场景：
所以基本上我有3个不同的Windows和1个Windows管理器文件。 Windows管理器启动其中一个窗口（主窗口），然后您可以打开其他窗口。到目前为止，一切都很好。但是，新窗口始终位于主窗口的顶部。
我们可以检查一下是否打开所有窗口，然后单击test1或test2“始终在顶部”焦点开关，并在单击的位置位于顶部，因此我们可以轻松阅读文本在每个人身上。
问题：
main窗口不会发生此行为。无论如何，主窗口始终在后面，如果其他窗口打开，则无法将main窗口放在前面。
我想把它放在前面，所以我一直在尝试不同的方法。 Windows Manager上的注释功能是我尝试过的一些事情的列表。
注释：
我在Windows 10上使用Python 3.7，PySide2和Qt5.11。
如果我没记错的话，这在PyQt5上也会发生。
这只是最小的示例，在我的生产代码中，我们有40个窗口，它们比主菜单大600％，如果要从中打开新窗口，则必须将当前窗口移到“查找”菜单在哪里。
我一直在阅读这种限制，可能来自Windows本身，但是，此时，如果无事可做，我需要建议。
我是一名自学成才的程序员，这是我第一次为GUI编写Windows管理器，因此请随意提出一种不同的方式来构建Windows管理器。

问题：
为什么_raise()在此窗口上不起作用？
如何获得相同的结果？
答案 0 :(得分：0)
在没有父母的情况下创建测试窗口解决了这个问题。
QtWidgets.QMainWindow.__init__(self)
