I am writing a code for a login system using tkinter and for some reason when I run the code there are no error messages and a window pops up but without the title, buttons or labels I need.
from tkinter import *
import tkinter.messagebox
frame = Tk()
def adminlogincheck(self, master):
frame = Frame(master)
frame.pack()
if username == '123key' and password == 'key123':
accept = Label(frame, text='Login Successful')
else:
decline = Label(frame, text='Login incorrect')
mainloop()
def adminselect(self, master):
frame = Frame(master)
frame.pack()
self.button = Button(frame, text="Cancel", fg="red", command=quit)
self.button.pack(side=LEFT)
self.slogan = Button(frame, text="Proceed", command=self.adminlogin)
self.slogan.pack(side=LEFT)
mainloop()
def adminlogin(self, master):
frame = Frame(master)
frame.pack()
username_entry = Entry(frame)
password_entry = Entrey(frame)
confirm = Button(frame, text='Login', command = adminlogincheck)
loginquit = Button(frame, text='Cancel', command=quit)
mainloop()
I will add more after the login system works but does anyone know why no buttons or labels appear?
There's enough in your request to see what you're trying to accomplish, but there are many issues with the code. Here is a working model of what you appear to be working toward...
from tkinter import *
import tkinter.messagebox
class Admin:
def __init__(self, master):
self.frame = Frame(master)
self.frame.pack()
self.username = StringVar()
self.password = StringVar()
def logincheck(self):
self.clearframe()
if self.username.get() == '123key' and self.password.get() == 'key123':
accept = Label(self.frame, text='Login Successful')
accept.pack(side=LEFT)
else:
decline = Label(self.frame, text='Login incorrect')
decline.pack(side=LEFT)
def select(self):
self.clearframe()
self.button = Button(self.frame, text="Cancel", fg="red", command=quit)
self.button.pack(side=LEFT)
self.slogan = Button(self.frame, text="Proceed", command=self.adminlogin)
self.slogan.pack(side=LEFT)
def login(self):
self.clearframe()
username_entry = Entry(self.frame, textvariable=self.username)
username_entry.pack()
password_entry = Entry(self.frame, textvariable=self.password)
password_entry.pack()
confirm = Button(self.frame, text='Login', command = self.logincheck)
confirm.pack()
loginquit = Button(self.frame, text='Cancel', command=quit)
loginquit.pack()
def clearframe(self):
# Destroy all children of the class's frame.
for child in self.frame.winfo_children():
child.destroy()
root = Tk()
admin = Admin(root)
admin.login()
mainloop()

This code is supposed to ask login information from the user. Then when it enters the wrong details, it will do a popup (loginErrorWdw) with a label and a button. The button there will exit the program when pressed.
I'm trying to get the button from loginErrorWdw to appear in that window but it won't. Here's my whole block of code.
from tkinter.ttk import *
from tkinter import messagebox
import tkinter as tk
import sys
import os
class Login(Frame):
def __init__(self,master):
Frame.__init__(self,master)
self.grid()
self.loginWidgets()
def loginWidgets(self):
self.userlbl = Label(self, text="Enter username: ")
self.userlbl.grid()
self.unEntry = Entry(self)
self.unEntry.grid(row=0, column=1, sticky=W)
self.pwlbl = Label(self, text="Enter password: ")
self.pwlbl.grid(row=1, column=0, sticky=W)
self.pwEntry = Entry(self, show="*")
self.pwEntry.grid(row=1, column=1, sticky=W)
self.submitBtn = Button(self, text="LOGIN", command=self.checkLogin)
self.submitBtn.grid(row=2, column=1, sticky=W)
def loginErrorWdw(self):
err = tk.Toplevel(self)
err.title("Error")
l = tk.Label(err, text="Invalid login details! The program will exit.")
l.pack(side="top", expand=False, padx=20, pady=20)
btn=tk.Button(err, text="Ok", command=self.exitBtn)
def exitBtn(self):
os._exit(0)
#change def position
def mainWdw(self):
messagebox.showinfo('Main window','Message pop up')
def checkLogin(self):
user = self.unEntry.get()
pw = self.pwEntry.get()
if user == "admin":
if pw == "lbymf1d":
self.mainWdw()
else:
self.loginErrorWdw()
else:
self.loginErrorWdw()
# un = admin, pw = lbymf1d
#window = var
window = Tk()
window.title("Login UI")
# window size
window.geometry('700x300')
login = Login(window)
# loop for window
window.mainloop()
You forgot about btn.pack()
This is way without errors:

while execution of the above code, I'm not getting any prompt or any error.Help me out in finding the solution
You have several indention errors and typos.
