以ZK处理MouseScroll

Question

我想处理zk中的MOUSE事件滚动，但找不到它。我可以使用JavaScript进行操作，但是我想将通知发送到服务器端，以便服务器可以将数据发送回客户端。有什么办法可以在Controller中获取该事件。或做

comp.addEventListener(EVENTNAME,mylistener);

我想知道上面的EVENTNAME的值是什么。

Answer 2

这是我在分页网格中捕获鼠标滚动以通过鼠标滚轮推进页面的工作；发送通知到服务器端的部分是以下行：this.getPaginal（）。fire（'onPaging'，nextPage）

<zk>
<zscript>Object[] o = new String[150];

</zscript>
<hlayout id="layout" vflex="1" hflex="1">
    <grid id="grid1" width="300px" autopaging="true" height="300px"  mold="paging" vflex="true">
        <rows>
            <row forEach="${o }">
                <label value="item ${forEachStatus.index}"/>
            </row>
        </rows>
    </grid>
</hlayout>
