Question

我设计了一个简单的程序，该程序在顶部框架中显示图片，并通过底部框架中“注释”标签旁边的输入框进行文本输入。如果您按Enter键，则应转到另一张图片，依此类推。它可以在运行Windows 10的计算机上完美运行。但是，当我在朋友的Mac-book上打开它时，它仅显示图片，底部框架（文本标签和输入框）未显示。我尝试最大化窗口大小，以查看是否它是隐藏的，但它不存在。是否有理由在MacOS上表现不同？另外，如果您按Enter键，则可以毫无问题地转到下一张图像。

        self.max = 0
        for filename in os.listdir(self.directory):
            if(not filename[0] == '.'):

                self.pics[self.k] = filename
                self.k += 1
        self.max = self.k

        #Pack Everything
        self.panel.pack(side = 'top')

        openF = open(self.directory + '/My Comments.txt', 'a')
        #print('here')

        if comment == 'y':
            openF.write(self.pics[self.k] + '\t Good'  + '\n')

        elif comment == 'n':
            openF.write(self.pics[self.k] + '\t Bad' + '\n')


        elif comment == 'quit':
            self.k = self.max

        else:
            openF.write(self.pics[self.k] + '\t' + comment + '\n')

        openF.close()
        if(self.k + 1 < self.max):
            self.comment_entry.delete(0, 'end')
            self.k += 1
            self.img = ImageTk.PhotoImage(Image.open(self.directory + self.pics[self.k]))
            self.panel.configure(image = self.img)
            self.panel.update()
        else:
            messagebox.showinfo('Image Processor','There are no more pictures')
            self.window.destroy()

test = imageProcessor()

Tkinter未在MacOS上显示所有帧
