如何在javafx中去掉空间

我正在使用JavaFX SceneBuilder创建FXML。我的窗口只是一个边框窗格：宽度800，高度625。顶部是一个菜单栏：宽度使用大小，高度25。中间是一个锚平面：宽度800，高度600。在它里面，我使用宽度为800，高度为600的ImageView作为背景图像

它完全适用于SceneBuilder，但当我作为Java应用程序运行时，在右边和底部都有空白，如下所示：

请帮助删除它，对不起，我是JavaFx的新手

更新：我已经将它分为2个布局，然后是RootLayout setCenter main布局，但它不起作用

RootLayout.fxml：

如果没有任何代码，很难说哪个组件负责空间。您可以将FXML添加到您的问题中吗？您可以使用来检查场景。正如ItachiUchiha提到的，我们只能在没有代码的情况下猜测。对不起，伙计们，我添加了fxml代码above@Việ德克萨斯州ấuTính样式类ruleButton中有什么？@ItachiUchiha-fx focus traversable:true；
