python - 如何使 python tkinter 小部件出现在框架的右侧并向左增长？

Question

当前行为，将 LabelFrame 小部件（带有自己的标签和图片子项）添加到另一个名为“Test puts buffs...”的 LabelFrame 中。LabelFrame 小部件被添加到 LabelFrame 的左侧并“增长”到右侧。想要的行为是小部件出现在框架的右侧并在左侧“增长”。

似乎无法通过锚定或粘性设置到达那里。这种“向左增长”如何完成，并且仍然保留按名称或剩余时间排序的能力？

试试这个（使用@acw1668 的建议）：

import tkinter as tk
from tkinter import ttk
from PIL import ImageTk, Image
import time

class MainFrame(tk.Frame):
    def __init__(self, container):
        super().__init__(container)

        self.buffs_list_frames = []

if __name__ == "__main__":

    main_frame = MainFrame(app)
    main_frame.pack()
    app.mainloop()

我对您的代码进行了一些更改。最主要的是我删除buffs_display_nicely并添加了buff_frame.pack(side="right"). side="right"告诉tkinter从右到左添加小部件。

如果你添加一个类而不是使用buff_frame.buff_birthday, buff_frame.buff_timer, ，你也可以大大改进你的代码。它也会让你的生活更轻松
