tkinter按键布局

在Tkinter中，可以使用grid()、pack()或place()等函数来布局按键。

使用grid()函数布局按键：

import tkinter as tk

root = tk.Tk()

btn1 = tk.Button(root, text="Button 1")
btn1.grid(row=0, column=0)

btn2 = tk.Button(root, text="Button 2")
btn2.grid(row=0, column=1)

btn3 = tk.Button(root, text="Button 3")
btn3.grid(row=1, column=0)

btn4 = tk.Button(root, text="Button 4")
btn4.grid(row=1, column=1)

root.mainloop()

使用pack()函数布局按键：

import tkinter as tk

root = tk.Tk()

btn1 = tk.Button(root, text="Button 1")
btn1.pack(side="left")

btn2 = tk.Button(root, text="Button 2")
btn2.pack(side="left")

btn3 = tk.Button(root, text="Button 3")
btn3.pack(side="right")

btn4 = tk.Button(root, text="Button 4")
btn4.pack(side="right")

root.mainloop()

使用place()函数布局按键：

import tkinter as tk

root = tk.Tk()

btn1 = tk.Button(root, text="Button 1")
btn1.place(x=20, y=20)

btn2 = tk.Button(root, text="Button 2")
btn2.place(x=80, y=20)

btn3 = tk.Button(root, text="Button 3")
btn3.place(x=20, y=60)

btn4 = tk.Button(root, text="Button 4")
btn4.place(x=80, y=60)

root.mainloop()
