python - Tkinter:在网格布局中获取按钮上方的图像

Question

我是 tkinter 的新手，我试图制作一个 GUI，顶部有一个图像，该图像下方有 4 个按钮区域，这是选择答案的方法。但是，到目前为止，通过代码，我创建的按钮似乎停留在左上角，根本不会在图像下方移动，有人知道这个问题的解决方案吗？

import Tkinter as tk
from Tkinter import *
from Tkinter import PhotoImage

root = Tk()

class Class1(Frame):

    def __init__(self, master):
        Frame.__init__(self, master)
        self.grid()

        self.master = master        
        self.question1_UI()

    def question1_UI(self):

        self.master.title("GUI")        

        gif1 = PhotoImage(file = 'Image.gif')

        label1 = Label(image=gif1)
        label1.image = gif1 
        label1.grid(row=1, column = 0, columnspan = 2, sticky=NW)

        questionAButton = Button(self, text='Submit',font=('MS', 8,'bold'))
        questionAButton.grid(row = 2, column = 1, sticky = S)
        questionBButton = Button(self, text='Submit',font=('MS', 8,'bold'))
        questionBButton.grid(row = 2, column = 2, sticky = S)
        questionCButton = Button(self, text='Submit',font=('MS', 8,'bold'))
        questionCButton.grid(row = 3, column = 3, sticky = S)
        questionDButton = Button(self, text='Submit',font=('MS', 8,'bold'))
        questionDButton.grid(row = 3, column = 4, sticky = S)



def main():


    ex = Class1(root)
    root.geometry("{0}x{1}+0+0".format(root.winfo_screenwidth(),
    root.winfo_screenheight()))         
    root.mainloop()  


if __name__ == '__main__':
    main()

您没有使用 self 作为 label1 的父级。此外，网格管理器从第 0 行开始:

def question1_UI(self):
    # ...
    label1 = Label(self, image=gif1)
    label1.image = gif1 
    label1.grid(row = 0, column = 0, columnspan = 2, sticky=NW)

    questionAButton = Button(self, text='Submit',font=('MS', 8,'bold'))
    questionAButton.grid(row = 1, column = 0, sticky = S)
    questionBButton = Button(self, text='Submit',font=('MS', 8,'bold'))
    questionBButton.grid(row = 1, column = 1, sticky = S)
    questionCButton = Button(self, text='Submit',font=('MS', 8,'bold'))
    questionCButton.grid(row = 2, column = 0, sticky = S)
    questionDButton = Button(self, text='Submit',font=('MS', 8,'bold'))
    questionDButton.grid(row = 2, column = 1, sticky = S)
