在到达滚动位置结束时动态添加数据

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

public void handleEvent（GridEvent be）{

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

EditorTreeGrid component = be.getComponent（）;    的System.out.println（be.getScrollTop（））;                         //以上似乎总是如此                         //随着我改变卷轴的速度而改变。

}

请帮忙。  }）;

我使用LiveGrid进行了此操作并对其进行了修改以支持可编辑的网格。
