How to update Labels in tkinter? - python

I'm trying to create a program in where you put a word in a box, press add, and this word goes to a list, which is also displayed on the right side. When I press the forward button the first thing on the list is deleted. Problem is I can't get the labels to update when I press the buttons / edit the list.
from tkinter import *
root = Tk()
root.title('Speakers List')
root.minsize(800, 600)
speakers = ['none']
spe = speakers[0]
def add():
if spe == 'none':
speakers.insert(0, [s])
e.delete(0, END)
spe.config(text=speakers[0])
else:
speakers[-2] = [s]
e.delete(0, END)
spe.config(text=speakers[0])
return
def forward():
if len(speakers) is 0:
return
else:
del speakers[0]
spe.config(text=speakers[0])
return
entry = StringVar()
e = Entry(root, width=30, font=("Arial", 20), textvariable=entry)
e.grid(row=0, sticky=W)
s = e.get()
button1 = Button(root, padx=10, pady=10, bd=5, text='Add', fg='black', command=add)
button1.grid(row=0, column=1)
button2 = Button(root, padx=10, pady=10, bd=5, text='Next', fg='black', command=forward)
button2.grid(row=1, column=1)
n = Label(root, font=("Arial", 35), bd=2, text=spe)
n.grid(row=1, sticky=W)
listdisplay = Label(root, font=('Arial', 20), text=speakers)
listdisplay.grid(row=0, column=10)
root.mainloop()

Is this the sort of thing you were looking for ?
from tkinter import *
root = Tk()
root.title('Speakers List')
root.minsize(800, 600)
speakers = ['50']
spe = speakers[0]
def add():
entry=e.get()
speakers.append(entry)
listdisplay.config(text=speakers)
return
def forward():
if len(speakers) is 0:
return
else:
del speakers[0]
listdisplay.config(text=speakers)
spe=speakers[0]
n.config(text=spe)
return
entry = StringVar()
e = Entry(root, width=30, font=("Arial", 20), textvariable=entry)
e.grid(row=0, sticky=W)
s = e.get()
button1 = Button(root, padx=10, pady=10, bd=5, text='Add', fg='black',command=add)
button1.grid(row=0, column=1)
button2 = Button(root, padx=10, pady=10, bd=5, text='Next', fg='black',command=forward)
button2.grid(row=1, column=1)
n = Label(root, font=("Arial", 35), bd=2, text=spe)
n.grid(row=1, sticky=W)
listdisplay = Label(root, font=('Arial', 20), text=speakers)
listdisplay.grid(row=0, column=10)
root.mainloop()
If so:
You create a list and then you use the append function to add an item to it. The rest was pretty much right.

How do I store user data from a Tkinter GUI form?

I tried adding a text file to store all the data by building a function that opens and writes data to the file, the code seems to run but no data is getting added to the text file.
Here is the tkinter code.
name = StringVar()
email = StringVar()
usn = StringVar()
namelabel = ttk.Label(frame_content, text='Name',font=('Poppins', 10))
namelabel.grid(row=0, column=0, sticky='sw', padx=(2,10))
entry_name = ttk.Entry(frame_content, width=30, font=('Poppins', 10), textvariable=name)
entry_name.grid(row=1, column=0)
emaillabel = ttk.Label(frame_content, text='Email',font=('Poppins', 10))
emaillabel.grid(row=0, column=1, sticky='sw', padx=10)
entry_email = ttk.Entry(frame_content, width=30, font=('Poppins', 10), textvariable=email)
entry_email.grid(row=1, column=1, padx=10)
usnlabel = ttk.Label(frame_content, text='USN',font=('Poppins', 10))
usnlabel.grid(row=0, column=2, sticky='sw')
entry_usn = ttk.Entry(frame_content, width=30, font=('Poppins', 10), textvariable=usn)
entry_usn.grid(row=1, column=2)
feedbacklabel = ttk.Label(frame_content, text='Feedback', font=('Poppins', 10))
feedbacklabel.grid(row=2, column=0, sticky='sw', pady=5)
textfeedback = Text(frame_content, width=94, height=15, font=('Poppins', 10))
textfeedback.grid(row=3, column=0, columnspan=3)
def submit():
print('Name:{}'.format(name.get()))
print('USN:{}'.format(usn.get()))
print('Email:{}'.format(email.get()))
print('Feedback:{}'.format(textfeedback.get(1.0, END)))
messagebox.showinfo(title='Submit', message='Thank you for your Feedback')
entry_name.delete(0, END)
entry_email.delete(0, END)
entry_usn.delete(0, END)
textfeedback.delete(1.0, END)
def open_file():
name_info = name.get()
email_info = email.get()
usn_info = usn.get()
feed_info = textfeedback.get(1.0, END)
data_file = open("data.txt", 'w')
data_file.write(name_info)
data_file.write(email_info)
data_file.write(usn_info)
data_file.write(feed_info)
data_file.close()
submitbutton = ttk.Button(root, width=25, text='Submit', command=lambda: [submit(), open_file()])
mainloop()
EDIT
Your mistake can be at
submitbutton = ttk.Button(root, width=25, text='Submit', command=lambda: [submit(), open_file()])
Call open_file() function first, then call submit() function, like:
submitbutton = ttk.Button(root, width=25, text='Submit', command=lambda: [open_file(), submit()])

tkinter clickable Label to open details of Label [duplicate]

