Question

我不知道如何将结果返回或打印到条目小部件。我试图在res函数上添加代码，但是它仍然没有返回我想要的结果。

import tkinter as tk
from tkinter import *

win = tk.Tk()
win.title("Test")
win.configure(background='black')

enternumber = Label(win, text="Enter Number")
enternumber.grid(column=0, row=0)

var1 = IntVar()
txtenternumber = Entry(win, width=20, textvariable=var1)
txtenternumber.grid(column=1, row=0)

enternumber = Label(win, text="Enter Number")
enternumber.grid(column=0, row=1)

var2 = IntVar()
txtenternumber = Entry(win, width=20, textvariable=var2)
txtenternumber.grid(column=1, row=1)

def res():
    result = var1.get()*var2.get()
    #here the code i added
    resultentry.bind('<Return>', res)

#Here the button should returning result
resultbutton = Button(win, text="Ok", command=res)
resultbutton.grid(column=2, row=2)

resultlabel = Label(win,text="Result")
resultlabel.grid(column=0, row=2)

#I want result printed here
resultentry = Entry(win, width=30)
resultentry.grid(column=1,row=2)

import tkinter as tk
from tkinter import *

win = tk.Tk()
win.title("Test")
win.configure(background='black')

enternumber = Label(win, text="Enter Number")
enternumber.grid(column=0, row=0)

var1 = IntVar()
txtenternumber = Entry(win, width=20, textvariable=var1)
txtenternumber.grid(column=1, row=0)

enternumber = Label(win, text="Enter Number")
enternumber.grid(column=0, row=1)

var2 = IntVar()
txtenternumber = Entry(win, width=20, textvariable=var2)
txtenternumber.grid(column=1, row=1)

def res():
   result = var1.get()*var2.get()
   resultentry.insert(0,result)  # INSERTS RESULT INTO resultentry
   resultentry.bind('<Return>', res)

resultbutton = Button(win, text="Ok", command=res)
resultbutton.grid(column=2, row=2)

resultlabel = Label(win,text="Result")
resultlabel.grid(column=0, row=2)

resultentry = Entry(win, width=30)
resultentry.grid(column=1,row=2)

win.mainloop()

抱歉，忘记添加此内容。是的，您只需要使用resultentry.insert（0，result）并且应该被设置。我也喜欢将此作为很好的资源： https://effbot.org/tkinterbook/entry.htm
