gxt网格中的条件编辑

Question

我有一个可编辑的gxt树网格，现在问题是只有某些行必须是可编辑的。一些护目镜后，我能找到这个东西。我正在使用内嵌编辑器

editing.addBeforeStartEditHandler(new BeforeStartEditHandler<RevenueGrossBean>() { 

      @Override 
      public void onBeforeStartEdit(
        BeforeStartEditEvent<RevenueGrossBean> event) { 

                //how to acess the model bean that is about to be edited 
               //hw to prevent the edit action from completion 

      } 
     }); 

有没有办法实现这一目标？

Answer 1

可以通过选择模型

editing.addBeforeStartEditHandler(new BeforeStartEditHandler<RevenueGrossBean>() { 

       @Override 
       public void onBeforeStartEdit(
         BeforeStartEditEvent<RevenueGrossBean> event) { 

      //how to acess the model bean that is about to be edited 
      RevenueGrossBean bean = event.getSource().getEditableGrid() 
         .getSelectionModel().getSelectedItem(); 
      //hw to prevent the edit action from completion 
      event.setCancelled(true); 



       } 
      });