This question already has answers here:
tkinter creating buttons in for loop passing command arguments
(3 answers)
Closed 6 months ago.
I'm trying to program an interface with tkinter, that shows users of my application as a list of Labels. The list is created from a database (created with sqlite3).
By clicking on each Label the program should open another window, showing details of the clicked user.
maybe do I need to use classes? (because for now, my script is not OOP)

here is the section i am confused about and would like some help with.

if int(self.Total_Maccas_num) > 5:
self.TooMany.grid(row=20, column=1)
else:
self.Total_Maccas_num(row=20, column=1)
if anyone can solve this problem it would help a lot thanks.
Inside Maccas_Submit(), you have changed self.Total_Maccas_num from IntVar (initialized inside init_window()) to int:
def Maccas_Submit(self):
# below line changed self.Total_Maccas_num to 'int'
self.Total_Maccas_num = int(self.BigMac_num.get()) + int(self.Nuggets_num.get()) + int(self.AngusBurger_num.get()) + int(self.Wraps_num.get()) + int(self.SoftServe_num.get()) + int(self.Fillet_o_Fish_num.get()) + int(self.HappyMeal_num.get()) + int(self.Salad_num.get()) + int(self.Sprite_num.get()) + int(self.Frozen_Coke_num.get()) + int(self.Apple_Pie_num.get()) + int(self.Apple_Slices_num.get())
if int(self.Total_Maccas_num) > 5:
self.TooMany.grid(row=20, column=1)
else:
# below line tries to use 'int' as a function which causes the exception
self.Total_Maccas_num(row=20, column=1)
Based on your code, I would suggest the following changes:
class Window(Frame):
...
def init_window(self):
...
self.Total_Maccas_num = IntVar()
Button(self, text='Finish Order',fg='#27251F',bg='#DA291C', command=self.Maccas_Submit).grid(row=16, column=0, sticky=W, pady=4, padx=5)
self.TooMany = Label(self, text = "Less than 5 items please.")
#self.TooMany.grid_remove() # not necessary
self.total_label = Label(self, textvariable=self.Total_Maccas_num) # added a label for the total
def Maccas_Submit(self):
total = int(self.BigMac_num.get()) + int(self.Nuggets_num.get()) + int(self.AngusBurger_num.get()) + int(self.Wraps_num.get()) + int(self.SoftServe_num.get()) + int(self.Fillet_o_Fish_num.get()) + int(self.HappyMeal_num.get()) + int(self.Salad_num.get()) + int(self.Sprite_num.get()) + int(self.Frozen_Coke_num.get()) + int(self.Apple_Pie_num.get()) + int(self.Apple_Slices_num.get())
if total > 5:
self.total_label.grid_forget() # hide the total_label
self.TooMany.grid(row=20, column=1) # show the warning
else:
self.TooMany.grid_forget() # hide the warning
self.Total_Maccas_num.set(total) # update total_label
self.total_label.grid(row=20, column=1) # show total_label

win.mainloop()
In this code I want that when I select radiobutton number, only enter a number should appear and same for the other.
But the problem is that when I select number after selecting alphabet, it shows both. I need only the selected one and eliminate the other instantly.
This is how I would approach this issue:
from tkinter import Tk, StringVar, Label, Frame, Entry, Radiobutton
def print1_selection():
for widget in entry_frame.winfo_children():
widget.destroy()
value = var.get()
lbl.config(text='You have selected ' + value)
if value == "Number":
Label(entry_frame, text="Enter a number").grid(row=0, column=0)
Entry(entry_frame).grid(row=0, column=1)
elif value == "Alphabet":
Label(entry_frame, text="Enter an alphabet").grid(row=0, column=0)
Entry(entry_frame).grid(row=0, column=1)
win = Tk()
var = StringVar(value=0)
entry_frame = Frame(win)
entry_frame.grid(row=2, column=0, columnspan=2)
lbl = Label(win, bg='white', width=20)
lbl.grid(row=3, column=0, columnspan=2, padx=10, pady=10, sticky='w')
Label(win, text="Select One", bg="crimson", fg="white", font=("times new roman", 15, "bold")).grid(row=0, column=0, padx=10, pady=10, sticky='w')
Radiobutton(win, text='Number', variable=var, value='Number', command=print1_selection, width=22).grid(row=1, column=0, padx=10, pady=10)
Radiobutton(win, text='Alphabet', variable=var, value='Alphabet', command=print1_selection, width=22).grid(row=1, column=1, padx=10, pady=10)
win.mainloop()
As You can see if You don't plan on using the widgets instance anywhere You don't have to assign it to a variable. Also no need to configure label in both statements since that will be done anyways so just do it at the beginning, also rows start from 0 too. Frames help with organizing widgets. Also if You want neither of the radiobuttons selected set the variable to 0.

