApmAdvancedDataGrid>

注意：LabelTextReqRes.mxml
