注意：事實上發(fā)現(xiàn)，mx:Repeater控件在數(shù)據(jù)大的時候性能很差。
但是當(dāng)換成AdvancedDataGrid發(fā)現(xiàn)，鼠標(biāo)在Grid上移動Flex自動為焦點所在行修改css，為屏蔽該效果，自定義如下控件:
ApmAdvancedDataGrid.as

復(fù)制代碼代碼如下:

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

復(fù)制代碼代碼如下:

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：

復(fù)制代碼代碼如下:

<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

復(fù)制代碼代碼如下:

<?xml version="1.0" encoding="utf-8"?>
<mx:Canvas xmlns:mx="http://www.adobe.com/2006/mxml">
    <mx:Script>
        
    </mx:Script>
    <mx:VBox>
        <mx:Label id="lab1" text="◆研究テ主站蜘蛛池模板：新巴尔虎左旗| 永修县| 鸡泽县| 原平市| 含山县| 晋城| 亳州市| 天台县| 稻城县| 麟游县| 长子县| 青神县| 吉木乃县| 阿坝| 吉水县| 咸宁市| 沅陵县| 库尔勒市| 农安县| 牙克石市| 临泽县| 远安县| 土默特左旗| 曲阜市| 宜章县| 五常市| 遂昌县| 宁德市| 仁化县| 汉阴县| 哈巴河县| 张北县| 灌云县| 安达市| 潍坊市| 东乌珠穆沁旗| 运城市| 潮安县| 鄂尔多斯市| 习水县| 托里县|
