如何刷新GWT中的TreeGrid?

你好朋友我正在开发一个GWT应用程序,我正在使用TreeGrid。当我在这个矿类中使用常规网格时:

RpcProxy<ListLoadResult<GwtDatastoreAsset>> proxy = new RpcProxy<ListLoadResult<GwtDatastoreAsset>>() {

            @Override
            protected void load(Object loadConfig, AsyncCallback<ListLoadResult<GwtDatastoreAsset>> callback) {
                if (selectedDevice != null) {
                dataService.findAssets((LoadConfig) loadConfig, currentSession.getSelectedAccount().getId(), selectedDevice, callback);
                }
            }
        };

        loader = new BaseListLoader<ListLoadResult<GwtDatastoreAsset>>(proxy);
        loader.load();
        SwappableListStore<GwtDatastoreAsset> store = new SwappableListStore<GwtDatastoreAsset>(loader);
        assetGrid = new Grid<GwtDatastoreAsset>(store, new ColumnModel(configs));
        assetGrid.setBorders(false);
        assetGrid.setStateful(false);
        assetGrid.setLoadMask(true);
        assetGrid.setStripeRows(true);
        assetGrid.getView().setAutoFill(true);
        assetGrid.getView().setEmptyText(MSGS.assetTableEmptyText());
        assetGrid.disableTextSelection(false);

在我的刷新方法的这个类中,我只做了assetGrid.getStore()。getLoader()。load(); 就是这样,但是对于TreeGrid,我不能这样做。这是我使用TreeGrid的方法:

 AsyncCallback<List<GwtTopic>> topicsCallback = new AsyncCallback<List<GwtTopic>>() {

            @Override
            public void onSuccess(List<GwtTopic> topics) {
                store.add(topics, true);
                topicInfoGrid.unmask();
            }

            @Override
            public void onFailure(Throwable t) {
                FailureHandler.handle(t);
                topicInfoGrid.unmask();
            }
        };
        dataService.findTopicsTree(currentSession.getSelectedAccount().getId(), topicsCallback);
        topicInfoGrid = new TreeGrid<GwtTopic>(store, new ColumnModel(configs));
        topicInfoGrid.setBorders(false);
        topicInfoGrid.setStateful(false);
        topicInfoGrid.setLoadMask(true);
        topicInfoGrid.mask("Loading");
        topicInfoGrid.setStripeRows(true);
        topicInfoGrid.getView().setAutoFill(true);
        topicInfoGrid.getView().setEmptyText(MSGS.topicInfoGridEmptyText());
        topicInfoGrid.disableTextSelection(false);

所以我的问题是如何为TreeGrid制作刷新方法,就像我使用常规网格一样。

答案 0 :(得分:0)

答案 1 :(得分:0)

尝试在 onSuccess 方法之后添加:

topicInfoGrid.getTreeView().refresh(true);

或者如果刷新不起作用

 topicInfoGrid.reconfigure(store, cm, treeColumn);
