Question

在下面给出的代码中，我想以如下方式创建GUI：1）在顶部框架中：第一行：“ x”（检查按钮），“ x”（检查按钮）的右侧必须为“选择xFile” “（选择）xFile”（按钮）右侧的“（按钮）”必须为“清除”（按钮），并且同样在第二行中：“ y”。仅当选中“ x”复选框时，才应启用“选择xFile”按钮。当单击“选择xFile”时，它必须打开文件对话框。并且选择的文件内容应使用中间框（带有水平和垂直滚动条）的“输入数据”（标签）下方的“描述框”显示。而且，当单击“清除”按钮时，仅必须清除“描述框”中选定的文件内容（选择的x或y文件），并且必须启用“选择xFile”（按钮）或“选择yFile”（按钮）再次执行任务（即打开文件对话框）。在“说明框”下面必须包含“重置”按钮，在“重置”按钮的右侧必须是中间框架中间部分的“提交”按钮。单击“重置”按钮时，必须清除“描述框”中显示的所有内容，并且必须取消选中所有复选框，以便用户可以再次执行选择过程。在底部框架的“模型输出”（标签）下，必须有一个“描述框”以及“水平”和“垂直”滚动条。在“说明框”的下方，必须包含“退出”按钮，该按钮位于“底部框架”的中间。

    print(filename1)

    with open(filename1) as f:

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()

在这里，我已经修复了有问题的给定小部件（而不是其功能）的放置。您可以按照以下方式获取所需的格式：

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)

root.geometry("250x425")
root.mainloop()

如何使用下面指定格式的Tkinter制作GUI？
