How do I center a frame within a frame in Tkinter?

问题

I have a frame that I fixed the size of using the grid_propagate() method. I'd like to center a frame within this frame. How do I go about this?

回答1:

pack it to fill in all directions. Add padding as needed.

Or, use place which lets you use relative or absolute positioning. You can use a relative x/y of .5/.5 and an anchor of "c" (center).

import Tkinter as tk

root=tk.Tk()
f1 = tk.Frame(width=200, height=200, background="red")
f2 = tk.Frame(width=100, height=100, background="blue")

f1.pack(fill="both", expand=True, padx=20, pady=20)
f2.place(in_=f1, anchor="c", relx=.5, rely=.5)

root.mainloop()
