Flex动态生成可编辑的DataGrid具体实现代码

package datagridview
{
import .adobe.serialization.json.JSON;
import .jzh.test.ComboxColumn;
import .jzh.test.ComboxItem;
import mx.collections.ArrayCollection;
import mx.controls.Alert;
import mx.controls.ComboBase;
import mx.controls.ComboBox;
import mx.controls.DateField;
import mx.controls.RadioButtonGroup;
import mx.controls.advancedDataGridClasses.AdvancedDataGridColumn;
import mx.core.ClassFactory;
import mx.validators.RegExpValidator;
import spark.ponents.DropDownList;
public class RendererUtil
{
public function RendererUtil()
{
}
public static function getButtonRenderer():ClassFactory{
var f:ClassFactory=new ClassFactory(OperateButtons);
f.properties={};
return f;
}
public static function getNumRenderer():ClassFactory{
var f:ClassFactory=new ClassFactory(numLabel);
f.properties={};
return f;
}
public static function getComboxRenderer(arr:ArrayCollection,label:String):ClassFactory{
//应该在这里查询数据库
var f:ClassFactory=new ClassFactory(ComboBox);
f.properties={dataProvider: arr,labelField:label,selectedIndex:'0',selectedItem:'石质路面'};//添加属性,绑定选择状态
return f;
}
public static function getRadioRenderer(label:String):ClassFactory{
var f:ClassFactory=new ClassFactory(ComboBox);
var arr:ArrayCollection=new ArrayCollection();
arr.addItem("是");
arr.addItem("否");
f.properties={dataProvider: arr,labelField:label,selectedIndex:'0',selectedItem:'否'};//添加属性,绑定选择状态
return f;
}
public static function getDateRenderer():ClassFactory{
var f:ClassFactory=new ClassFactory(DateField);
f.properties={formatString:"YYYY-MM-DD",showToday:true};//添加属性,绑定选择状态
return f;
}
/本来想在这渲染生成验证器的，无奈技术在达不到/
public static function getValidateRenderer():ClassFactory{
var f:ClassFactory=new ClassFactory(RegExpValidator);
f.properties={ source:"roadcode",
property:"text" ,
expression:"^[0-9]$",
noMatchError:"填写验证不通过时显示他提示信息" };//添加属性,绑定选择状态
return f;
}
/测试用/
public static function getRenderer(label:String,callback:Function=null):ClassFactory{
var f:ClassFactory=new ClassFactory(numLabel);
f.properties={lab:label,callback:callback};
return f;
}
}
}
