如何使用下面指定格式的Tkinter制作GUI？

Question

在下面給出的代碼中，我想以如下方式創建GUI：1）在第一幀：第一行：“ x”（檢查按鈕），“ x”（檢查按鈕）的右側必須為“選擇xFile”（按鈕）和“選擇xFile”（按鈕）的權利必須為“清除”（按鈕），並且同樣在第二行中：“ y”。 僅當選中“ x”復選框時，才應啟用“選擇xFile”按鈕。 當單擊“選擇xFile”時，它必須打開文件對話框。 並且選擇的文件內容應使用中間框（帶有水平和垂直滾動條）的“輸入數據”（標簽）下方的“描述框”顯示。 而且，當單擊“清除”按鈕時，僅必須清除“描述框”中選定的文件內容（選擇的x或y文件），並且必須啟用“選擇xFile”（按鈕）或“選擇yFile”（按鈕）再次執行任務（即打開文件對話框）。 在“說明框”下面必須包含“重置”按鈕，在“重置”按鈕的右側必須是中間框架中間部分的“提交”按鈕。 單擊“重置”按鈕時，必須清除“描述框”中顯示的所有內容，並且必須取消選中所有復選框，以便用戶可以再次執行選擇過程。 在底部框架的“模型輸出”（標簽）下，必須有一個“描述框”以及“水平”和“垂直”滾動條。 在“說明框”的下方，必須包含“退出”按鈕，該按鈕位於“底部框架”的中間。

from tkinter import *

def forButton1():
    filename1 = askopenfilename()

    with open(filename1) as f:
        for i in f:
            myList.insert(END, i)

    print(filename1)

def forButton2():
    filename1 = askopenfilename()

    with open(filename1) as f:
        for i in f:
            myList.insert(END, i)

    print(filename1)

def forButton7():
    root.destroy()

root = Tk()
root.title("Spatialization of DSSAT")

topFrame = LabelFrame(root, text = "Select input file")

MyVar1 = IntVar()
MyVar2 = IntVar()

MyCheckbutton1 = Checkbutton(topFrame, text="x", variable=MyVar1)
#MyCheckbutton1.grid(row=0, column=0)
MyCheckbutton1.pack()

MyCheckbutton2 = Checkbutton(topFrame, text="y", variable=MyVar2)
#MyCheckbutton2.grid(row=1, column=0)
MyCheckbutton2.pack()

Button1 = Button(topFrame, text = "Choose xFile", command = forButton1)
#button1.grid(row=0, column=1)
Button1.pack()
Button2 = Button(topFrame, text = "Choose yFile", command = forButton2)
#button2.grid(row=0, column=1)
Button2.pack()
Button3 = Button(topFrame, text = "Clear")
Button3.pack()
Button4 = Button(topFrame, text = "Clear")
Button4.pack()
topFrame.pack(side=TOP)

middleFrame = Frame(root)
label1 = Label(middleFrame, text = "Input data:")
label1.grid(row = 4)


scrollbar = Scrollbar(middleFrame)


myList = Listbox(middleFrame, yscrollcommand = scrollbar.set)
myList.pack()
scrollbar.config( command = myList.yview )
scrollbar.pack()

Button5 = Button(middleFrame, text = "Reset")
#button1.grid(row=0, column=1)
Button5.pack()

Button6 = Button(middleFrame, text = "Submit")
#button1.grid(row=0, column=1)
Button6.pack()

middleFrame.pack()

bottomFrame = Frame(root)

label2 = Label(bottomFrame, text = "Model Output:")
label2.grid(row = 10)

Button7 = Button(bottomFrame, text = "Exit", command = forButton7)
#button1.grid(row=0, column=1)
Button7.pack()

bottomFrame.pack()

root.geometry("500x500")
root.mainloop()

在這里，我已經修復了問題中給定小部件（而不是其功能）的放置。 您可以按照以下方式獲取所需的格式：

from tkinter import *
from tkinter import filedialog

def forButton1():
    filename1 = filedialog.askopenfilename()

    with open(filename1) as f:
        for i in f:
            myList.insert(END, i)

    print(filename1)

def forButton2():
    filename1 = filedialog.askopenfilename()

    with open(filename1) as f:
        for i in f:
            myList.insert(END, i)

    print(filename1)

def forButton7():
    root.destroy()

root = Tk()
root.title("Spatialization of DSSAT")

root.grid_columnconfigure(0, weight=1)

topFrame = LabelFrame(root, text="Select input file")
topFrame.grid(row=0, column=0, padx=8, pady=8, sticky=N+E+S+W)
topFrame.grid_rowconfigure(0, weight=1)
topFrame.grid_rowconfigure(1, weight=1)
topFrame.grid_columnconfigure(0, weight=1)
topFrame.grid_columnconfigure(1, weight=1)
topFrame.grid_columnconfigure(2, weight=1)

middleFrame = LabelFrame(root, text="Input data")
middleFrame.grid(row=1, column=0, padx=8, pady=8, sticky=N+E+S+W)
middleFrame.grid_rowconfigure(0, weight=1)
middleFrame.grid_rowconfigure(1, weight=0)
middleFrame.grid_columnconfigure(0, weight=1)
middleFrame.grid_columnconfigure(1, weight=1)

bottomFrame = LabelFrame(root, text="Model Output")
bottomFrame.grid(row=2, column=0, padx=8, pady=8, sticky=N+E+S+W)
bottomFrame.grid_rowconfigure(0, weight=1)
bottomFrame.grid_columnconfigure(0, weight=1)

MyVar1 = IntVar()
MyVar2 = IntVar()

MyCheckbutton1 = Checkbutton(topFrame, text="x", variable=MyVar1)
MyCheckbutton1.grid(row=0, column=0, padx=4, pady=4)
Button1 = Button(topFrame, text="Choose xFile", command=forButton1)
Button1.grid(row=0, column=1, padx=4, pady=4)
Button3 = Button(topFrame, text="Clear")
Button3.grid(row=0, column=2, padx=4, pady=4)

MyCheckbutton2 = Checkbutton(topFrame, text="y", variable=MyVar2)
MyCheckbutton2.grid(row=1, column=0, padx=4, pady=4)
Button2 = Button(topFrame, text="Choose yFile", command=forButton2)
Button2.grid(row=1, column=1, padx=4, pady=4)
Button4 = Button(topFrame, text="Clear")
Button4.grid(row=1, column=2, padx=4, pady=4)

innerMiddleFrame = Frame(middleFrame)
innerMiddleFrame.grid(row=0, column=0, columnspan=2, padx=4, pady=4)
innerMiddleFrame.grid_columnconfigure(0, weight=1)
innerMiddleFrame.grid_columnconfigure(1, weight=0)

scrollbar = Scrollbar(innerMiddleFrame)
myList = Listbox(innerMiddleFrame, yscrollcommand=scrollbar.set)
myList.grid(row=0, column=0, sticky=N+E+S+W)
scrollbar.config(command=myList.yview)
scrollbar.grid(row=0, column=1, sticky=N+E+S+W)

Button5 = Button(middleFrame, text="Reset")
Button5.grid(row=1, column=0, padx=4, pady=4)

Button6 = Button(middleFrame, text="Submit")
Button6.grid(row=1, column=1, padx=4, pady=4)

Button7 = Button(bottomFrame, text="Exit", command=forButton7)
Button7.grid(row=0, column=0, padx=4, pady=4)
