我有一个 ui 文件，如下所示：

我希望组框显示在整个窗口中（组框文本就在菜单下方。当我在应用程序中构建它并在 qt 设计器预览中查看时，它会在顶部留下一个空间 top_pages 的箭头所在位于。如何使组框扩展到这个空间？我可以打破布局并将其扩展到这个空间，但我认为这需要对stackedWidget_2 的每一页都这样做。

我认为这就是你想要创造的。有几个堆栈小部件。我做了一个。只是为了表明我在堆叠的小部件周围添加了框框。它可以很容易地从属性中删除

我所做的只是遍历所有小部件，并通过在对象编辑器（centralWidget、page、page_3、page_4）中选择它们并在属性编辑器中修改它们的布局属性来将它们的布局的上边距减少到 0。无需打破布局。
