I'm relatively new to Tkinter and I need help.
I have created a new window when a button is clicked from the parent window. The new window is the def new_Window. But I can't seem to get the information in the window as coded below:
from tkinter import *
from tkinter import ttk
#User Interface Code
root = Tk() #Creates the window
root.title("Quiz Game")
def new_window():
newWindow = Toplevel(root)
display = Label(newWindow, width=200, height=50)
message = Label(root, text="Welcome")
display.pack()
message.pack()
display2 = Label(root, width=100, height=30)
button1 = Button(root, text ="Continue", command=new_window, width=16,
bg="red")
message_label = Label(root, text="Click 'Continue' to begin.",
wraplength=250)
username = StringVar() #Stores the username in text
user_entry = Entry(root, textvariable=username) #Creates an entry for the
username
user_entry.pack()
display2.pack()
button1.pack()
message_label.pack()
root.mainloop()#Runs the main window loop
Thanks for your help.
You did not pack the hello label into the new window. A tip is also to use background colors to visualize labels when developing. Here is a functioning code for you. I only changed 2 lines, added foreground and background.
from tkinter import *
from tkinter import ttk
# User Interface Code
root = Tk() # Creates the window
root.title("Quiz Game")
def new_window():
newWindow = Toplevel(root)
display = Label(newWindow, width=200, height=50,bg='RED')
message = Label(newWindow, text="HEEEY",fg='BLACK',bg='GREEN')
message.pack()
display.pack()
display2 = Label(root, width=100, height=30)
button1 = Button(root, text ="Continue", command=new_window, width=16,
bg="red")
message_label = Label(root, text="Click 'Continue' to begin.",
wraplength=250)
username = StringVar() # Stores the username in text
user_entry = Entry(root, textvariable=username) # Creates an entry for the
username
user_entry.pack()
display2.pack()
button1.pack()
message_label.pack()
root.mainloop() # Runs the main window loop

I have some program of this kind of type:
from tkinter import *
def apply_text(lbl_control):
lbl_control['text'] = "This is some test!"
master = Tk()
lbl = Label(master)
btn = Button(master, text="apply", command=lambda: apply_text(lbl))
lbl.pack()
btn.pack()
mainloop()
My aim now is to copy the text of the label lbl itself without any ability to change it. I tried the following way to solve the problem:
from tkinter import *
def apply_text(lbl_control):
lbl_control.insert(0, "This is some test!")
master = Tk()
lbl = Entry(master, state="readonly")
btn = Button(master, text="apply", command=lambda: apply_text(lbl))
lbl.pack()
btn.pack()
mainloop()
because of state = "readonly" it is not possible to change the text insert of lbl anymore. For that reason nothing happens if I click on the button apply. How can I change it?
There is a simple way to do that simple first change the state of entry to normal, Then insert the text, and then change the state back to readonly.
from tkinter import *
def apply_text(lbl_control):
lbl_control['state'] = 'normal'
lbl_control.delete(0,'end')
lbl_control.insert(0, "This is some test!")
lbl_control['state'] = 'readonly'
master = Tk()
lbl = Entry(master, state="readonly")
btn = Button(master, text="apply", command=lambda: apply_text(lbl))
lbl.pack()
btn.pack()
mainloop()
There is another way to do this using textvariable.
Code:(Suggested)
from tkinter import *
def apply_text(lbl_control):
eText.set("This is some test.")
master = Tk()
eText = StringVar()
lbl = Entry(master, state="readonly",textvariable=eText)
btn = Button(master, text="apply", command=lambda: apply_text(lbl))
lbl.pack()
btn.pack()
mainloop()
I want after you write something in the entry box and then you press the button a new window to pop up and
the number that was written in the entry box to be printed in the new window as " Your height is: "value" but after many tries I still don`t understand how to do it.
my code:
import tkinter as tk
root = tk.Tk()
root.geometry("250x130")
root.resizable(False, False)
lbl = tk.Label(root, text="Input your height", font="Segoe, 11").place(x=8, y=52)
entry = tk.Entry(root,width=15).place(x=130, y=55)
btn1 = tk.Button(root, text="Enter", width=12, height=1).place(x=130, y=85) #command=entrytxt1
root.mainloop()
This is what I got:
import tkinter as tk
root = tk.Tk()
root.resizable(False, False)
def callback():
# Create a new window
new_window = tk.Toplevel()
new_window.resizable(False, False)
# `entry.get()` gets the user input
new_window_lbl = tk.Label(new_window, text="You chose: "+entry.get())
new_window_lbl.pack()
# `new_window.destroy` destroys the new window
new_window_btn = tk.Button(new_window, text="Close", command=new_window.destroy)
new_window_btn.pack()
lbl = tk.Label(root, text="Input your height", font="Segoe, 11")
lbl.grid(row=1, column=1)
entry = tk.Entry(root, width=15)
entry.grid(row=1, column=2)
btn1 = tk.Button(root, text="Enter", command=callback)
btn1.grid(row=1, column=3)
root.mainloop()
Basically when the button is clicked it calls the function named callback. It creates a new window, gets the user's input (entry.get()) and puts it in a label.
