Flex dataGrid使用ItemRenderer在datagridcolumn中添加按钮？

您可以像这样使用inline itemRenderer：

<fx:Script>
  public function myButton_clickHandler(event:Event):void
  {
    Alert.show("My button was clicked!");
  }
</fx:Script>

<mx:DataGrid width="100%" height="95%" id="id_variableRefList" >
  <mx:columns>
    <mx:DataGridColumn id="id_name" dataField=""/>
    <mx:DataGridColumn id="id_strip" dataField="">
      <mx:itemRenderer>
       <fx:Component>
        <mx:VBox>
         <mx:Button label="My Button" click="outerDocument.myButton_clickHandler(event);" />
        </mx:VBox>
       </fx:Component>
      </mx:itemRenderer>
    </mx:DataGridColumn>
  </mx:columns>
</mx:DataGrid>

或者您可以创建DataGridColumn的custom component and set the itemRenderer property.

<mx:DataGrid width="100%" height="95%" id="id_variableRefList" >
  <mx:columns>
    <mx:DataGridColumn id="id_name" dataField=""/>
    <mx:DataGridColumn id="id_strip" dataField="" itemRenderer="MyCustomItemRenderer"/>
  </mx:columns>
</mx:DataGrid>

更新：
要获取单击的按钮的id,可以使用传递给eventListener的事件的currentTarget属性.

public function myButton_clickHandler(event:Event):void
  {
    Alert.show("Button " + Button(event.currentTarget).id + " was clicked!");
  }
