我的一个选项卡的结构QTabWidget如下所示：
小部件的其余选项卡已经响应，所以我想让这个也响应。如果它可以在长度上伸展，那么就没有什么可以在高度上伸展了。
因此，我决定在调整表单大小时可以简单地缩放所有元素，并且我已经问过这个问题，但之后我有新问题：
添加任何
styleSheet（甚至是空的，例如QLineEdit { }）时，代码self.setFont(...)也不起作用self.font.setPointSize(...)。是否可以将除文本之外的所有元素缩放
QTabWidget？关于如何正确确保这些选项卡上的响应性，还有其他选择吗？

如果您删除.ui文件，此代码将起作用styleSheet "QLineEdit { }"。
试试这样：
