Flex 的DataGrid列 的字体，根据不同情况 渲染不同颜色

通过LabelFunction:

 

<mx:DataGridColumn headerText="批复明细" dataField="isReply" width="90"

									   labelFunction="{function(item:Object,col:Object):String

									   {

									   if(item.isReply==1)

									   {return '已批';}

									   else 

									   {return '未批';}

									   

									   }

									   }">

						<mx:itemRenderer>

							<fx:Component>

								<mx:Label >

									<fx:Script>

										<![CDATA[

											import mx.controls.DataGrid;     

											import mx.controls.dataGridClasses.DataGridColumn;     

											import mx.controls.listClasses.BaseListData;  

											override public function set data(value:Object):void    

											{     

												super.data = value;     

												var dg:DataGrid = this.owner as DataGrid;     

												if(dg && data){     

													var dgc:DataGridColumn =     

														dg.columns[listData.columnIndex] as DataGridColumn;     

													//获得 lablFuncton 返回的结果  

													var nowCellText:String=dgc.itemToLabel(value);  

													if(nowCellText.indexOf("已批")==-1){  

														this.setStyle("color","red");     

													}else{  

														this.setStyle("color","black");      

													}  

												}     

											}    

											

										]]>

									</fx:Script>

								</mx:Label>

							</fx:Component>

						</mx:itemRenderer>

					</mx:DataGridColumn>

 

通过DataField: (仅仅是函数不同)

 

  override public function set data(value:Object):void    

        {     

            super.data = value;     

            var dg:DataGrid = this.owner as DataGrid;     

            if(dg && data){     

                var dgc:DataGridColumn =     

                    dg.columns[listData.columnIndex] as DataGridColumn;     

        //根据 dataField不同情况 配色  

                if(data[dgc.dataField]== "0"){     

                    this.setStyle("color",0x7F7F7F);     

                }     

                else if(data[dgc.dataField]=="1"){     

                    this.setStyle("color","black");     

                } else if (data[dgc.dataField]=="2") {  

                    this.setStyle("color",0xCD0000);     

                }else if(data[dgc.dataField]=="3"){  

                    this.setStyle("color",0x008000);     

                }  

            }     

        }
