如何在Python Tkinter中添加框架？

Question

在下面给出的代码中，我只想在选中“土壤”复选框时打开文件打开对话框，然后对“天气”复选框重复相同的操作。

需要将“土壤”检查按钮，“天气”检查按钮和“提交”按钮放置在GUI框架的左侧，并且滚动条应包含2个打开文件的详细信息（从“文件打开”对话框中选择的文件框”（以“文本”格式），将其放置在GUI框架的右侧

from tkinter import *
from tkinter import Tk
from tkinter.filedialog import askopenfilename

win = Tk()

frame = Frame(win)
frame.pack()

rightframe = Frame(win)
rightframe.pack( side = RIGHT )

#frame_name = Frame(win)
#frame_address = Frame(win)

win.title("Spatialization of DSSAT model")

w = 800
h = 400

ws = win.winfo_screenwidth()
hs = win.winfo_screenheight()

x = (ws/2) - (w/2)
y = (hs/2) - (h/2)

win.geometry('%dx%d+%d+%d' % (w, h, x, y))

def forCheckbutton1():
    filename1 = askopenfilename()
    print(filename1)

def forCheckbutton2():
    filename2 = askopenfilename()
    print(filename2)

def forMuButton1():
    win.destroy()

def var_states():
    print("soil: %d, \nweather:%d" % (MyVar1.get(), MyVar2.get()))

MyLabel1 = Label(frame, text="Select:")
MyLabel1.grid(row=0, column=0, sticky=W)


MyVar1 = IntVar()
MyVar2 = IntVar()

MyCheckbutton1 = Checkbutton(frame, text="soil", variable=MyVar1, command=forCheckbutton1)
MyCheckbutton1.grid(row=1, column=0, sticky=W)

MyCheckbutton2 = Checkbutton(frame, text="weather", variable=MyVar2, command=forCheckbutton2)
MyCheckbutton2.grid(row=2, column=0, sticky=W)


MyButton1 = Button(frame, text="Submit", width=10, command=forMuButton1)
MyButton1.grid(row=5, columnspan=3)

scrollbar = Scrollbar(rightframe)
scrollbar.pack( side = RIGHT, fill = Y )

myList = Listbox(rightframe, yscrollcommand = scrollbar.set )
forCheckbutton1()
forCheckbutton2()

myList.pack( side = LEFT, fill = BOTH )
scrollbar.config( command = myList.yview )

win.mainloop()

Answer 1

仅在选中按钮时才从主forCheckbutton2()删除forCheckbutton1()和forCheckbutton2()以打开对话框。 要将框放置在左侧，请将side设置为LEFT 。 为了使滚动条中的文件内容完整，请在功能中打开文件。 尝试这个：

from tkinter import *
from tkinter import Tk
from tkinter.filedialog import askopenfilename

win = Tk()

frame = Frame(win)
frame.pack(side=LEFT)

rightframe = Frame(win)
rightframe.pack( side = RIGHT )

win.title("Spatialization of DSSAT model")

w = 800
h = 400

ws = win.winfo_screenwidth()
hs = win.winfo_screenheight()

x = (ws/2) - (w/2)
y = (hs/2) - (h/2)

win.geometry('%dx%d+%d+%d' % (w, h, x, y))

def forCheckbutton1():
    filename1 = askopenfilename()

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

    print(filename1)

def forCheckbutton2():
    filename2 = askopenfilename()

    with open(filename2) as f:
        for i in f:
            myList.insert(END, i)

    print(filename2)

def forMuButton1():
    win.destroy()

def var_states():
    print("soil: %d, \nweather:%d" % (MyVar1.get(), MyVar2.get()))

MyLabel1 = Label(frame, text="Select:")
MyLabel1.grid(row=0, column=0, sticky=W)


MyVar1 = IntVar()
MyVar2 = IntVar()

MyCheckbutton1 = Checkbutton(frame, text="soil", variable=MyVar1, command=forCheckbutton1)
MyCheckbutton1.grid(row=1, column=0, sticky=W)


MyCheckbutton2 = Checkbutton(frame, text="weather", variable=MyVar2, command=forCheckbutton2)
MyCheckbutton2.grid(row=2, column=0, sticky=W)


MyButton1 = Button(frame, text="Submit", width=10, command=forMuButton1)
MyButton1.grid(row=5, columnspan=3)

scrollbar = Scrollbar(rightframe)
scrollbar.pack( side = RIGHT, fill = Y )

myList = Listbox(rightframe, yscrollcommand = scrollbar.set )
myList.pack( side = LEFT, fill = BOTH )
scrollbar.config( command = myList.yview )

win.mainloop()
