gxt網格中的條件編輯

Question

我有一個可編輯的gxt樹網格，現在問題是隻有某些行必須是可編輯的。一些護目鏡後，我能找到這個東西。我正在使用內嵌編輯器

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 

      } 
     }); 

有沒有辦法實現這一目標？

Answer 1

可以通過選擇模型

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); 



       } 
      });
