python tkiner实现 一个小小的图片翻页功能的示例代码

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
