I get this error when I insert a value in the textbox.
I want to insert the date in the textbox when selecting it.
Error: _tkinter.TclError: invalid command name ".!frame.!entry"
This is my code:
main.py
from calenderUI import *
from tkinter import *
def Dateselected():
dateSelected=tkCalender()
return str(dateSelected)
def setData():
dateSel=tkCalender()
txtBoxDate.delete(0,END)
txtBoxDate.insert(0,dateSel)
return
root=Tk()
#Frame
miFrame=Frame(root,width=1200,height=2000)
miFrame.pack()
miFrame.config(bg="black")
miLabel=Label(miFrame, text="Date: ",fg="green", bg="black", font="Comic")
miLabel.grid(row=1,column=1,padx=10,pady=10)
txtBoxDate=Entry(miFrame)
txtBoxDate.grid(row=1,column=2,padx=10,pady=10,ipadx=40,ipady=2.5)
buttonDate=Button(miFrame, text="Date",command=lambda:setData())
buttonDate.grid(row=1,column=3,padx=10,pady=10)
root.mainloop()
calenderUI.py
from tkcalendar import Calendar
from tkinter import Tk
from tkinter import ttk
def tkCalender():
def print_sel():
print(cal.selection_get())
root = Tk()
cal=Calendar(root)
cal.pack()
ttk.Button(root, text="Select",command=print_sel).pack()
root.mainloop()
if __name__ == '__tkCalender__':
tkCalender()
Waiting for your help, thanks!
Error fixed, just remove root.mainloop() and some changes to insert the date in textbox (calenderUI.py)
main.py
from calenderUI import *
from tkinter import *
def Dateselected():
dateSelected=tkCalender()
return str(dateSelected)
def setData():
dateSel=tkCalender(txtBoxDate)
root=Tk()
#Frame
miFrame=Frame(root,width=1200,height=2000)
miFrame.pack()
miFrame.config(bg="black")
miLabel=Label(miFrame, text="Date: ",fg="green", bg="black", font="Comic")
miLabel.grid(row=1,column=1,padx=10,pady=10)
txtBoxDate=Entry(miFrame)
txtBoxDate.grid(row=1,column=2,padx=10,pady=10,ipadx=40,ipady=2.5)
buttonDate=Button(miFrame, text="Date",command=setData)
buttonDate.grid(row=1,column=3,padx=10,pady=10)
root.mainloop()
calenderUI.py
from tkcalendar import Calendar
from tkinter import *
dateSelected=""
def tkCalender(e):
def print_sel():
dateSelected=str(cal.selection_get())
txtBoxDate=e.delete(0,END)
txtBoxDate=e.insert(0,dateSelected)
return dateSelected
root = Tk()
cal=Calendar(root)
cal.pack()
ttk.Button(root, text="Select",command=print_sel).pack()
return str(print_sel())
if __name__ == '__tkCalender__':
tkCalender()

I want to add a progressbar when i am calling dataExtraction function inside run and it will show the progress till the dataExtraction executed once done progressbar should automatically disappear. If anyone can suggest me how can i do that that will be great.
when I run this code for **Exemple ** then I click on the ttk entry and press enter it print ----> "ttk_entry"
But when I do the same thing to the customtkinter.CTkEntry it print **nothing **.
import customtkinter
from tkinter import *
def test(event):
if root.focus_get() == custom_entry:
print("custom_entry")
elif root.focus_get() == ttk_entry:
print("ttk_entry")
root = customtkinter.CTk()
custom_entry = customtkinter.CTkEntry(root) #CTkEntry
custom_entry.pack()
ttk_entry = Entry(root) #ttk_entry
ttk_entry.pack()
root.bind("<Return>", test)
root.mainloop()
I was expecting that it print "custom_entry" .
when i run python file kill_app its run first 2nd python file(Hb_test.py) then run 1st python on tkinter.i am using vs code and python version is 3.10
see the code below
from tkinter import*
from Lab.Hb_Test import Hba
class kill_App:
def __init__(self,root):
self.root = root
self.root.geometry("1350x700+0+0")
self.root.title("Billing Software")
bg_color = "#074463"
title = Label(self.root,text = "PATHOLAB",bd=12,relief=GROOVE,bg=bg_color,fg="white",
font = ("ALGERIAN",40),pady=2).pack(fill=X)
if __name__=="__main__":
root =Tk()
obj = kill_App(root)
root.mainloop()
****
this is my second
**
**from tkinter import*
from tkinter import ttk
class Hba:
def __init__(self,root):
self.root = root
self.root.geometry("300x70+200+200")
self.root.title("JIBAN PRABHA PATHOLAB")
bg_color = "#074463"
Hb = LabelFrame(self.root,text="BLOOD TEST",font=("ALGERIAN",15,"bold")
,fg="gold",bg=bg_color)
Hb.place(x=0,y=0)
self.hb_neu_lbl = Label(Hb,text="Hb%(sahils) Test",bg=bg_color,fg="white",font=("Bell MT",15,"bold")).grid(row=1,column=1,padx=5,pady=5)
self.hb_neu=Entry(Hb,width=10,font="BellMT 15",bd=5,relief=SUNKEN).grid(row=1,column=2,padx=5,pady=5)
root = Tk()
obj = Hba(root)
root.mainloop()**
**
When Hb_Test is imported, its code will be executed, so the last three lines in the module will create a window:
Hb_Test.py
...
