使主窗口位于PySide的顶部

场景:

所以基本上我有3个不同的窗口和1个windows管理器文件。windows管理器启动其中一个窗口(主窗口),从中可以打开其他窗口。到现在为止,一直都还不错。但是,新窗口是 总是在最上面 在主窗口。
如果我们打开所有窗口并单击 test1 或 test2 “总是在最上面”的焦点切换,我们在我们点击的那个焦点上,所以我们可以很容易地阅读每个焦点上的文本。

问题是:

这种行为不会发生在 main 窗户。不管怎样,主窗口总是在后面,如果其他窗口打开了,你就不能把 主要的 把它开到前面。

我想把它带到前线,所以我一直在尝试不同的方法。windows管理器上的commented函数是我尝试过的一些事情的列表。

笔记:

我在Windows 10上使用Python 3.7、PySide2和Qt5.11。

如果我没记错的话,这也会发生在PyQt5上。

这只是最小的例子,在我的生产代码中,我们有40个窗口,比主菜单大600%,如果我们想从中打开一个新窗口,我们必须将当前窗口移到“查找”菜单的位置。

我一直在读这样的限制可能来自windows本身,但是,如果没有什么可以做的话,我现在需要一些建议。

• 如何创建基于多窗口的应用程序,使打开的窗口不隐藏主菜单?

我是一个自学成才的程序员,这是我第一次为一个GUI编写windows管理器,所以请随意提出一种不同的方法来构建windows管理器。

为什么? _raise() 这窗户不好用吗?
怎样才能得到同样的结果?
