Class For Picture View That Change Pic On Mouse Click

I want to make a class that has a picture and it is changed to the next one by mouse click.I'm new to oop, my idea here was to make class similar to real life where there is new cl

Solution 1:

Below example produces a simple image viewer tested with path of C:\Users\Public\Pictures\Sample Pictures, let me know if anything's unclear:

import tkinter as tk
from PIL import Image, ImageTk
#required for getting files in a path
import os

class ImageViewer(tk.Label):
    def __init__(self, master, path):
        super().__init__(master)

        self.path = path
        self.image_index = 0

        self.list_image_files()
        self.show_image()

        self.bind('<Button-1>', self.show_next_image)

    def list_files(self):
        (_, _, filenames) = next(os.walk(self.path))
        return filenames

    def list_image_files(self):
        self.image_files = list()
        for a_file in self.list_files():
            if a_file.lower().endswith(('.jpg', '.png', '.jpeg')):
                self.image_files.append(a_file)

    def show_image(self):
        img = Image.open(self.path + "\\" + self.image_files[self.image_index])
        self.img = ImageTk.PhotoImage(img)
        self['image'] = self.img

    def show_next_image(self, *args):
        self.image_index = (self.image_index + 1) % len(self.image_files)
        self.show_image()

root = tk.Tk()

mypath = r"C:\Users\Public\Pictures\Sample Pictures"
a = ImageViewer(root, mypath)
a.pack()

root.mainloop()
