PyQt:使用hide和sh后取消堆叠按钮

Question

我有一个分组框，我有垂直排列的按钮。见下图。红色背景表示我的堆叠小部件的哪个索引是活动的，忽略它就行了。你知道吗

按钮排列

当我使用.hide（）方法时，按钮隐藏了，太好了。你知道吗

但是，当我在按钮上使用.show（）方法时，它不会返回。我假设它被放在另一个按钮下，我无法访问该按钮。见下图。你知道吗

破损按钮排列

我试过在组框上使用.adjustSize（）、.repaint（）和.update（）方法，但是没有解决这个问题。你知道吗

我应该在分组框中提到，我确实有一个垂直间隔符，它有一个“扩展”的大小类型，可以向上推动按钮。你知道吗

问题： 当我使用.show（）方法时，如何让按钮作为第一个图像再次显示和展开？你知道吗

根据请求，添加示例代码。请记住这是我能做到的最小限度。你知道吗

Answer 1

我发现了问题所在。显示btn的if语句被忽略，因为它是在json将数据转储回文件之后。你知道吗