# below lines will create a window
root = Tk()
obj = Hba(root)
root.mainloop()
Note that it is not recommended to create more than one instance of Tk() and execute .mainloop() more than once.
For window other than the main/root window, use Toplevel instead of Tk. For your case, I would suggest that Hba inherits from Toplevel:
import tkinter as tk
class Hba(tk.Toplevel):
def __init__(self, master=None, **kwargs):
super().__init__(master, **kwargs)
self.geometry("300x70+200+200")
self.title("JIBAN PRABHA PATHOLAB")
bg_color = "#074463"
Hb = tk.LabelFrame(self, text="BLOOD TEST", font=("ALGERIAN",15,"bold"), fg="gold", bg=bg_color)
Hb.place(x=0, y=0)
self.hb_neu_lbl = tk.Label(Hb, text="Hb%(sahils) Test", bg=bg_color, fg="white", font=("Bell MT",15,"bold"))
self.hb_neu_lbl.grid(row=1,column=1,padx=5,pady=5)
self.hb_neu = tk.Entry(Hb, width=10, font="BellMT 15", bd=5, relief=tk.SUNKEN)
self.hb_neu.grid(row=1,column=2,padx=5,pady=5)
Note that I have changed from tkinter import * to import tkinter as tk because wildcard import is not recommended as well.
Also don't write code like below:
self.hb_neu_lbl = Label(Hb,text="Hb%(sahils) Test",bg=bg_color,fg="white",font=("Bell MT",15,"bold")).grid(row=1,column=1,padx=5,pady=5)
because self.hb_neu_lbl will be None (result of .grid(...)). Code like below instead:
self.hb_neu_lbl = Label(Hb, text="Hb%(sahils) Test", bg=bg_color, fg="white", font=("Bell MT",15,"bold"))
self.hb_neu_lbl.grid(row=1,column=1,padx=5,pady=5)
i'm a new programmer and there are certainly several errors but this shouldn't be difficult to spot. I need to create a simple window with a field named "Concorrente 1:" and an entry field displayed by function named lacopertina(). I don't understand where is the error:
import tkinter as tk
from tkinter import *
from tkinter.ttk import *
from tkinter import ttk
class schermoiniziale(tk.Frame):
def lacopertina():
print(gio1)
#return (tot1)
def __init__(self):
global gio1
#tot1=0
#schermo1=Tk()
self.gio1=tk.StringVar()
lab1=ttk.Label(self, text="Concorrente 1:")
lab1.pack()
ent1=ttk.Entry(self, textvariable=self.gio1)
ent1.pack()
pulsante = ttk.Button(self, text="Inizio", textvariable=self.gio1, command=self.lacopertina)
pulsante.pack()
def main():
schermoiniziale().mainloop()
if __name__== "__main__":
main()
I would suggest you to go through some tutorials on Python OOP.
I have modified your code as below with some comment:
# avoid using wildcard import
import tkinter as tk
from tkinter import ttk
class schermoiniziale(tk.Frame):
def __init__(self, master, **kw):
# need to call __init__() of inherited class
super().__init__(master, **kw)
self.gio1 = tk.StringVar()
lab1 = ttk.Label(self, text="Concorrente 1:")
lab1.pack()
ent1 = ttk.Entry(self, textvariable=self.gio1)
ent1.pack()
# removed textvariable=self.gio1 as I think you actually don't need it
pulsante = ttk.Button(self, text="Inizio", command=self.lacopertina)
pulsante.pack()
def lacopertina(self):
# use .get() to get the content of a StringVar
print(self.gio1.get())
def main():
# need to create the root window before creating other widget
root = tk.Tk()
# pass root window as the parent of the widget
frame = schermoiniziale(root)
frame.pack()
# start the tkinter mainloop
root.mainloop()
if __name__== "__main__":
main()
after going through some stack overflow and external guides still was stuck with an odd problem thread starts but function not executing but used same type of setup in unity c# and visual studio C# windows application but works there fine any help would be appreciated

To access a global variable in python, you need to use "global var_name" in each function that needs to access it:
import tkinter
import threading
import PIL
import time
from datetime import datetime
from PIL import Image
import pyscreenshot as ImageGrab
from tkinter import *
from tkinter import messagebox
from tkinter import Tk, Label, Button, Entry
running=False
class app:
def __init__(self, master):
self.master = master
self.thread1=threading.Thread(target=self.screenshot)
master.title("Screenshot Taker")
Label(master, text="Interval between screenshots").grid(row=0,sticky=W)
self.E1=Spinbox(master, from_ = 5, to = 1000,state = "readonly")
self.E1.grid(row=0,column=2,padx=10)
Label(master, text="File prefix").grid(row=1,sticky=W)
self.E2=Entry(master)
self.E2.grid(row=1,column=2,padx=10)
self.B1=Button(master, text="start" ,command = self.start)
self.B1.grid(row=2,column=0,columnspan=3)
self.B2=Button(master, text="stop" ,command = self.stop)
self.B2.grid(row=2,column=1,columnspan=3)
def screenshot(self):
global running
while(running):
im=ImageGrab.grab()
dt_string = datetime.now().strftime("%d_%m_%Y_%H_%M_%S")
name=str(self.E2.get())+str(dt_string)
logging.debug(name)
im.save(name+".png")
time.sleep(int(self.E1.get()))
