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);     
                }  
            }     
        }