I am not sure how you are not getting errors as I had to fix at least 3 errors while trying to run your code. If you are using Python's default IDLE then I would suggest upgrading to something like PyCharm or Eclipse Pydev. They will provide proper traceback errors for debugging.
I have cleaned up you code. Make sure you check spelling. You had cloumn instead of column and cloumnspan instead of columnspan. command = close will cause an error as no method or function exist called close.

I am trying to get the input of what page number the user wants. They should type in a number, and click the submit button. To test it, I just want to print whatever they typed and then close the window. I've been following: http://effbot.org/tkinterbook/entry.htm as a guide, but I am stumped.
Why does
print(temp)
not print out a number to console?
right now it prints out:
<bound method IntVar.get of <tkinter.IntVar object at 0x000001FBC85353C8>>
I've cleaned up the code a little bit:
import sys
from file import *
from page import *
from view import View
import tkinter as tk
from tkinter import *
class ViewGui:
def __init__(self):
#Included in the class, but unrelated to the question:
self._file = File("yankee.txt", 25)
self.pages = self._file.paginate()
self.initial_list = self.pages[0].readpage(self._file.fo)
self.initial_string = ''.join(self.initial_list)
# Create root
self.root = Tk()
self.root.wm_title("yankee.txt - page 1")
# Create frame for buttons
self.bframe = Frame(self.root)
self.bframe.pack(side=BOTTOM, fill=X)
self.tbutton = tk.Button(self.bframe, text="Top", command=lambda a="top": self.clicks(a)).pack(side=LEFT, expand=1, fill=X)
self.bbutton = tk.Button(self.bframe, text="Bottom", command=lambda a="bottom": self.clicks(a)).pack(side=LEFT, expand=1, fill=X)
self.ubutton = tk.Button(self.bframe, text="Up", command=lambda a="up": self.clicks(a)).pack(side=LEFT, expand=1, fill=X)
self.dbutton = tk.Button(self.bframe, text="Down", command=lambda a="down": self.clicks(a)).pack(side=LEFT, expand=1, fill=X)
self.pbutton = tk.Button(self.bframe, text="Page", command=lambda a="page": self.pageclicks()).pack(side=LEFT, expand=1, fill=X)
self.qbutton = tk.Button(self.bframe, text="Quit", command=quit).pack(side=LEFT, expand=1, fill=X)
# Create and pack Text
self.T = Text(self.root, height=35, width=60, wrap=NONE)
self.T.pack(side=TOP, fill=X)
# Create and pack Scrollbar
self.S = Scrollbar(self.root, orient=HORIZONTAL, command=self.T.xview)
self.S.pack(side=BOTTOM, fill=X)
# Attach Text to Scrollbar
self.T.insert('1.0', self.initial_string)
self.T.config(xscrollcommand=self.S.set, state=DISABLED)
self.S.config(command=self.T.xview)
def pageclicks(self):
print("pageClicks is getting called at least...")
pop = Tk()
pop.wm_title("Page Number")
pop.label = Label(pop, text="Enter a Page Number:", width=35)
pop.label.pack(side=TOP)
pop.entrytext = IntVar()
Entry(pop, textvariable=pop.entrytext).pack()
pop.submitbuttontext = StringVar()
Button(pop, text="Submit", command=lambda a=pop: self.submitted(a)).pack(side=LEFT, pady=5, padx=40)
pop.cancelbuttontext = StringVar()
Button(pop, text="Cancel", command=pop.destroy).pack(side=LEFT, pady=5, padx=40)
def submitted(self, a):
print('submitted is getting called')
temp = (a.entrytext.get)
print(temp)
def clicks(self, a):
print("you clicked clicks with the " + a)
self.root.wm_title(self._file.filename + " - Page " + self._file.buttonHandler(a))
if __name__ == "__main__":
vg = ViewGui()
vg.root.mainloop()
When you create a new window you should not use Tk(), you must use tk.Toplevel()
Must change:
pop = Tk()
to
pop = tk.Toplevel()
You should also use get(), not just get. Must change:
temp = (a.entrytext.get)
to
temp = a.entrytext.get()
Code:
def pageclicks(self):
print("pageClicks is getting called at least...")
