1.flex4.5以前的写法 例如改变mx:datagrid 的字体颜色

package com.qijinsoft.common{    /**     * 为mx:itemRenderer提供字体色彩改变     *      * */    import mx.controls.Label;    import mx.states.SetStyle;        public class ColorLabel extends Label    {                public function ColorLabel()        {            super();        }                override public function set data(value:Object):void        {            // TODO Auto Generated method stub            super.data = value;            if(value.hasOwnProperty('color')){                this.setStyle('color',0xff00cc);//设置颜色            }        }    }}

var col1 : DataGridColumn = new DataGridColumn;col1.dataField = 'name';col1.headerText = '物品名称';col1.itemRenderer = new ClassFactory(ColorLabel);

2.flex4.5以后 s:datagrid设置字体颜色

package com.qijinsoft.common{    import spark.components.Label;    import spark.components.gridClasses.GridItemRenderer;    import spark.skins.spark.DefaultGridItemRenderer;        /**     * 为spark的itemrender 定义字体的颜色设定     *      * */    public class SColorLabel extends DefaultGridItemRenderer    {                private var _color:uint;                public function SColorLabel()        {            super();        }                public function get color():uint        {            return _color;        }        public function set color(value:uint):void        {            _color = value;        }        override public function set data(value:Object):void        {            // TODO Auto Generated method stub            super.data = value;            this.setStyle('color',color);        }            }}

　　            //初始化表格字段                 var column1:GridColumn = new GridColumn;                column1.dataField = 'name';                column1.headerText = '名称';                column1.width = 200;                var factory : ClassFactory = new ClassFactory(SColorLabel);                factory.properties = {color:Color.blue};//注意这个color属性对应SColorLabel中的color的set/get方法                column1.itemRenderer = factory;
