编写一个python代码,利用Gui的 tkinter库设计一个4*4的华容道游戏。 将一张图分为十六小块，每个方块上显示1小块图片,共15个方块上有图片，通过数字华容道的规则，顺序无误后拼成完整图片，图片存储在桌面。

好的，我可以为您提供代码实现。 请注意，由于我是一个AI语言模型，无法在本地访问您的桌面，因此在此代码中，我将使用一张名为 "hua.jpg" 的示例图像。

import tkinter as tk
from tkinter import messagebox
from PIL import Image, ImageTk
import random

class HuaRongDao:
    def __init__(self, master):
        self.master = master
        self.master.title("华容道")
        self.master.resizable(False, False)
        self.master.geometry("400x400")

        self.image = Image.open("hua.jpg")
        self.pieces = []
        self.empty_piece = None
        self.piece_size = (self.image.width // 4, self.image.height // 4)
        
        self.create_widgets()
        self.cut_image()
        self.shuffle()
    
    def create_widgets(self):
        self.canvas = tk.Canvas(self.master, width=self.image.width, height=self.image.height)
        self.canvas.pack()

        self.button_shuffle = tk.Button(self.master, text="重新开始", command=self.shuffle)
        self.button_shuffle.pack()

    def cut_image(self):
        for i in range(4):
            for j in range(4):
                x = j * self.piece_size[0]
                y = i * self.piece_size[1]
                piece = self.image.crop((x, y, x+self.piece_size[0], y+self.piece_size[1]))
                if i == 3 and j == 3:
                    self.empty_piece = {"piece": None, "position": (i, j)}
                else:
                    self.pieces.append({"piece": piece, "position": (i, j)})
    
    def shuffle(self):
        random.shuffle(self.pieces)
        for i, piece in enumerate(self.pieces):
            position = (i // 4, i % 4)
            piece["position"] = position
            self.draw_piece(piece, position)
        
        self.empty_piece["position"] = (3, 3)
        self.canvas.delete("empty")
        self.canvas.create_rectangle(3 * self.piece_size[0], 3 * self.piece_size[1], 4 * self.piece_size[0], 4 * self.piece_size[1], fill="white", tags="empty")
    
    def draw_piece(self, piece, position):
        x0 = position[1] * self.piece_size[0]
        y0 = position[0] * self.piece_size[1]
        x1 = x0 + self.piece_size[0]
        y1 = y0 + self.piece_size[1]
        image = ImageTk.PhotoImage(piece["piece"])
        self.canvas.create_image(x0, y0, image=image, anchor="nw", tags="piece")
        self.canvas.itemconfig("piece", image=image)
        self.canvas.coords("piece", x0, y0)
        self.canvas.tag_bind("piece", "<Button-1>", lambda event, arg=piece: self.move_piece(arg))
    
    def move_piece(self, piece):
        position = piece["position"]
        empty_position = self.empty_piece["position"]
        if position[0] == empty_position[0] and abs(position[1] - empty_position[1]) == 1:
            self.swap_pieces(piece, self.empty_piece)
        elif position[1] == empty_position[1] and abs(position[0] - empty_position[0]) == 1:
            self.swap_pieces(piece, self.empty_piece)
        
        if all([piece["position"] == (i // 4, i % 4) for i, piece in enumerate(self.pieces)]):
            messagebox.showinfo("完成！", "你完成了一张华容道拼图！")
    
    def swap_pieces(self, piece1, piece2):
        piece1_position = piece1["position"]
        piece2_position = piece2["position"]
        piece1["position"] = piece2_position
        piece2["position"] = piece1_position
        x0 = piece1_position[1] * self.piece_size[0]
        y0 = piece1_position[0] * self.piece_size[1]
        self.canvas.coords("piece", x0, y0)
        self.empty_piece = piece1
    
root = tk.Tk()
app = HuaRongDao(root)
root.mainloop()

运行该程序后，您将看到一个4乘4的窗口，其中包含一个华容道拼图。 您可以单击任何一块拼图，将其移动到空白区域，以此来解决整个拼图。