pop = tk.Toplevel()
pop.wm_title("Page Number")
pop.label = Label(pop, text="Enter a Page Number:", width=35)
pop.label.pack(side=TOP)
pop.entrytext = IntVar()
Entry(pop, textvariable=pop.entrytext).pack()
pop.submitbuttontext = StringVar()
Button(pop, text="Submit", command=lambda a=pop: self.submitted(a)).pack(side=LEFT, pady=5, padx=40)
pop.cancelbuttontext = StringVar()
Button(pop, text="Cancel", command=pop.destroy).pack(side=LEFT, pady=5, padx=40)
def submitted(self, a):
print('submitted is getting called')
temp = a.entrytext.get()
print(temp)
Made changes to these two methods and now it is working.
def pageclicks(self):
print("pageClicks is getting called at least...")
pop = Tk()
pop.wm_title("Page Number")
pop.label = Label(pop, text="Enter a Page Number:", width=35)
pop.label.pack(side=TOP)
pop._entry = Entry(pop)
pop._entry.pack()
pop._entry.focus_set()
Button(pop, text="Submit", command=lambda a=pop: self.submitted(a)).pack(side=LEFT, pady=5, padx=40)
Button(pop, text="Cancel", command=pop.destroy).pack(side=LEFT, pady=5, padx=40)
def submitted(self, _pop):
temp = _pop._entry.get()
print(temp)
_pop.destroy()
I am writing a Password code. I need a way to put to commands into one button so that it will destroy the window and get the username and password when I click the login button. I have looked through this site and non of the methods work for me so I need clarity on what I need to do to fix this.
from tkinter import *
import tkinter.messagebox as tm
class LoginFrame(Frame):
def __init__(self, master):
super().__init__(master)
self.label_1 = Label(self, text="Username")
self.label_2 = Label(self, text="Password")
self.entry_1 = Entry(self)
self.entry_2 = Entry(self, show="*")
self.label_1.grid(row=0, sticky=E)
self.label_2.grid(row=1, sticky=E)
self.entry_1.grid(row=0, column=1)
self.entry_2.grid(row=1, column=1)
self.checkbox = Checkbutton(self, text="Keep me logged in")
self.checkbox.grid(columnspan=2)
***def destroy(self):
self.destroy()
self.logbtn = Button(self, text="Login", command = self._login_btn_clickked,)
self.logbtn.grid(columnspan=2)
self.pack()
def _login_btn_clickked(self):
username = self.entry_1.get()
password = self.entry_2.get()
if username == "jake" and password == "hey":
tm.showinfo("Login info", "Welcome Jake")
master=Tk()
def login2():
tm.showinfo("Logging in", "Logging In...")
b = Button(master, text="Enter GUI", command=login2)
b.pack()
else:
tm.showerror("Login error", "Incorrect username")***
root = Tk()
lf = LoginFrame(root)
root.mainloop()
You should never call Tk() more than once in your program. If you need additional windows, use Toplevel().
However, in your case you don't need that either. You are on the right track of destroying the frame, now you just need to initiate a new frame. We can put that logic into a Tk class:
import tkinter as tk
class Mainframe(tk.Tk):
def __init__(self):
tk.Tk.__init__(self)
self.frame = FirstFrame(self)
self.frame.pack()
def change(self, frame):
self.frame.pack_forget() # delete currrent frame
self.frame = frame(self)
self.frame.pack() # make new frame
class FirstFrame(tk.Frame):
def __init__(self, master=None, **kwargs):
tk.Frame.__init__(self, master, **kwargs)
master.title("Enter password")
master.geometry("300x200")
self.status = tk.Label(self, fg='red')
self.status.pack()
lbl = tk.Label(self, text='Enter password')
lbl.pack()
self.pwd = tk.Entry(self, show="*")
self.pwd.pack()
self.pwd.focus()
self.pwd.bind('<Return>', self.check)
btn = tk.Button(self, text="Done", command=self.check)
btn.pack()
btn = tk.Button(self, text="Cancel", command=self.quit)
btn.pack()
def check(self, event=None):
if self.pwd.get() == 'password':
self.master.change(SecondFrame)
else:
self.status.config(text="wrong password")
class SecondFrame(tk.Frame):
def __init__(self, master=None, **kwargs):
tk.Frame.__init__(self, master, **kwargs)
master.title("Main application")
master.geometry("600x400")
lbl = tk.Label(self, text='You made it to the main application')
lbl.pack()
if __name__=="__main__":
app=Mainframe()
app.mainloop()
I am not familiar with python and creating user login entry window to login to the another window. The problem is that how can I make sure that it is logged in after entering correct username and password. I could go to the window that I want to login by entering the username and password but I think the coding is still not correct. Another thing is that when the login window pop up, if the user just close the window without entering username and password, the program should just quit. However it still continues to go to the window. Below is my code.
Thank you very much in advance
