I don't know how to return or print result to entry widget. I've tried to add code on the res function, but it still doesn't return the result that I want.
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()
Sorry, forgot to add this. Yes, you just need to use resultentry.insert(0, result)and you should be set. I also like using this as a good resource:

I want to update getting results from an entry box in a way that when an integer enters, the equivalent rows of entry boxes appear below that. I have written the below code to make it work using a button. However, I want to make it happen automatically without a button as I entered the number, the rows update. I checked one way of doing that is using the after(). I placed after after() in the function and out of the function but it is not working.
from tkinter import *
root = Tk()
root.geometry("400x400")
n_para = IntVar()
label1 = Label(root, text="Numeric parameters")
label1.grid(row=0, column=0)
entry1 = Entry(root, textvariable=n_para)
entry1.grid(row=0, column=1)
def update():
for i in range(1, n_para.get()+1):
entryX = Entry(root)
entryX.grid(row=i+1, column=0)
entryY = Entry(root)
entryY.grid(row=i+1, column=1)
entryZ = Entry(root)
entryZ.grid(row=i+1, column=2)
root.after(100, update)
root.after(1, update)
button1 = Button(root, text="update", command=update)
button1.grid(row=1, column=0)
root.mainloop()
You should try using the <KeyRelease> event bind.
import tkinter as tk
def on_focus_out(event):
label.configure(text=inputtxt.get())
root = tk.Tk()
label = tk.Label(root)
label.pack()
inputtxt = tk.Entry()
inputtxt.pack()
root.bind("<KeyRelease>", on_focus_out)
root.mainloop()
This types the text entered in real-time.
Edited Code with OP's requirement:
from tkinter import *
root = Tk()
root.geometry("400x400")
n_para = IntVar()
label1 = Label(root, text="Numeric parameters")
label1.grid(row=0, column=0)
entry1 = Entry(root, textvariable=n_para)
entry1.grid(row=0, column=1)
def upd(event):
x = entry1.get()
if not x.isnumeric():
x = 0
for i in range(1, int(x)+1):
entryX = Entry(root)
entryX.grid(row=i+1, column=0)
entryY = Entry(root)
entryY.grid(row=i+1, column=1)
entryZ = Entry(root)
entryZ.grid(row=i+1, column=2)
# root.after(100, update)
root.bind("<KeyRelease>", upd)
# button1 = Button(root, text="update", command=update)
# button1.grid(row=1, column=0)
root.mainloop()
a newbie here,
i have read every post that can be related to my problem but did not solve it.
i am tryin to get the input from user to a list and then show it to the user, but nothing happens.
here is the code:
from tkinter import *
root = Tk()
root.title("MyApp")
root.geometry("700x500")
my_entries = []
def something():
entry_list = ''
for entries in my_entries:
entry_list = entry_list + str(entries.get()) + '\n'
my_label.config(text=entry_list)
for x in range(3):
my_entry = Entry(root)
my_entry.grid(row=0, column=x, pady=20, padx=5)
my_button = Button(root, text="set", command=something)
my_button.grid(row=1, column=0, pady=20)
my_label = Label(root, text='Total Income')
my_label.grid(row=4, column=0, pady=20)
root.mainloop()
You didn't append the entries to my_entries. Here is what the for loop should look like:
for x in range(3):
my_entry = Entry(root)
my_entry.grid(row=0, column=x, pady=20, padx=5)
my_entries.append(my_entry)
I have one Input and one button. I want the value of the input (Entry) to when I press the button. When I type print(mtext) it works well, but when I put it in a Label it doesn't work.
Here is the code:
from tkinter import *
root = Tk()
root.title("Mohamed Atef")
root.geometry("900x600")
var = StringVar()
var.set("Please write something")
label = Label(root, textvariable=var, padx=10, pady=10)
#input
text = StringVar()
entry = Entry(root, textvariable=text)
def mohamed():
mtext = text.get()
mohamed = Label(root, textvariable=mtext)
mohamed.pack()
#button
buttonText = StringVar()
buttonText.set("Click me !")
button = Button(root, textvariable=buttonText, command=mohamed)
label.pack()
entry.pack()
button.pack()
root.mainloop()
Same as Flilp, your finished product would look like this
from tkinter import *
root = Tk()
root.title("Mohamed Atef")
root.geometry("900x600")
var = StringVar()
var.set("Please write something")
label = Label(root, textvariable=var, padx=10, pady=10)
#input
text = StringVar()
entry = Entry(root, textvariable=text)
def mohamed() :
mtext = text.get()
mohamed = Label(root, text=mtext)
mohamed.pack()
#button
buttonText = StringVar()
buttonText.set("Click me !")
button = Button(root, textvariable=buttonText, command=mohamed)
label.pack()
entry.pack()
button.pack()
root.mainloop()
If you just want text that's in your Entry to appear under your labels you could do:
def mohamed():
mohamed = Label(root, textvariable=text)
mohamed.pack()
Your code didn't work because value passed as textvariable should be tkinter StringVar() not string.
