想创造一个简单的滚动条，大神求解

胖大昕

1. sb = Scrollbar(window_sign_up)
   
2. sb.pack(side=RIGHT, fill=Y)
   
3. lb = Listbox(window_sign_up, yscrollcommand=sb.set)
   
4. for i in range(1000):
   
5.     lb.insert(END, str(i))
   
6. lb.pack(side=LEFT, fill=BOTH)
   
7. sb.config(command=lb.yview)

本人小白，就想创造一个简单的滚动条，结果把小甲鱼的程序搬过来发现我自己原来的内容还没有滚动，而且左侧又多了很多东西

1. from tkinter import *
   
2. import tkinter as tk
   
3. 
   
4. 
   
5. 
   
6. def add_2():
   
7.     calc = []
   
8.     exp1 = nunmber101.get()
   
9.     exp2 = nunmber102.get()
   
10.     calc.append(float(exp1))
    
11.     calc.append(float(exp2))
    
12.     calc.append(calc[0]+calc[1])
    
13.     v.set(round(calc[2],3))
    
14.    
    
15. 
    
16. ii=200
    
17. window_sign_up =tk.Tk()
    
18. window_sign_up.geometry('500x500')
    
19. window_sign_up.title('10以内加法')
    
20.    
    
21. 
    
22. 
    
23. nunmber101 = tk.StringVar()#给第一个框输入数字，默认为2
    
24. nunmber101.set('2')
    
25. tk.Label(window_sign_up, text='请输入你的第一个数：').place(x=10, y= ii)

27. entry_nunmber101.place(x=150, y=ii)
    
28. 
    
29. nunmber102 = tk.StringVar()#给第二个框输入数字，默认为3
    
30. nunmber102.set('3')
    
31. tk.Label(window_sign_up, text='请输入你的第二个数：').place(x=10, y= ii+150)
    
32. entry_nunmber102 = tk.Entry(window_sign_up, textvariable=nunmber102)

35. #设置按钮，点击计算
    
36. btn_2=tk.Button(window_sign_up,text='加计算',command=add_2,font=('Arial',30))
    
37. btn_2.place(x=150,y=ii+200)
    
38.

42. e1 = tk.Entry(window_sign_up,textvariable = v,width = 20)

您好，我就想做一个窗口的滚动，不想带有数字，您看您能帮我看看该怎么写吗？

阴阳神万物主

你可以把除了滚动条的所有窗口组件都放在一个 Canvas 组件里面，然后让滚动条和那个 Canvas 组件联动比如：

1. import tkinter as tk
   
2. root = tk.Tk()
   
3. 
   
4. ca = tk.Canvas(root,bg='#FFFFFF',height=50,width=100,scrollregion=(-100,-200,100,200))
   
5. sc = tk.Scrollbar(root,command=ca.yview)
   
6. sc.pack(side=tk.RIGHT,fill=tk.Y)
   
7. ca.pack(side=tk.LEFT,expand=True,fill=tk.BOTH)
   
8. ca.config(yscrollcommand=sc.set)
   
9. fr = tk.Frame(ca)
   
10. l1 = tk.Label(fr,text='我在上边,\n其实\n我就是\n想让\n标签长高',bg='#FF0000',fg='#00FFFF')
    
11. l2 = tk.Label(fr,text='我在中间,\n其实\n我就是\n想让\n标签长高',bg='#00FF00',fg='#FF00FF')
    
12. l3 = tk.Label(fr,text='我在下边,\n其实\n我就是\n想让\n标签长高',bg='#0000FF',fg='#FFFF00')
    
13. l1.pack()
    
14. l2.pack()
    
15. l3.pack()
    
16. ca.create_window((50,25),window=fr)
    
17. tk.mainloop()
