我的代码：

import Tkinter as tk
from Tkinter import *
import datetime
class AddFrame(tk.Frame):
     def __init__(self, master=None, title = "default_title", width=400, height=400, bg='blue') :
         tk.Frame.__init__(self, master, width) 

         self.grid()
         self.master.title(title)

root = Tk()
root.title('Skeleton Test 1')
root.geometry('1920x1080')



ffcu0 = Frame(root, bg='blue', width=1080, height=700)
ffcu1 = Frame(root, bg='red', width=1080, height = 480)
ffcu2 = Frame(root, bg='green', width=270, height = 700)
ffcu3 = Frame(root, bg='blue', width=270, height = 480)
titleres='research'
app = AddFrame(master=root, title=titleres, width=400)


ffcu0.grid(row=0, column=0)
ffcu1.grid(row=2, column=0)
ffcu2.grid(row=0, column=1)
ffcu3.grid(row=2, column=1)

app.mainloop()

Answer 1

width是仅限关键字的参数。您必须以width=width的形式提供它。

class AddFrame(tk.Frame):
     def __init__(self, master=None, title = "default_title", width=400, height=400, bg='blue') :
         tk.Frame.__init__(self, master, width=width)

tkinter小部件的所有初始化参数都只是关键字，self和master除外。

AttributeError背后的原因是什么：＆＃39; int＆＃39;对象没有属性＆＃39; items＆＃39;？
