python - 如何在 TK Inter 中使用图像和按钮？

Question

我是 Python 的新用户，我正在努力弄清楚如何在 TK Inter 中使用图像作为按钮。我目前正在为一个学校作业做一个小型项目，在那里我制作了一个小型音乐库，我希望它看起来不错。但是，由于缺少颜色，我的项目目前非常无聊。

如何从 youtube 合并此代码：

from tkinter import *

root = Tk()
root.title('hello')
root.geometry('400x400')

login_btn = PhotoImage(file='pc.png')

img_label = Label(image = login_btn)
img_label.pack(pady=20)

mainloop()

进入这个：

#     GUI     #
import tkinter as tk
from tkinter import *
from tkinter import filedialog


#     AUDIO   #
from pygame import mixer

#     DIRECTORY NAVIGATION   #
from os import walk

#     EXCEPTION HANDLER   #
import pygame

#     VOLUME CONTROL   #
from comtypes import CLSCTX_ALL
from pycaw.pycaw import AudioUtilities, IAudioEndpointVolume, ISimpleAudioVolume
from ctypes import cast, POINTER
# YOU MIGHT NEED TO PIP INSTALL THESE
# IF THOSE DONT WORK TRY
# py -m pip install [library]
# pip install pycaw
# pip install comtypes
# pip install psutil





class MP:
    
    def __init__(self, win):
        # Create Tkinter window
        win.geometry('600x300')
        win.title('Jared AIT Music Player')
        win.resizable(0, 0)
        win.iconbitmap('icon.ico')

        next_button.place(x=550,y=250, anchor='center')

        back_button = Button(win ,text = '<<',  width = 10, font = ('Arial', 10), command = self.back)
        back_button.place(x=450,y=250, anchor='center')

        #SLIDERS
        volume_slider = Scale(win, from_=100, to=0, orient=VERTICAL, command=self.volume, length=125)
        volume_slider.grid(row=0, column=1)

我正在寻找替换按钮：“加载”、“播放”、“暂停”、“停止”、“下一步”和“返回”。与图像。有人有想法吗？

下面是我最近实现可以作为图像加载的按钮的方式。有些功能与我的需求有关，因此您可能不需要全部。

# Method from my app class

def add_button(self, message, alias, x, y, function, args="", image_path="", subsample=0):
    if image_path != "":
        photo = PhotoImage(file = image_path)
        photo_image = photo.subsample(subsample, subsample)
        self.images[alias] = photo_image
        btn = Button(self.window, text=message, command=function, image=photo_image)
    else:
        btn = (Button(self.window, text=message, command=function)
        if args == "" else (Button(self.window, text=message, command=lambda:function(args))))
    btn.place(y=y, x=x)
    self.buttons[alias] = btn

#Add button to the app (I usually call in the init)
[...]
app.add_button(MY_MESSAGE, ALIAS_TO_STORE_THE_BUTTON, x, y, MYFUNCTION, "", "PATH_TO_IMAGE", 8)
