在AS3中获取数据网格组件的索引

Question

我遇到了一些问题，试图使用ActionScript 3.0获取当前在flash的datagrid组件上徘徊opon的行的索引。

那么请如何获取AS3中鼠标滚动时datagrid的行索引。

感谢

您使用ListEvent.ITEM_ROLL_OVER事件，而不是一个基本的鼠标

import fl.events.ListEvent; 

var sampleItem1:Object = { Name:"John Alpha", Number:"555-123-0101", Email:"jalpha@fictitious.com" }; 
var sampleItem2:Object = { Name:"Mary Bravo", Number:"555-372-3322", Email:"mbravo@fictitious.com" }; 
var sampleItem3:Object = { Name:"Trevor Gamma", Number:"555-485-1212", Email:"tgamma@fictitious.com" }; 
var sampleItem4:Object = { Name:"Susan Delta", Number:"555-987-3434", Email:"sdelta@fictitious.com" };  

dg.columns = ["Name","Number","Email"]; 
dg.addItem(sampleItem1); 
dg.addItem(sampleItem2); 
dg.addItem(sampleItem3); 
dg.addItem(sampleItem4); 

function gridRollOver(e:ListEvent):void 
{ 
    trace("rowIndex: " + e.rowIndex + " columnIndex: " + e.columnIndex);  
} 
dg.addEventListener(ListEvent.ITEM_ROLL_OVER, gridRollOver);
