Question

我想在收到来自服务器的响应时向标签面板添加更多标签..问题是它只添加最后一个，而不是其他人看到下面代码的一部分。它似乎只是添加了最后一个面板“时间报告”而不是其他两个谢谢

        btnLogin.addClickListener(new ClickListener() {
            public void onClick(Widget sender) {
                if(getLoginResult())
                                   {
                            HorizontalPanel temp = new HorizontalPanel();
             panel.add(temp, "Add Hours");
             panel.add(temp, "Time Sheets");
             panel.add(temp, "Time Reports");

                                    }

            }

        });

        RootPanel.get().add(panel);
      }

    private boolean getLoginResult() {
        AsyncCallback callback = new AsyncCallback() {
            public void onSuccess(Object result) {

                isAuthenticated = true;

            }

            public void onFailure(Throwable caught) {
                Window.alert("Error when invoking the pageable data service :" + caught.getMessage());
                isAuthenticated = false;
            }
        };

        timesheetLoginServlet.isAuthenticated("1","rapidjava", callback);
        return isAuthenticated;

    }
}

您只能将任何窗口小部件添加到其父窗口一次。将temp更改为temp1，temp2和temp3

单击按钮时，尝试将更多选项卡添加到选项卡面板
