推荐答案
这是一个计算器吗？
请使用Gridlayout - 当你调整窗口大小时，Flowlayout会改变。
布局管理器的可视指南 [ ^ ] @ oracle.com
我还建议OOP返回按钮的代码 - 创建一个将标签文本作为参数传递的函数。更好，更短。
Is that a calculator?
Please use Gridlayout for that - the Flowlayout will change when you resize the Window.
A Visual Guide to Layout Managers[^] @ oracle.com
I'd also recommend to OOP the returning code for the buttons - make a function that you pass the label text as an argument. Much better, much shorter.
