如何在 tkinter python3 中修复/放置小部件？

Question

在我的以下代码中，在顶层窗口中，我无法正确修复小部件并具有美观的外观。

我收到以下错误。 你能帮我优化一下代码吗？

部分代码：

        msg.pack(fill='x', padx=15, pady=10)

        container.pack(side="left",fill='both', expand=True)

我正在尝试修复/放置小部件并在表单中显示所有小部件。 我希望

form_frame

和小部件能够沿着

add_new_window

调整大小，并保持干净的外观。

在那部分你已经使用了 pack。之后，在 min_val 和 m_val 中，你尝试对它们进行网格化。 Tkinter 不允许在同一帧中使用不同的打包选项。

msg = ttk.Label(wraplength="2i", justify="right", anchor="n",
        padding=(10, 2, 10, 6), text=s , font=('title','10'))
    msg.pack(fill='x', padx=15, pady=10)

因此，对于您的代码，您需要将它们更改为行，并添加框架。

    min_val=tk.Entry().grid(row=11, column=0, pady=5, sticky=('ew'))
    m_val=tk.Entry().grid(row=13, column=0, pady=5, sticky=('ew'))

将该部分更改为。所以，你的问题将会得到解决。

    min_val=tk.Entry(form_frame).grid(row=11, column=0, pady=5, sticky=('ew'))
    m_val=tk.Entry(form_frame).grid(row=13, column=0, pady=5, sticky=('ew'))