Python tkinter, clearing an Entry widget from a class

This is the class I'm calling and the function from a different file
class CalcFunc:
def clearScreen(self):
self.log("CLEAR (CE)")
ent.delete(0, END)
This is the Entry Box
ent = Entry(root, textvariable=clc.getBtn, justify=RIGHT, font=10, relief=RIDGE, bd=2, width=15)
ent.grid(row=0, columnspan=3, pady=10)
This is the button I'm clicking to clear the Entry Box
buttonCC = Button(root, text="CLEAR (CE)", height=1, width=20, bg='orange', command=clc.clearScreen)
I'm not sure what the syntax is to be able to to clear an Entry widget from a class basically. That code worked when I had it in the same file but my project requires it to be in a separate file. It's a class project for a calculator and the "clear" button clears the Entry widget. I can post my entire code if that helps. Thank you.
----EDIT----
My Class
import time
class CalcFunc:
def log(self, val):
myFile = open(r".\log.dat", "a")
myFile.write("%s\n" % val)
myFile.close()
def onScreen(self, iVal):
self.log(iVal)
currentTxt = self.getBtn.get()
updateEnt = self.getBtn.set(currentTxt + iVal)
def clearScreen(self):
self.log("CLEAR (CE)")
ent.delete(0, END)
def evaL(self):
self.log("=")
self.getBtn.set(str(eval(self.getBtn.get())))
self.log(self.getBtn.get())
def logLbl(self):
myFile = open(r".\log.dat", "a")
myFile.write("\n==================================\n")
myFile.write("Date: " + str(time.strftime("%m/%d/%Y")) + " -- Time: " + str(time.strftime("%I:%M:%S")))
myFile.write("\n==================================\n")
myFile.close()

clc = clcClass.CalcFunc(ent)
class CalcFunc:
def __init__(self, entry):
self.entry = entry
def clearScreen(self):
self.log("CLEAR (CE)")
self.entry.delete(0, END)
Here's an abbreviated example:
#my_entry.py
from tkinter import END
import time
class EntryWithLogger:
def __init__(self, entry):
self.entry = entry
def log(self, val):
with open("log.dat", "a") as my_file: #Automatically closes the file--even if an exception occurs, which is not the case with my_file.close().
my_file.write("%s\n" % val)
def onScreen(self, i_val):
self.log(i_val)
self.entry.insert(END, i_val)
def clearScreen(self):
self.log("CLEAR (CE)")
self.entry.delete(0, END)
Note that I didn't use a StringVar(), which doesn't appear to be necessary. If you need it, you can always pass it as an argument to __init__(), then store it on self.
import my_entry as me
import tkinter as tk
root = tk.Tk()
root.title("Calculator")
root.geometry("+100+50") #("300x500+200+10") dimension, position
entry = tk.Entry(root, justify=tk.RIGHT, font=10, relief=tk.RIDGE, bd=2, width=15)
entry.grid(row=0, columnspan=3, pady=10)
entry_with_logger = me.EntryWithLogger(entry)
#Create the buttons in a loop:
for i in range(10):
row_num, col_num = divmod(i, 3) #divmod(7, 2) => (3, 1), divmod(0, 3) => (0, 0), divmod(4, 3) => (1, 1)
row_num += 1
button_text = str(i)
tk.Button(root, text=button_text,
height=1,
width=5,
bg='light blue',
command=lambda x=button_text: entry_with_logger.onScreen(x)
).grid(row=row_num, column=col_num, pady=5)
#Put the clear button at the bottom of the grid:
tk.Button(root, text="CLEAR (CE)",
height=1,
width=20,
bg='orange',
command=entry_with_logger.clearScreen
).grid(row=row_num+1, columnspan=3) #columnspan tells grid() to use 3 cells for the button,
#and the button will be centered by default.
root.mainloop()
Or, you could do it like this:
#my_entry.py
from tkinter import Entry, END
import time
class EntryWithLogger(Entry):
#Because __init__() is not implemented, the parent class's __init__() gets
#called, so you create an EntryWithLogger just like you would an Entry.
def log(self, val):
with open("log.dat", "a") as my_file: #Automatically closes the file--even if there is an exception, which is not the case with my_file.close().
my_file.write("%s\n" % val)
def onScreen(self, i_val):
self.log(i_val)
self.insert(END, i_val)
def clearScreen(self):
self.log("CLEAR (CE)")
self.delete(0, END)
import my_entry as me
import tkinter as tk
root = tk.Tk()
root.title("Calculator")
root.geometry("+100+50") #("300x500+200+10") dimension, position
entry = me.EntryWithLogger(root, justify=tk.RIGHT, font=10, relief=tk.RIDGE, bd=2, width=15)
entry.grid(row=0, columnspan=3, pady=10)
#Create the buttons in a loop:

row_num += 1
button_text = str(i)
tk.Button(root, text=button_text,
height=1,
width=5,
bg='LightBlue',
command=lambda x=button_text: entry.onScreen(x)
).grid(row=row_num, column=col_num, pady=5)
#Put the clear button at the bottom of the grid:
tk.Button(root, text="CLEAR (CE)",
