我想添加更多的選項卡到標籤面板接收到來自servelet的響應..問題是，它只增加了最後一個，而不是其他人看到下面的代碼的一部分。現在看來似乎只是把最後面板「時代的報告」，而不是其他兩個 謝謝嘗試添加更多的選項卡到標籤面板點擊一個按鈕
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;
}
}
