How to get the entry text and display in another entry? - python

I just want that when I type my name inside the entry box then appears in another entry with some add text. The idea is type in the entry below and after that it showed in the big entry.I was looking for this solution, but just found place in Label. I don't want in Label. The window is more big, must drag to show the entry. There's is a picture that i use in this script:
from tkinter import *
from PIL import Image, ImageTk
root = Tk()
cat = Entry(root)
cat.place(x=48, y=25, width= 350, height=140)
user = Entry(root)
user.place(x=75, y=550)
btn = Button(root, text='START')
btn.place(x=220, y=410)
root.mainloop()
#
Ok, It works the way you told me,thank you!
But now i'm facing another problem.
The problem is when i insert the function of the game in the second window. I tested in one window and it works, but when i place the function in the second window gives an error when i press the "Start" button:
'''user_try = int(txt.get())
NameError: name 'txt' is not defined'''
When i press reset button gives another error:
'''user_try = int(txt.get())
NameError: name 'txt' is not defined'''
So i know that is missing definition, but i don't know how to make a reference for this command that it's in the second window. Like i said running with just one window the program works.
Maybe i should make using class, i don't know, but i wish to make this way that i started. However if there's no other way to do as i'm doing, let's go.
I just simplify the script here, actualy the main script is more bigger, so my idea is when open the program, there is a window and the user read the instructions about the game and proceed open the second window. The window have pictures and some hidden buttons in the next picture, so there will be an interactivity with the environment.
The guess number is just the beggining. After that there will be new challeges.
I'm very excited doing this, but i'm stuck in this point. The part one i finished, the pictures, the hidden buttons it's exacly the way i want, but the challenge stops here in this problem.

There are multiple ways to do this in tkinter, here's a rework of your code using StringVar objects set to the textvariable properties of your Entry objects:
import tkinter as tk
def doit():
out_string.set("Hello " + in_string.get())
root = tk.Tk()
in_string = tk.StringVar()
out_string = tk.StringVar()
cat = tk.Entry(root, textvariable=in_string)
cat.place(x=20, y=25, width=100)
user = tk.Entry(root, textvariable=out_string)
user.place(x=20, y=75)
btn = tk.Button(root, text='START', command=doit)
btn.place(x=20, y=150)
root.mainloop()
Per #Mike-SMT, here's a different approach using Entry.get() and Entry.insert(). It augments the text when the user clicks the button:
import tkinter as tk
def doit():
user.insert(tk.END, cat.get())
root = tk.Tk()
cat = tk.Entry(root)
cat.place(x=20, y=25, width=100)
user = tk.Entry(root)
user.place(x=20, y=75)
user.insert(0, "Hello ")
btn = tk.Button(root, text='START', command=doit)
btn.place(x=20, y=150)
root.mainloop()
However, you'll see that subsequent button clicks keep appending the text. When working with Entry.insert(), you need to work with Entry.delete() and/or other Entry methods to properly manipulate the text.

on a button click, copy whats inside entry() and store it to a variable (tkinter)

I have two widgets to work with, a text input, and a button, both are created inside a function. What I want to happen is the user types in their name and then clicks the button to submit the answer. What I want the computer to do, is on the button press it will read whats inside the text and the save it to a variable. Once it saves it, it will print it out.
The code below is bad because it runs through the if statement immediately without the consulting of the button press.
There has to be a simpler solution. Also this may not be PEP 8 or whatever please be patient because I'm new.
import tkinter as tk
from tkinter import Tk, Label, Button
import sys
import time
import random
import threading
from tkinter import *
window = tk.Tk()
window.geometry("300x300")
window.title("GUI")
def start_screen():
reset()
start = tk.Label(window, text="start of game")
start.place(x=110,y=20)
play = Button(window, text= "play", command = start_game)
play.place(x=110,y=50)
helper = Button(window, text="help", command = help_screen)
helper.place(x=110,y=70)
def stuff():
global t
t = True
print(t)
return t
def text_handling():

t = False
reset()#clears the screen
label = Label(window, text='')
question1= "what is your name?"
label.pack()
print_slow(label, question1, 40)#prints out letters slowly
#here is the part I'm having problems with
name = Entry(window)
name.pack()
but = Button(window, text="enter", command= stuff)
but.pack()
print(t)
if t == True:
myPlayer.name = name.get()
print(myPlayer.name)
def start_game():
reset()
bt = tk.Button(window,text="Enter", bg="orange", command =
text_handling)
bt.place(x=100,y=100)

