I'm starting to learn Tkinter library and I have a problem...
I use grid to set my window the way I want but I can't figure out how I can set the width of the entry widget the same as the text widget.
When I put the same number, I don't have the same width anyway...
Here is my code :
from tkinter import *
def click():
try:
output.delete(0.0,END)
entered_text=entry.get()
output.insert(END, entered_text)
except:
output.insert(END, "")
def reset():
output.delete(0.0,END)
entry.delete(0,END)
if __name__ == '__main__':
window = Tk()
window.title("TEST")
window.geometry("500x500")
Label (window, text="Nombre de palettes :").grid(row=0, sticky=W)
Label (window, text="Prix :").grid(row=1, sticky=W)
entry = Entry (window)
entry.grid(row=0, column=2)
output = Text(window, width=8, heigh=1, wrap=WORD)
output.grid(row=1, column=2)
accepter=Button(window, text="Accepter", width=6, command=click)
accepter.grid(row=2, column=0)
restart = Button(window, text="Reset", width=6,command=reset)
restart.grid(row=2, column=1)
fin = Button(window, text="Quitter", width=6,command=window.destroy)
fin.grid(row=2, column=2)
window.grid_columnconfigure(4, minsize=100)
window.mainloop()
Thank you in advance.
One way is to expand the widgets to fill the cell:
entry = Entry(window)
entry.grid(row=0, column=2, sticky=E+W, padx=10)
output = Text(window, width=8, heigh=1, wrap=WORD)
output.grid(row=1, column=2, sticky=E+W, padx=10)
Where sticky=E+W fills the cell horizontally, and then I add some padding padx=10 to get a distance from the cell limits.
If one of the widgets always is bigger you can let that widget determine the cell width and then just expand the other widget.

I want to take user input and output it inside GUI ...
my code
from tkinter import *
root = Tk()
root.geometry("644x344")
def printSomething():
label = Label(root, text="???")
label.grid(row=1, column=2)
ok=Label(root, text="Type your name").grid(row=2,column=1)
entryvalue = StringVar()
entry= Entry(root, textvariable=entryvalue)
entry.grid(row=2, column=2)
button = Button(root, text="Print Me", command=printSomething)
button.grid(row=3, column=2)
root.mainloop()
To get the text from an input box, use inputbox.get(). Also, don't set the ok variable to Label(root, text="Type your name").grid(row=2,column=1). This will be set as NoneType, so do
ok = Label(root, text="Type your name").grid(row=2,column=1)
ok.grid(row=2, column=1)
Here is your code:
from tkinter import *
root = Tk()
root.geometry("644x344")
def printSomething():
label = Label(root, text=entry.get())
label.grid(row=1, column=2)
ok=Label(root, text="Type your name")
ok.grid(row=2,column=1)
entryvalue = StringVar()
entry= Entry(root, textvariable=entryvalue)
entry.grid(row=2, column=2)
button = Button(root, text="Print Me", command=printSomething)
button.grid(row=3, column=2)
root.mainloop()
First thing, In order to accept and display the output on the screen you have to use either Label widget or Canvas Text. Since your code is not updating the Label widget thus I am here doing what you want to do.
First, create a Label widget in the main window,
Get the user input by using.get() method,
print and display the user input.
from tkinter import *
root = Tk()
root.geometry("644x344")
def printSomething():
label.config(text=entry.get())
ok=Label(root, text="Type your name")
ok.grid(row=2,column=1)
entryvalue = StringVar()
entry= Entry(root, textvariable=entryvalue)
entry.grid(row=2, column=2)
button = Button(root, text="Print Me", command=printSomething)
button.grid(row=3, column=2)
#Create a Label to print the Name
label= Label(root, text="", font= ('Helvetica 14 bold'), foreground= "red3")
label.grid(row=1, column=2)
root.mainloop()
What I want the frame to do is that when I click on the 'clear' button, the frame is cleaned but it does not and when I enter a string that is not valid and then a valid one, it shows traces of the past and past action. I already tried changing the Label.grid () by a Label.pack (), but it is worse since the 'animation' looks like a stack without removing any element when the 'clear' button is pressed
This is basically what would make it change
from tkinter import *
import tkinter.ttk as ttk
def clear():
area.delete(0,END)
frame.config(bd=1, relief=SUNKEN)
frame.update()
status = Label(frame)
status.grid(row=0, column=0, sticky=NSEW)
def statusVal(value):
if not value == 0:
status = Label(frame, background="#ff4242", fg="#262626", text="Cadena invalida", anchor="center")
status.grid(row=0, column=0)
frame.config(bd=1, relief=SUNKEN, background="#ff4242")
frame.update()
else:
status = Label(frame, background="#56ed42", fg="#262626", text="Cadena valida", anchor="center")
status.grid(row=0, column=0)
frame.config(bd=1, relief=SUNKEN, background="#56ed42")
frame.update()
#Test
def validation():
capture = area.get()
if capture == '1':
return statusVal(0)
else:
return statusVal(1)
root = Tk()
root.geometry("300x150+300+300")
area = Entry(root)
area.grid(row=1, column=0, columnspan=2, sticky=E+W+S+N, padx=5)
frame = Frame(root, bd=1, relief=SUNKEN)
frame.grid(row=2, column=0, padx=5, pady=5, columnspan=2, sticky=W+E+S+N)
frame.columnconfigure(0,weight=5)
frame.rowconfigure(0,weight=5)
abtn = Button(root, text="Validate", command=validation)
abtn.grid(row=1, column=3)
cbtn = Button(root, text="Clear", command=clear)
cbtn.grid(row=2, column=3, pady=5)
root.mainloop()
See if this works better. The main change was to have the status Label always exist and hide or unhide it as desired — instead of creating a new one every time the validation() function was called. I also removed the code that was explicitly updating the frame which isn't necessary.
