我正在编写一个非常简单的 SmartGWT 应用程序，它在本地使用 100 个元素填充列表网格（不涉及 RPC 或任何服务器交互）。

当我滚动列表网格时，滚动速度明显变慢

环境：SmartGWT 3.0 GWT 2.4.0

代码如下：

public class RemoteFileBrowser implements EntryPoint {

// /**
// * The message displayed to the user when the server cannot be reached or
// * returns an error.
// */
// private static final String SERVER_ERROR = "An error occurred while "
// + "attempting to contact the server. Please check your network "
// + "connection and try again.";
//
// /**
// * Create a remote service proxy to talk to the server-side Greeting
// service.
// */
// private final RemoteFileServiceAsync greetingService = GWT
// .create(RemoteFileService.class);

/**
 * This is the entry point method.
 */
public void onModuleLoad() {
////            SC.say("Welcome to remote file browser!");
//      RemoteFileDialog rfDialog = new RemoteFileDialog("*.*, *.htm, *.cpp, *.hpp");
//      rfDialog.show();
        getListView().draw();

    }

    private ListGrid getListView() {

        ListGrid grid = new ListGrid();
        grid.setWidth(500);
        grid.setHeight(400);
        grid.setLeft(100);
        grid.setTop(100);

        ListGridField field1 = new ListGridField("name");
        ListGridField field2 = new ListGridField("designation");
        grid.setFields(field1, field2);

        ListGridRecord[] records = new ListGridRecord[100];
        for (int i=0; i<100; ++i) {
            //ListGridRecord record = new ListGridRecord();
            records[i] = new ListGridRecord();
            GWT.log("Iteraton:" + i);
            records[i].setAttribute("name", "name" + i);
            records[i].setAttribute("designation", "designation" + i);
        }
        grid.setData(records);
        return grid;
    }

}

展示示例似乎工作正常。当我在本地填充列表网格而不设置数据源时，就会出现问题。

任何想法，我在哪里弄错了？

提前感谢您的帮助。

问候，房车