Opening a new window using tkinter button

As you can see on my code I'm trying to open a new window with a button. Window opens but welcome message isn't showing like the way that I want.
It shows Welcome PY_VAR0 PY_VAR1. But I would like to show a name.
I've tried using return command to return variables from getvalue() function but it doesn't work.
def getvalue():
name.get()
surname.get()
def newwindow():
window.destroy()
window2 = tk.Tk()
label3 = tk.Label(text="Welcome {} {}".format(name,surname)).grid()
window2.mainloop()
button = tk.Button(window,text="Submit",command=getvalue and newwindow).grid(row=3,column=1)
window.mainloop()
I would like to open a new window with a welcome message.
You have to use .get() to get value from StringVar, IntVar, etc - name.get(), surname.get()
label3 = tk.Label(text="Welcome {} {}".format(name.get(), surname.get()))
label3.grid()
And remeber: To set value you will have to use variable.set(value) instead of variable = value
BTW: you have big mistake in this line (and others)
label3 = tk.Label(..).grid(..)
It assign None to label3 because grid()/pack()/place() return None
You have to do it in two steps
label3 = tk.Label(..)
label3.grid(..)
You can use messagebox to open a new window as well as print a welcome message. it is really simple.
from tkinter import Tk, Button
# Make sure to import messagebox like this, otherwise you might get issues
import tkinter.messagebox
def messagebox():
tkinter.messagebox.showinfo('title','Welcome!')
def main():
width, height = 500, 500
root = Tk()
root.geometry(f'{width}x{height}')
root.title('My window')
button = Button(root, width=150, height=70, command=messagebox)
button.pack()
root.mainloop()
if __name__ == "__main__":
main()
Please import messagebox the way it is shown, I am not sure why but tkinter does not like other ways.
What happens when you print(name + " " + surname)?
If those variables have the correct values maybe you should try rewriting your script a couple different ways, for example:
labelText = "Welcome " + name + " " + surname
label3 = tk.Label(text=labelText)

Python Tkinter label not destroying

So I'm attempting to make a program with tkinter, and so far, things have gone somewhat as hoped, and I nearly achieved what I wanted.
But I've got a problem with destroying labels.
from tkinter import *
root = Tk()
root.geometry("500x500")
def controleerAntwoord(gekozenHeld, submit, eersteHintButton):
antwoord = entry.get()
if antwoord == gekozenHeld:
submit.destroy()
eersteHintButton.destroy()
eersteHint("destroy", button)
startspel()
def eersteHint(superheldHint, button):
hintTextLabel = Label(root, text = "First hint: ")
hintLabel = Label(root, text = superheldHint)
if superheldHint != "destroy":
hintTextLabel.pack()
hintLabel.pack()
button.destroy()
if superheldHint == "destroy":
hintTextLabel.destroy()
hintLabel.destroy()
def startspel():
entry.delete(0, 'end')
gekozenHeld = "test"
superheldHint1 = 'hey'
eersteHintButton = Button(root, text = "Give First Hint", command = lambda: eersteHint(superheldHint1, eersteHintButton))
submit = Button(root, text = "Submit Answer",foreground = "blue", command = lambda: controleerAntwoord(gekozenHeld, submit, eersteHintButton))
eersteHintButton.pack(side = BOTTOM)
entry.pack(side = BOTTOM)
submit.pack(side = BOTTOM, pady = 20)
def start_up():
name = entry.get().strip()
if name != "":
button.destroy()
giveName.destroy()
startspel()
giveName = Label(root, text="Insert your name: ")
entry = Entry(root)
button = Button(root, text="Enter", command=start_up)
entry.pack()
button.pack()
root.mainloop()
This is my current code so far, I know it looks big, but a lot of it can be ignored for this question.
As to how the program works, you enter your name and get taken to the next window.
There you can press the submit button and enter some text, as well as asking for a hint.
When you press the hint button, you get some text on the screen, and when you submit the correct answer, which in this case, is "test", the text should disappear. But it does not.
Any ideas on what I'm doing wrong?
The problem is that you're using a local variable, but expecting that local variable to somehow be remembered the second time you call the function. All your code does is create a label and then immediately destroy the one it just created. If you want it to destroy the one created earlier, you'll have to store that in a global variable.