Here are the labels and buttons I am using, I want the login button to check for passwords in code, then if correct go to the next screen.
from tkinter import *
root = Tk()
# Main window of Application
root.title("Please Login")
root.geometry("300x150")
root.config(background='lightblue', borderwidth=5)
# Creating Label Widget
myLabel1 = Label(root, text="Username :", background='lightblue')
myLabel2 = Label(root, text="Password :", background='lightblue')
# Entry fields
username_1 = Entry(root)
password_1 = Entry(root, show='*')
# Putting labels onto screen
myLabel1.grid(row=0, column=0)
myLabel2.grid(row=1, column=0)
# Entry field Locations
username_1.grid(row=0, column=1)
password_1.grid(row=1, column=1)
Here i have the command quit button but having a hard time with the command for login to go to next window.
# Creating Buttons
loginButton1 = Button(root, text="Login")
cancelButton3 = Button(root, text="Cancel", command=quit)
# Putting buttons onto screen
loginButton1.grid(row=6, column=1)
cancelButton3.grid(row=7, column=1)
# New window
root.mainloop()
That is a lot for one question... I'll try to give you an idea of how you can do this though. I usually do not create a whole new window; I simply change the already existing window.
from tkinter import *
root = Tk()
# Main window of Application
root.title("Please Login")
root.geometry("300x150")
root.config(background='lightblue', borderwidth=5)
# Possible Login
possible_users = {'user1': 'user1_pass', 'user2': 'user2_pass'} # dictionary of corresponding user name and passwords
# StringVars
the_user = StringVar() # used to retrieve input from entry
the_pass = StringVar()
# Creating Label Widget
myLabel1 = Label(root, text="Username :", background='lightblue')
myLabel2 = Label(root, text="Password :", background='lightblue')
bad_pass = Label(root, text="Incorrect Username or Password")
# Entry fields
username_1 = Entry(root, textvariable=the_user)
password_1 = Entry(root, show='*', textvariable=the_pass)
# Putting labels onto screen
myLabel1.grid(row=0, column=0)
myLabel2.grid(row=1, column=0)
# Entry field Locations
username_1.grid(row=0, column=1)
password_1.grid(row=1, column=1)
def login(user):
forget_login_window()
next_window(user)
def check_login():
requested_user = the_user.get()
try:
if possible_users[requested_user] == the_pass.get():
login(requested_user)
else:
bad_pass.grid(row=2, column=1)
except KeyError:
bad_pass.grid(row=2, column=1)
loginButton1 = Button(root, text="Login", command=check_login)
cancelButton3 = Button(root, text="Cancel", command=quit)
# Putting buttons onto screen
loginButton1.grid(row=6, column=1)
cancelButton3.grid(row=7, column=1)
# New window
def forget_login_window(): # forget all the grid items.
username_1.grid_forget()
password_1.grid_forget()
myLabel1.grid_forget()
myLabel2.grid_forget()
loginButton1.grid_forget()
cancelButton3.grid_forget()
bad_pass.grid_forget()
def next_window(my_user):
root.title(my_user) # desired changes here
# you will need to create your tkinter objects (buttons, labels etc) in global and pack / grid / place them here.
root.mainloop()
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()
how do I position my label which says "Question One" in my def new_window() function. As you run it the label is being positioned at the bottom, And i want it to be applied on the top.
from tkinter import *
from tkinter import ttk
#User Interface Code
root = Tk() # Creates the window
root.title("Quiz Game")
def new_window():
newWindow = Toplevel(root)
display = Label(newWindow, width=150, height=40)
message = Label(newWindow, text="Question One", font = ("Arial", "24"))
display.pack()
message.pack()
display2 = Label(root, width=100, height=30, bg='green')
button1 = Button(root, text ="Continue", command=new_window, width=16,
bg="red")
message_label1 = Label(text="A Quiz Game", font = ("Arial", "24"), padx=40,
pady=20)
message_label2 = Label(root, text="Click 'Continue' to begin.",
wraplength=250)
display2.pack()
button1.pack()
message_label1.pack()
message_label2.pack()
root.mainloop() # Runs the main window loop
You are packing in the wrong order. Do not pack display before your message. So just swapping the order will fix the issue.
Here is the code. Replace your def new_window(): with this
def new_window():
newWindow = Toplevel()
message = Label(newWindow, text="Question One", font = ("Arial", "24"))
display = Label(newWindow, width=150, height=40)
message.pack()
display.pack()
pack method just blindly packs the widget into the window. And the next pack will be done below it if there is space. So take care of the order while packing widgets :)
