昨天研究了UILloader组件放入datagrid中，今天把checkbox放进去，这才是我要的重点，呵呵，终于有成果了，也不算没白看，进入正题。

准备阶段，要保证datagrid和checkbox组件在fla的库中。

时间轴as如下

         import fl.controls.DataGrid;
import fl.controls.dataGridClasses.DataGridColumn;
import fl.data.DataProvider;

var dp:DataProvider = new DataProvider();

dp.addItem({data:"点击选择", title:"image1.jpg"});
dp.addItem({data:"点击选择", title:"image2.jpg"});
dp.addItem({data:"点击选择", title:"image3.jpg"});
dp.addItem({data:"点击选择", title:"Bear.jpg"});
dp.addItem({data:"点击选择", title:"Lion.jpg"})

var dataCol:DataGridColumn = new DataGridColumn("数据");
dataCol.cellRenderer = LoaderCellRenderer;

var titleCol:DataGridColumn = new DataGridColumn("title");


var myDataGrid:DataGrid = new DataGrid();
myDataGrid.addColumn(dataCol);
myDataGrid.addColumn(titleCol);
myDataGrid.dataProvider = dp;
myDataGrid.rowHeight = 64;
myDataGrid.width = 200;
myDataGrid.rowCount = dp.length - 1;
myDataGrid.move(10, 10);
addChild(myDataGrid);

下面是LoaderCellRenderer.as类

          package {
//导入所需要的类
    import fl.controls.listClasses.ICellRenderer;
    import fl.controls.listClasses.ListData;
    import fl.core.InvalidationType;
    import fl.data.DataProvider;
    import flash.events.Event;
	import fl.controls.CheckBox;
//LoaderCellRenderer  实现  ICellRenderer  接口
public class LoaderCellRenderer extends CheckBox implements ICellRenderer {
        protected var _data:Object;
        protected var _listData:ListData;
        protected var _mySelected:Boolean;
    
        public function LoaderCellRenderer():void {
            super();
        }

        public function get data():Object {
            return _data;
        }
        public function set data(value:Object):void {
            _data = value;
            //checkbox的文字
            label = value.data;
        }

        public function get listData():ListData {
            return _listData;
        }
        public function set listData(value:ListData):void {
            _listData = value;
            invalidate(InvalidationType.DATA);
            invalidate(InvalidationType.STATE);
        }

        public function get  select():Boolean {
            return _mySelected;
        }
        public function set  select(value:Boolean) :void {
            _mySelected = value;
            invalidate(InvalidationType.STATE);
        }
      	 public function setMouseStates(state:String):void {
			 
        }
    }
}