from tkinter import *
import tkinter.ttk as ttk
def clear():
area.delete(0,END)
status.grid_remove() # Hide. but remember grid options.
def statusVal(value):
if not value == 0:
status.config(background="#ff4242", fg="#262626", text="Cadena invalida",
anchor="center")
status.grid() # Unhide
else:
status.config(background="#56ed42", fg="#262626", text="Cadena valida",
anchor="center")
status.grid() # Unhide
#Test
def validation():
capture = area.get()
if capture == '1':
statusVal(0)
else:
statusVal(1)
# Main
root = Tk()
root.geometry("300x150+300+300")
area = Entry(root)
area.grid(row=1, column=0, columnspan=2, sticky=E+W+S+N, padx=5)
frame = Frame(root, bd=1, relief=SUNKEN)
frame.grid(row=2, column=0, padx=5, pady=5, columnspan=2, sticky=W+E+S+N)
frame.columnconfigure(0,weight=5)
frame.rowconfigure(0,weight=5)
# Initialize status Label.
status = Label(frame, anchor="center")
status.grid(row=0, column=0)
status.grid_remove() # Hide it.
abtn = Button(root, text="Validate", command=validation)
abtn.grid(row=1, column=3)
cbtn = Button(root, text="Clear", command=clear)
cbtn.grid(row=2, column=3, pady=5)
root.mainloop()
Using tkinter, I wanted to make an interface containing a few buttons on the left, which would be fairly static and align with the widgets on the right fairly nicely.
On the right, I wanted an Entry widget above a Text widget, both of which would resize accordingly (the Entry widget only on the X axis).
This code accomplishes most of that, except the Text widget does not resize and the Entry widget only resizes to align with the Text widget. Upon trying to column/rowconfigure the root, the top frame resizes awkwardly.
Here's a picture of the tkinter interface from this code:
from tkinter import *
def main():
root = Tk()
root.geometry("300x400")
framet = Frame(root)
frameb = Frame(root)
framet.grid(row=0, column=0, sticky='ew')
frameb.grid(row=1, column=0, sticky='news')
button1 = Button(framet, text='one', width=8)
button1.grid(row=0, column=0)
button2 = Button(frameb, text='two', width=8)
button2.grid(row=1, column=0, sticky='n')
entry1 = Entry(framet)
entry1.grid(row=0, column=1, sticky='ew')
text1 = Text(frameb, highlightbackground='black', highlightthickness=1)
text1.grid(row=1, column=1, sticky='news')
framet.columnconfigure(1, weight=1)
if __name__ == '__main__':
main()
As you can see, the Entry and Text widgets do not resize. How could I accomplish this whilst still having the Buttons remain static, and not moving anything (only resizing)?
Would this work for you? I changed the lines with # comments, I think, I can't really remember what I did I just tryed to get it working, one problem which I'm not happy with though is the entry widget is not the same height as the button, I guess you could manually set its height but..
from tkinter import *
def main():
root = Tk()
root.grid_columnconfigure(1,weight=1) # the text and entry frames column
root.grid_rowconfigure(0,weight=1) # all frames row
buttonframe = Frame(root)
buttonframe.grid(row=0, column=0, sticky="nswe")
entry_text_frame = Frame(root)
entry_text_frame.grid(row=0, column=1, sticky="nswe")
entry_text_frame.grid_columnconfigure(0,weight=1) # the entry and text widgets column
entry_text_frame.grid_rowconfigure(1,weight=1) # the text widgets row
button1 = Button(buttonframe, text='one', width=8)
button1.grid(row=0, column=0, sticky='nswe')
button2 = Button(buttonframe, text='two', width=8)
button2.grid(row=1, column=0, sticky='nswe')
entry1 = Entry(entry_text_frame)
entry1.grid(row=0, column=0, sticky='nswe')
text1 = Text(entry_text_frame, highlightbackground='black', highlightthickness=1)
text1.grid(row=1, column=0, sticky='news')
root.geometry("300x400")
if __name__ == '__main__':
main()
I have a TKinter messagebox like the one below. I would like to change part of the message to a different color. For example in the messagebox below I would like the language to be Blue. Is this possible?
