如何用python tkiner实现图片翻页功能？针对这个问题，这篇文章详细介绍了相对应的分析和解答，希望可以帮助更多想解决这个问题的小伙伴找到更简单易行的方法。

具体代码如下所示：

import tkinter as tk

import tkinter.messagebox

import copy

import os,sys

def get_picture(dirs):

'''获得所有图片'''

picture_list = []

for dir,dir_abs,files in os.walk(dirs):

for file in files:

if file.endswith('.gif'):

picture_list.append(os.path.join(dir,file))

return picture_list

class Window:

button_list = []

object_list = []

pictures = get_picture(picture_path)

file = pictures[0]

is_show = True

index = 0

image_file = ''

def __init__(self):

'''创建窗口和frame'''

self.window = tk.Tk()

self.window.title('my window')

self.window.geometry('600x600')

self.frame = tk.Frame(self.window)

self.frame.pack()

self.frame_l = tk.Frame(self.frame)

self.frame_r = tk.Frame(self.frame)

self.frame_l.pack(side='left')

self.frame_r.pack(side='right')

self.frame_ll = tk.Frame(self.frame_r)

self.frame_rr = tk.Frame(self.frame_r)

self.frame_ll.pack(side='left')

self.frame_rr.pack(side='right')

def next_picture(self):

'''下一张图片'''

self.index = self.pictures.index(self.file)

self.index += 1

if self.index < len(self.pictures):

self.checkout_button()

self.file = self.pictures[self.index]

self.create_canvas(self.file)

else:

self.index = len(self.pictures) - 1

tkinter.messagebox.showinfo('提示', '已近是最后一张了')

def checkout_button(self):

'''判断列表中是否只有button对象'''

object_list_copy = copy.copy(self.object_list)

for ob in self.object_list:

if ob in self.button_list:

pass

else:

b = object_list_copy.pop(self.object_list.index(ob))

b.destroy()

self.object_list = object_list_copy

def pre_picture(self):

'''上一页'''

self.index = self.pictures.index(self.file)

self.index -= 1

if self.index >= 0:

self.checkout_button()

self.file = self.pictures[self.index]

self.create_canvas(self.file)

else:

self.index = 0

tkinter.messagebox.showinfo('提示', '已经是第一张了')

def show_picture(self):

'''展示图片和翻页按钮'''

self.file = self.pictures[0]

if self.is_show:

self.is_show = False

self.create_canvas(self.file)

button1 = tk.Button(self.frame_ll, text='上一张', width=10, height=1, command=self.pre_picture)

button1.pack()

button2 = tk.Button(self.frame_rr, text='下一张', width=10, height=1, command=self.next_picture)

button2.pack()

self.button_list.append(button1)

self.button_list.append(button2)

self.object_list.extend(self.button_list)

else:

self.is_show = True

while self.object_list:

o = self.object_list.pop()

o.destroy()

def new_button(self):

'''创建展示按钮'''

tk.Button(self.frame_l, text='图片展示', width=10, height=1, command=self.show_picture).pack()

def create_canvas(self,file):

'''用画布展示图片'''

self.image_file = tk.PhotoImage(file=file)

canvas = tk.Canvas(self.frame_r, height=500, width=600)

canvas.create_image(1, 1, anchor='nw', image=self.image_file)

canvas.pack()

self.object_list.append(canvas)

def run(self):

'''主程序调用'''

self.window.mainloop()

if __name__ == '__main__':

w = Window()

w.new_button()

w.run()

样式如下：有点丑，不过功能没毛病，就先这么着吧~~~

点击图片展示之后

上一页下一页可以用，再次点击图片展示
