python tkinter中的Frame控件用法详解

import tkinter as tk
win = tk.Tk()
for i in range(3):
    frm = tk.Frame(win)
    frm.pack(side=tk.LEFT, expand=tk.YES, fill=tk.Y)
    for j in range(3):
        btn = tk.Button(frm, text=f"{i,j}", width=10)
        btn.pack(side=tk.TOP,expand=tk.YES,fill=tk.X)
win.mainloop()

import tkinter as tk
def showFrames(frms):
    for i, frm in enumerate(frms):
        frm.pack(side=tk.LEFT, expand=tk.YES, fill=tk.Y)
        for j in range(3):
            btn = tk.Button(frm, text=f"{i,j}", width=10)
            btn.pack(side=tk.TOP,expand=tk.YES,fill=tk.X)
win = tk.Tk()
frms = [tk.Frame(win, bg='LightPink', bd=bd, takefocus=True,
    highlightbackground="gray", 
    highlightcolor="red",
    highlightthickness=bd,
    ) for bd in (2, 5, 10)]
showFrames(frms)
win.mainloop()

win = tk.Tk()
frms = [tk.LabelFrame(win, text=lc, labelanchor=lc, bd=5, 
    fg='green', takefocus=True, highlightbackground="gray", 
    highlightcolor="red") for lc in ("nw", "s", "ne")]
showFrames(frms)
win.mainloop()
