gxt - GXT 方法覆盖问题

Question

使用 GXT 我想覆盖 GXT 示例网页上“拖放网格”示例中的“拖放”。

有人知道我应该重写的方法吗？API 如此庞大和冗长，几乎不可能在这个混乱中找到任何东西！

Answer 1

To set a grid to do drag and drop is simply adding it as a Drag source as below

GridDragSource gridDragSource = new GridDragSource(yourGrid);

You then can add your own listener to handle drag

gridDragSource.addDNDListener(new DNDListener() {
   public void dragMove(DNDEvent e) {
  }

  public void dragStart(DNDEvent e) {
  }

  public void dragEnter(DNDEvent e) {
  }

  public void dragLeave(DNDEvent e) {
  }

  public void dragDrop(DNDEvent e) {
  }

}
