在 GUI 中,当文本字体和字体大小发生变化时,文本框会调整大小并隐藏按钮。在我的天真中,我认为文本框将保持相同的大小,并且文本将简单地包装在文本框的约束内。至少 taht 是我想要达到的目标。显然在字体大小或文本框、tkinter 中有一些我不明白的概念 谢谢

可能重复 stackoverflow.com/questions/9833698 ,虽然它处理香草文本,但答案很容易适应。

感谢您的评论。我尝试使用您参考中讨论的方法,但没有成功。正如我所说,我将 frame3.grid_propagate(True) 更改为 frame3.grid_propagate(False) 无济于事。欢迎提出建议。
