如果计划将每个框强制设置为统一大小，则最简单的解决方案是使用文本小部件作为容器，因为它具有内置功能包装.

If you plan on forcing each box to be a uniform size, the simplest solution is to use the text widget as the container since it has the built-in ability to wrap.

这是一个可行的示例.单击添加"按钮以添加其他框.调整窗口大小，以查看它们随着窗口的增大和缩小而自动环绕.

Here is a working example. Click on the "add" button to add additional boxes. Resize the window to see that they automatically wrap as the window grows and shrinks.

import Tkinter as tk
import random

class DynamicGrid(tk.Frame):
    def __init__(self, parent, *args, **kwargs):
        tk.Frame.__init__(self, parent, *args, **kwargs)
        self.text = tk.Text(self, wrap="char", borderwidth=0, highlightthickness=0,
                            state="disabled")
        self.text.pack(fill="both", expand=True)
        self.boxes = []

    def add_box(self, color=None):
        bg = color if color else random.choice(("red", "orange", "green", "blue", "violet"))
        box = tk.Frame(self.text, bd=1, relief="sunken", background=bg,
                       width=100, height=100)
        self.boxes.append(box)
        self.text.configure(state="normal")
        self.text.window_create("end", window=box)
        self.text.configure(state="disabled")

class Example(object):
    def __init__(self):
        self.root = tk.Tk()
        self.dg = DynamicGrid(self.root, width=500, height=200)
        add_button  = tk.Button(self.root, text="Add", command=self.dg.add_box)

        add_button.pack()
        self.dg.pack(side="top", fill="both", expand=True)

        # add a few boxes to start
        for i in range(10):
            self.dg.add_box()

    def start(self):
        self.root.mainloop()
