Tkinter 我想添加背景图像并希望在其上显示小部件，但小部件隐藏在图像后面

Question

the arc is hiding behind the image and i want to display it above the image and how to add more images which overlay on he background image

from itertools import cycle
from random import randrange
from tkinter import Tk , Canvas , messagebox , font
from tkinter import *
from tkinter.ttk import *

canvasw = 1200
canvash = 800

win = Tk()

c = Canvas(win, bg="blue", height=canvash, width=canvasw)
backg = PhotoImage(file = "back.png")
background_label = Label(win, image=backg)
background_label.place(x=0, y=0, relwidth=1, relheight=1)

eg = PhotoImage(file = "eg.png")
ep = PhotoImage(file = "ep.png")
er = PhotoImage(file = "er.png")
ey = PhotoImage(file = "ey.png")


ew = 45
eh = 55
es = 10

ev = 500
ei = 4000
dfcl = 0.95
catchcol = 'black'
catw = 100
cath = 100
catsx1 = canvasw / 2 - catw /2
catsy1 = canvash - cath -20
catsx2 = catsx1 + catw 
catsy2 = catsy1 + cath
cat = c.create_arc(catsx1,catsy1,catsx2,catsy2, start= 200 ,extent = 140, style='arc', outline=catchcol, width=3) 

c.pack()
win.mainloop()

the arc is hiding behind the image and i want to display it above the image

Answer 1

relwidth=1, relheight=1 is causing the the arc not be shown

so do

background_label.place(x=0, y=0)

relwidth=1, relheight=1 sets the label to be as big as the window, so the label will cover everything.

Answer 2

You should use create_image() to put the background image into canvas instead of using label:

c.create_image(0, 0, image=backg, anchor='nw')

Note that you should avoid importing modules as below:

from tkinter import Tk , Canvas , messagebox , font
from tkinter import *
from tkinter.ttk import *

The first import is override by the second import, so the first import is not necessary. Also some of the widgets in tkinter will be override by the third import, ie widgets from ttk .

You should import the modules as below:

import tkinter as tk
from tkinter import ttk
