【莫烦Python】 Tkinter学习笔记 8.Canvas

直接划重点！

canvas.create_image中的anchor参数表示以被插入的图片哪个点为参照，可选nw，n，w，ne, e, se, s, sw, center
canvas.create_arc作出一个扇形， start和extent分别表示起始和终止角

import tkinter as tk

window = tk.Tk()    #create window object
window.title('my window')
window.geometry('200x200')  #ATTENTION!!! use x instead of * here

canvas = tk.Canvas(window, bg='blue',
                   height=100, width=200)
image_file = tk.PhotoImage(file='1.png')
image = canvas.create_image(0,0, anchor='nw',
                            image=image_file)
x0, y0, x1, y1 = 50, 50, 80, 80
line = canvas.create_line(x0, y0, x1, y1)
oval = canvas.create_oval(x0, y0, x1, y1, fill='red')
arc = canvas.create_arc(x0+30, y0+30, x1+30, y1+30, start=0, extent=180)
rect = canvas.create_rectangle(100, 30, 100+20, 30+20)
canvas.pack()
def moveit():
    canvas.move(rect, 0, 2)

b = tk.Button(window,
              text='move',
              command=moveit).pack()
window.mainloop()   #refresh