It's not possible to change such options of Tkinter Standard Dialogs. You need to create your own dialog. You'll also need to separate the text parts. I've tried to make something similar in the image that the OP has posted above:
from tkinter import *
root = Tk()
def choosefunc(option):
if option == "cancel":
print("Cancel choosen")
else:
print("OK choosen")
def popupfunc():
tl = Toplevel(root)
tl.title("Languages")
frame = Frame(tl)
frame.grid()
canvas = Canvas(frame, width=100, height=130)
canvas.grid(row=1, column=0)
imgvar = PhotoImage(file="pyrocket.png")
canvas.create_image(50,70, image=imgvar)
canvas.image = imgvar
msgbody1 = Label(frame, text="The", font=("Times New Roman", 20, "bold"))
msgbody1.grid(row=1, column=1, sticky=N)
lang = Label(frame, text="language(s)", font=("Times New Roman", 20, "bold"), fg='blue')
lang.grid(row=1, column=2, sticky=N)
msgbody2 = Label(frame, text="of this country is: Arabic", font=("Times New Roman", 20, "bold"))
msgbody2.grid(row=1, column=3, sticky=N)
cancelbttn = Button(frame, text="Cancel", command=lambda: choosefunc("cancel"), width=10)
cancelbttn.grid(row=2, column=3)
okbttn = Button(frame, text="OK", command=lambda: choosefunc("ok"), width=10)
okbttn.grid(row=2, column=4)
label = Label(root, text="Click to proceed:")
label.grid()
button = Button(root, text="Click", command=popupfunc)
button.grid()

I am in the process of learning basic Python. I am currently attempting to create a simple calculator program that only has addition and subtraction. I have one issue though. I am not sure how I would add text to my Python label upon button press. Right now, upon pressing the '1' button, my program will change the display label to the text "1". However, I want my program to add text, not set it.
For example, if I press 'button 1' 5 times, it currently will reset the label text 5 times and will result with a single 1. I want it to add the number to the label upon press, not replace.
Current Result after pressing button 5 times: 1
Requested result after pressing button 5 times: 11111
Here is my current code for the program. If anything is unclear, just ask; thanks.
from tkinter import *
window = Tk()
# Creating main label
display = Label(window, text="")
display.grid(row=0, columnspan=3)
def add_one():
display.config(text='1')
# Creating all number buttons
one = Button(window, text="1", height=10, width=10, command=add_one)
two = Button(window, text="2", height=10, width=10)
three = Button(window, text="3", height=10, width=10)
four = Button(window, text="4", height=10, width=10)
five = Button(window, text="5", height=10, width=10)
six = Button(window, text="6", height=10, width=10)
seven = Button(window, text="7", height=10, width=10)
eight = Button(window, text="8", height=10, width=10)
nine = Button(window, text="9", height=10, width=10)
zero = Button(window, text="0", height=10, width=10)
# Placing all number buttons
one.grid(row=1, column=0)
two.grid(row=1, column=1)
three.grid(row=1, column=2)
four.grid(row=2, column=0)
five.grid(row=2, column=1)
six.grid(row=2, column=2)
seven.grid(row=3, column=0)
eight.grid(row=3, column=1)
nine.grid(row=3, column=2)
# Creating all other buttons
add = Button(window, text="+", height=10, width=10)
subtract = Button(window, text="-", height=10, width=10)
equal = Button(window, text="=", height=10, width=10)
# Placing all other buttons
add.grid(row=4, column=0)
subtract.grid(row=4, column=1)
equal.grid(row=4, column=2)
window.mainloop()
You should use a StringVar for this. And your callback needs to get the current contents of the StringVar, modify it, and use the modified string to set the new value of the StringVar. Like this:
import tkinter as tk
window = tk.Tk()
# Creating main label
display_text = tk.StringVar()
display = tk.Label(window, textvariable=display_text)
display.grid(row=0, columnspan=3)
def add_one():
s = display_text.get()
s += '1'
display_text.set(s)
one = tk.Button(window, text="1", height=10, width=10, command=add_one)
one.grid(row=1, column=0)
window.mainloop()
BTW, you should try to make your program a little more compact by using for loops to create and lay out your buttons, in accordance with the DRY principle.
Also, it's not a good idea to use from tkinter import *. It imports over 130 names into your namespace, making it easy to create name collisions if you accidentally use a Tkinter name for one of your own variables or functions.
You can define add_one like the following, to first get the existing value and then append a new value to it:
def add_one():
current_value = display.cget("text")
new_value = current_value + "1"
display.config(text=new_value)
Is this what you're looking for:
from tkinter import *
root = Tk()
var = StringVar()
def f1():
var.set(" ")
var.set("1")
def f2():
var.set(" ")
var.set("2")
label = Label(root, textvariable=var)
label.pack()
button1 = Button(root, text="One", command=f1)
button1.pack()
button2 = Button(root, text="Two", command=f2)
button2.pack()
