gxt - 到达滚动位置末端时动态添加数据

Question

         To limit the number of records fetched, I plan to add more records when we reach the end of the data in an EditorTreeGrid . I have tried the following code

myTree.addListener(Events.BodyScroll,new Listener() {

     @Override

公共无效句柄事件（GridEvent是）{

                  //I need to check if the scroll has reached the end to the list and 
                    then add more records to the store .

EditorTreeGrid 组件 = be.getComponent(); System.out.println(be.getScrollTop());
//当我改变滚动的速度时，上述内容似乎总是发生变化。

}

请帮忙 。});

我使用 LiveGrid 进行了这项工作，并对其进行了修改以支持可编辑的网格。