Python's tkinter smart entry password

I want to create a password entry.
One easy solution is:
password = Entry(root, font="Verdana 22")
password.config(show="*");
but the problem is that to avoid typos, I want to show the item clicked to be visible only for a few seconds, while everything else is hidden. After a few seconds everything is hidden.
It's not easy to do exactly what you want with Tkinter, but here's something close: when you press a key it displays the whole contents of the Entry, but after one second the text is hidden again.
I developed this on Python 2; to use it on Python 3 change Tkinter to tkinter.
import Tkinter as tk
class PasswordTest(object):
''' Password Entry Demo '''
def __init__(self):
root = tk.Tk()
root.title("Password Entry Demo")
self.entry = e = tk.Entry(root)
e.pack()
e.bind("<Key>", self.entry_cb)
b = tk.Button(root, text="show", command=self.button_cb)
b.pack()
root.mainloop()
def entry_cb(self, event):
#print(`event.char`, event.keycode, event.keysym )
self.entry.config(show='')
#Hide text after 1000 milliseconds
self.entry.after(1000, lambda: self.entry.config(show='*'))
def button_cb(self):
print('Contents:', repr(self.entry.get()))
PasswordTest()
It would be tricky to only display the last char entered. You'd have to modify the displayed string manually while maintaining the real password string in a separate variable and that's a bit fiddly because the user can move the insertion point cursor at any time.
On a final note, I really don't recommend doing anything like this. Keep passwords hidden at all times! If you want to reduce the chance of typos in newly-chosen passwords, the usual practice is to make the user enter the password twice.
This a simple trick to visible the password with a checkbutton.
When it is checked the password will be visible
from Tkinter import *
from tkinter import ttk
def show_hide_psd():
if(check_var.get()):
entry_psw.config(show="")
else:
entry_psw.config(show="*")
window = Tk()
window.wm_title("Password")
window.geometry("300x100+30+30")
window.resizable(0,0)
entry_psw = Entry(window, width=30, show="*", bd=3)
entry_psw.place(x = 5, y = 25)
check_var = IntVar()
check_show_psw = Checkbutton(window, text = "Show", variable = check_var, \
onvalue = 1, offvalue = 0, height=2, \
width = 5, command = show_hide_psd)
check_show_psw.place(x = 5, y = 50)
window.mainloop()

Get the same input multiple times in python tkinter?

I am making a program to get multiple user names and store them in a XML file. The XML part works fine, but I am having trouble with the GUI. I want to be able to ask the user how many users he wants to input, then repeat an Entry that number of times. How can I do that, while maintaining a quit function? I tried:
def quitter():
exit()
quit()
quitterButton = Button(master, text="Quit", command=quitter)
mainCanvas.create_window(50, 330, window=quitterButton, tag="quitter")
num = int(raw_input("How many users are you going to put in?"))
for x in range(0,num):
#Create User entry Variable
userEnter = StringVar()
usrVar = ""
#Create enter box:
userEntryBox = Entry(master, textvariable = userEnter)
mainCanvas.create_window(250, 300, window=userEntryBox, tag="UserEnterA")
def gotInput(self):
usrVar = userEnter.get();
mainCanvas.create_text(250, 330, text="User Inputted: " + usrVar, tags="0")
mainCanvas.delete("UserEnterA")
#Bind entry box
userEntryBox.bind('<Key-Return>', gotInput)
userEntryBox.wait_window(userEntryBox)
#Create a new user element
newUsr= ET.Element('Member')
#Add element to the Root
root.append(newUsr)
#Make a sub element Name, set name
usrName = ET.SubElement(newUsr, 'Name')
usrName.text = usrVar;
...
tree.write('./output.xml')
What is the best way to go around it? I won't know the number of inputs, and I want the quit button to work at all times .
Behavior of your program is a bit unclear for me, but I try to help.
First solution: show tkinter askstring dialog num times. You can break for loop if user press Cancel button. It's not exactly what you want, but it's very easy to implement:
from tkinter import *
import tkinter.simpledialog as simpledialog
def add_users():
n = simpledialog.askinteger('', 'How many users are you going to put in?', initialvalue=1, minvalue=1, maxvalue=10)
if not n: # 'Cancel'
return
for i in range(n):
user = simpledialog.askstring('', 'User #%s from #%s' % (i+1, n))
if user is None: # 'Cancel'
return
# Do something useful
print(user)
root = Tk()
Button(root, text='Add users', command=add_users).pack(padx=50, pady=50)
Button(root, text='Quit', command=root.destroy).pack(pady=30)
root.mainloop()
Second (if you want to put entry and all new names to window with quit button):
from tkinter import *
import tkinter.simpledialog as simpledialog
class YourApp():
def __init__(self):
self.root = Tk()
Button(self.root, text='Quit', command=self.root.destroy).pack(pady=20)
self.ask_button = Button(self.root, text='Add users', command=self.add_users)
self.ask_button.pack(padx=50, pady=50)
self.root.mainloop()
def add_users(self):
self.users_count = 0
self.user_name = StringVar()
self.frame = Frame(self.root)
self.frame.pack()
self.users_count = simpledialog.askinteger('', 'How many users are you going to put in?', initialvalue=1, minvalue=1, maxvalue=10)
self.user_entry = Entry(self.frame, textvariable=self.user_name)
self.user_entry.pack(pady=10)
self.user_entry.bind('<Key-Return>', self.on_new_user)
self.user_entry.focus_set()
def on_new_user(self, event):
# your code
print(self.user_name.get())
Label(self.frame, text='User Inputted: %s' % self.user_name.get()).pack()
self.users_count -= 1
if not self.users_count:
self.user_entry.destroy()
self.user_name.set('')
YourApp()
There are three geometry managers in Tkinter: place (it's very similar to canvas in your case), grid and pack.
Canvas usually used for drawing pictures or graphs.
