我有一个ui文件，如下：

<?xml version="1.0" encoding="UTF-8"?>
<ui version="4.0">

 <widget class="QMainWindow" name="MainWindow">

我希望组合框显示在整个窗口中（组合框文本位于菜单下方。当我在应用程序中构建它并在qt设计器预览中查看时，它在顶部留下了一个空格箭头top_pages的位置。如何让组合框扩展到这个空间？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的每一页执行此操作。

我认为这就是你想要创造的东西。有几个堆栈小部件。我做了一个。只是为了指示我已经在堆叠小部件周围添加了框架。它可以很容易地从属性中删除

这是否会产生您想要实现的布局？

我所做的只是浏览所有小部件，并通过在对象编辑器中选择它们将其布局的上边距缩小为0（centralWidget，page，page_3，{{1} }），并在属性编辑器中修改其布局属性。不需要布局。
