Python 模拟tkinter pack几何体中的上、下、左和右边距

如何使左（青色）和右（品红）边框的垂直高度从上（青色）到下（品红）不等

import Tkinter as tk

root = tk.Tk()

top_margin = tk.Frame(root, height=32, background='red')
left_margin = tk.Frame(root, background='cyan')
sheet_area = tk.Frame(root, background='white')
right_margin = tk.Frame(root, background='magenta')
bottom_margin = tk.Frame(root, height=32, background='blue')

top_margin.pack(side=tk.TOP, expand=tk.YES, fill=tk.X, anchor=tk.N)
bottom_margin.pack(side=tk.BOTTOM, expand=tk.YES, fill=tk.X, anchor=tk.S)
left_margin.pack(side=tk.LEFT, expand=tk.YES, fill=tk.BOTH)
right_margin.pack(side=tk.RIGHT, expand=tk.YES, fill=tk.BOTH)

root.mainloop()

所以我想我知道你的问题是什么。您正在将上下页边距打包到左右页边距之前。不设置任何特定的边距大小

如果您将pack语句更改为如下所示：

left_margin.pack(side=tk.LEFT, expand=tk.YES, fill=tk.BOTH)
right_margin.pack(side=tk.RIGHT, expand=tk.YES, fill=tk.BOTH)
top_margin.pack(side=tk.TOP, expand=tk.YES, fill=tk.X, anchor=tk.N)
bottom_margin.pack(side=tk.BOTTOM, expand=tk.YES, fill=tk.X, anchor=tk.S)

如果希望上下页边距可见，请同时添加宽度。像这样：

bottom_margin = tk.Frame(root, width = 10, height=32, background='blue')
top_margin = tk.Frame(root, width = 10, height=32, background='red')

希望这能解决你的问题：）
