1、canvas

import tkinter as tk
    window = tk.Tk()
    window.title("The window")
    window.geometry("400x300")
    
    canvas = tk.Canvas(window, bg='blue', height=100, width=200)
    #添加图片
    #image_file = tk.PhotoImage(file='ins.gif')
    #image = canvas.create_image(10,10,anchor='nw',image=image_file)
    #创建直线
    x0,y0,x1,y1 = 50,50,80,80
    line = canvas.create_line(x0,y0,x1,y1)
    #创建一个圆
    oval = canvas.create_oval(x0,y0,x1,y1,fill='red')
    #创建一个扇形
    arc = canvas.create_arc(x0+30,y0+30,x1+30,y1+30,start=0,extent=180,fill='yellow')
    #创建一个长方形
    rect = canvas.create_rectangle(100,30,100+20,30+20)
    canvas.pack()
    
    def moveit():
        canvas.move(rect,0,8)
    
    b = tk.Button(window,text='move',command=moveit)
    b.pack()
    window.mainloop()

注：tkinter 只能打开\*.gif 图片。如要打开其他图片，则添加其它库 如pillow 或 pil

2、菜单栏   Menu

import tkinter as tk
    window = tk.Tk()
    window.title("The window")
    window.geometry("400x300")
    
    l = tk.Label(window,text='',bg='red')
    l.pack()
    
    counter = 0
    def do_job():
        global counter
        l.config(text='do ' + str(counter))
        counter += 1
    
    #创建一个菜单栏
    menubar = tk.Menu(window)
    
    #在menubar中创建filemenu菜单单元
    filemenu = tk.Menu(menubar,tearoff=0)
    #将上面定义的空菜单命名为file，放在菜单栏中
    menubar.add_cascade(label='File',menu=filemenu)
    
    filemenu.add_command(label='New',command=do_job)
    filemenu.add_command(label='Open',command=do_job)
    filemenu.add_command(label='Save',command=do_job)
    filemenu.add_separator()
    filemenu.add_command(label='Exit',command=window.quit)
    window.config(menu=menubar)
    
    editmenu = tk.Menu(menubar,tearoff=0)
    menubar.add_cascade(label='Edit',menu=editmenu)
    editmenu.add_command(label='Cut',command=do_job)
    editmenu.add_command(label='Copy',command=do_job)
    editmenu.add_command(label='Paste',command=do_job)
    
    #和上面定义菜单一样，不过此处在file上创建一个空菜单
    submenu = tk.Menu(filemenu)
    filemenu.add_cascade(label='Import',menu=submenu,underline=0)
    submenu.add_command(label='Submenu1',command=do_job)