If you don't want the text to be constantly updated when you change your Entry you should do:
def mohamed():
mtext = text.get()
mohamed = Label(root, text=mtext)
mohamed.pack()
I'm trying to get the value of the radiobutton selcted and storing this int into a varable. It's my first tkinter project, so I'm sorry for my probably stupid mistakes...
from tkinter import *
from tkinter import ttk
select = "A"
def begin():
grand = Tk()
grand.title("Converter")
window.destroy()
frame = Frame(grand)
option = IntVar()
-> AttributeError: 'NoneType' object has no attribute '_root'
grandlabel = Label(frame, text="Choose the grand").grid(row=0, sticky=N, padx=5)
grand1 = Radiobutton(frame, text="Speed", variable=option, value=1, command=sel).grid(row=1, sticky=W)
grand2 = Radiobutton(frame, text="etc", variable=option, value=2, command=sel).grid(row=2, sticky=W)
submitgrand = Button(frame, text="Ok", command=unit).grid(row=3, sticky=W)
frame.pack()
grand.mainloop()
def sel():
global option
global select
select = option.get()
option = StringVar()
def unit():
unit = Tk()
global select
select = grandchosen
if (grandchosen == "Speed"):
Label(unit, text="Test").pack()
else:
Label(unit, text="Test2").pack()
unit.mainloop()
root = Tk()
frame = Frame(root)
welcome = ttk.Label(frame, text="Welcome!").grid(row=0, sticky=N, padx=10, pady=3)
okbutton = Button(frame, text="Ok", width=15, command=begin).grid(row=1, sticky=S, padx=20, pady=30)
frame.pack()
style = ttk.Style()
style.configure("TLabel", foreground="midnight blue", font="Times 19")
root.mainloop()
Would be great to get some help, thank you!
I am making a quiz in python using the tkinter module and I am stuck on how to create a button that checks to see if the answer is correct or not. But I would put it in a procedure however the question is already in one.
import tkinter as tk
window = tk.Tk()
window.title("6 Questions")
window.geometry("500x150")
score = 0
def inst():
t = tk.Label(window, text="All you need to do is just answer each question with either a '1, 2, 3' or the actual word.")
t.pack()
def start():
root = tk.Tk()
root.title("question 1")
q = tk.Label(root, text="what type of input holds whole numbers")
q.pack()
a = tk.Label(root, text="1.) int")
a.pack()
b = tk.Label(root, text="2.) string")
b.pack()
c = tk.Label(root, text="3.) float")
c.pack()
ans = tk.Entry(root, width=40)
ans.pack()
#here is the button I want to verify the answer
sub = tk.Button(root, text="Submit")
sub.pack()
greet = tk.Label(window, text="Welcome to the 6 Question Quiz.")
greet.pack()
start = tk.Button(window, command=start, text="Start")
start.pack()
instr = tk.Button(window, text="Instructions", command=inst)
instr.pack()
end = tk.Button(window, text="Exit", command=exit)
end.pack()
Create a function that opens when the submit button is clicked and create RadioButtons rather than Labels.
Like this:
def gettingDecision():
if var.get() is 'True':
messagebox.showinfo('Congrats', message='You Are Correct.Score is {}'.format(score))
else:
messagebox.showinfo('Lose', message='You Are Wrong.')
Question1 = ttk.Label(frame1, text='Q.1.Where does a computer add and compare data ?')
Question1.grid(row=1, column=0, sticky=W)
var = StringVar()
Q1A = ttk.Radiobutton(frame1, text='[A] Hard disk', variable=var, value='False1')
Q1A.grid(row=2, column=0, sticky=W)
Q1B = ttk.Radiobutton(frame1, text='[B] Floppy disk', variable=var, value='False2')
Q1B.grid(row=3, column=0, sticky=W)
Q1C = ttk.Radiobutton(frame1, text='[C] CPU chip', variable=var, value='True')
Q1C.grid(row=4, column=0, sticky=W)
Q1D = ttk.Radiobutton(frame1, text='[D] Memory chip', variable=var, value='False3')
Q1D.grid(row=5, column=0, sticky=W)
submit = ttk.Button(frame1, text='Submit', command=gettingDecision)
submit.grid()
Please note that, ideal way to go would be using classes.
You can define a function, inside of a function.
import tkinter as tk
window = tk.Tk()
window.title("6 Questions")
window.geometry("500x150")
score = 0
def inst():
t = tk.Label(window, text="All you need to do is just answer each question with either a '1, 2, 3' or the actual word.")
t.pack()
def start():
def submit():
print (ans.get())
#or do whatever you like with this
root = tk.Tk()
root.title("question 1")
q = tk.Label(root, text="what type of input holds whole numbers")
q.pack()
a = tk.Label(root, text="1.) int")
a.pack()
b = tk.Label(root, text="2.) string")
b.pack()
c = tk.Label(root, text="3.) float")
c.pack()
ans = tk.Entry(root, width=40)
ans.pack()
#here is the button I want to verify the answer
sub = tk.Button(root, text="Submit", command=submit)
sub.pack()
greet = tk.Label(window, text="Welcome to the 6 Question Quiz.")
greet.pack()
startButton = tk.Button(window, command=start, text="Start")
startButton.pack()
instr = tk.Button(window, text="Instructions", command=inst)
instr.pack()
end = tk.Button(window, text="Exit", command=window.destroy)
end.pack()
window.mainloop()
