2 编写一个具有下拉菜单的导航栏

 1 from tkinter import *
 2 
 3 root = Tk()
 4 root.title("测试")
 5 root.geometry("400x400+400+200")
 6 # root.resizable(width = False, height = False)
 7 
 8 def hello() :
 9     l = Label(root, text = "hello boy")
10     l.pack()
11 
12 def save() :
13     l = Label(root, text = "保存文件成功")
14     l.pack()
15 
16 def cut() :
17     l = Label(root, text = "剪切成功")
18     l.pack()
19 
20 def copy() :
21     l = Label(root, text = "复制成功")
22     l.pack()
23 
24 def paste() :
25     l = Label(root, text = "粘贴成功")
26     l.pack()
27 
28 def about() :
29     l = Label(root, text = "我是开发者")
30     l.pack()
31 
32 menubar = Menu(root) # 创建菜单栏对象实例
33 
34 filemenu = Menu(menubar, tearoff = 0) # 创建下拉菜单栏对象实例
35 filemenu.add_command(label = "Open", command = hello)
36 filemenu.add_command(label = "Save", command = save)
37 filemenu.add_separator() # 添加分割线
38 filemenu.add_command(label = "Exit", command = root.quit)
39 
40 # 将下拉菜单添加到顶级菜单栏中
41 menubar.add_cascade(label = "File", menu = filemenu) 
42 
43 editmenu = Menu(menubar, tearoff = 0)
44 editmenu.add_command(label = "Cut", command = cut)
45 editmenu.add_command(label = "Copy", command = copy)
46 editmenu.add_separator()
47 editmenu.add_command(label = "Paste", command = paste)
48 menubar.add_cascade(label = "Edit", menu = editmenu)
49

51 helpmenu.add_command(label = "About", command = about)
52 menubar.add_cascade(label = "Help", menu = helpmenu)
