如果单击了按钮，如何跟踪

Question

我正在制作一个记忆游戏，但我不知道如何跟踪按钮是否被点击。如果单击时两个图像不匹配，我希望图块更改回默认图像，但如果它们匹配则保留为新图像。

    def __init__(self, master):     
        frame=Frame(master)
        frame.grid() 
        master.title("Let's play Kitten Memory!")
        master.iconbitmap(r"default.ico")


        self.button1=ttk.Button(root)
        self.button1.grid(row = 0, column = 0)
        self.photo1 = tk.PhotoImage(file="defaultPic.png")
        self.button1.config(image=self.photo1, command=lambda: showImage(1))

        self.button2=ttk.Button(root)
        self.button2.grid(row=0, column=1)
        self.photo2 = tk.PhotoImage(file="defaultPic.png")
        self.button2.config(image=self.photo2, command=lambda: showImage(2))

        self.button3=ttk.Button(root)
        self.button3.grid(row=0, column=2)
        self.photo3 = tk.PhotoImage(file="defaultPic.png")

        class showImage(MemoryBricks):
            def __init__(self, master):

                if master == 1:

                    load1Size = load1.resize((145,145))
                    render1 = ImageTk.PhotoImage (load1Size)           
                    img1 = Label(image=render1)
                    img1.image = render1 
                    img1.grid(row = 0, column = 0)



                if master == 2:
                    load1 = Image.open('Kittens2.GIF')
                    load1Size = load1.resize((145,145))
                    render1 = ImageTk.PhotoImage (load1Size)           
                    img1 = Label(image=render1)
                    img1.image = render1                
                    img1.grid(row=0, column=1)   



                if master == 3:
                    load1 = Image.open('Kittens3.GIF')
                    load1Size = load1.resize((145,145))
                    render1 = ImageTk.PhotoImage (load1Size)           
                    img1 = Label(image=render1)
                    img1.image = render1                 
                    img1.grid(row=0, column=2)  



                if master == 4:
                    load1 = Image.open('Kittens1.GIF')
                    load1Size = load1.resize((145,145))
                    render1 = ImageTk.PhotoImage (load1Size)           
                    img1 = Label(image=render1)
                    img1.image = render1                 
                    img1.grid(row=1, column=0)  



                if master == 5:
                    load1 = Image.open('Kittens2.GIF')
                    load1Size = load1.resize((145,145))
                    render1 = ImageTk.PhotoImage (load1Size)           
                    img1 = Label(image=render1)
                    img1.image = render1                 
                    img1.grid(row=1, column=1)  


                if master == 6:
                    load1 = Image.open('Kittens3.GIF')
                    load1Size = load1.resize((145,145))
                    render1 = ImageTk.PhotoImage (load1Size)           
                    img1 = Label(image=render1)
                    img1.image = render1                 
                    img1.grid(row=1, column=2)

#skapar fönstret
root=Tk()  
start_time = time.time()

#root blir master 
mem=MemoryBricks(root)

root.mainloop()


elapsed_time = time.time() - start_time

print("Your time is", elapsed_time)

我相信我可能必须创建一个新类或一个函数。或者有人对如何轻松做到这一点有任何建议吗？

Answer 1

你可以有一个辅助变量作为一个标志。

例如将其定义为self.flag = False。单击按钮时，将变量的值更改为 True (self.flag = True)，这是您可以跟踪按钮是否被按下的方式

例如，您想跟踪 button1 是否被点击：

 class MemoryBricks:
      def __init__(self, master):
           # Define "flag variable" for button1
           self.flag_btn1 = False

在单击按钮1时将执行的函数（或部分代码）中更改标志的状态：

 class showImage(MemoryBricks):
      def __init__(self, master):
           if master == 1:
                # Change state of the flag
                self.flag_btn1 = True
                load1 = Image.open('Kittens1.GIF')
                load1Size = load1.resize((145, 145))
                render1 = ImageTk.PhotoImage(load1Size)
                img1 = Label(image=render1)
                img1.image = render1
                img1.grid(row=0, column=0)

现在您可以检查是否单击了 button1：

例如，在某些信号/动作上：

 if self.flag_btn1: # True
      print("button1 was clicked")
 else: # False
      print("button1 wasn't clicked")
