This basically creates all the frames and brings the one we call to the front right?
So as some variables change i want the frames to change accordingly, i tried a few refreshing functions i found while searching in google but none of them worked in this code.
oooooooooooooooooooooooooooooo

With the code below (that I took from sentdex) I am trying to raise PageOne window when the correct password("123") is inserted in the first page. However, I get the error: TypeError: show_frame() missing 1 required positional argument: 'cont'. Isn't PageOne the argument ? Why is not working ? Could you also please explain what "controller" variable does ?
Thank you very much in advance.

You are calling the method on the class rather than the instance, so the first argument is passes to the self parameter.
Your class needs to keep a reference to the controller, so that you can call the method via the controller.
class StartPage(tk.Frame):
def __init__(self, parent, controller):
self.controller = controller
...
def SubmitPass(self):
global Password
Password = self.entry.get()
if Password == "123":

When you select 2 duelist on the second screen the program shows a 3rd screen that should display 2 labels and 2 entry widgets for the user to enter the names of the players. But I can't seem to figure out why the widgets are not showing up. The section of code that involves this issue is the the block for the class TwoPlayer. Thank you!

I'm trying to write a program which takes the users information, like their name and stuff, on one page, and then displays these entries on another. I'm using Tkinter and I can't get their entries to display on the other page. Here's the program:
import tkinter as tk
from tkinter import ttk
#PROFILE VARS
FirstName = ('none')
#INITIALIZING
class MegaQuiz(tk.Tk):
def __init__(self, *args, **kwargs):
tk.Tk.__init__(self, *args, **kwargs)
tk.Tk.wm_title(self, "THE MEGA POP QUIZ")
container = tk.Frame(self)
container.pack(side="top", fill="both", expand=True)
container.grid_rowconfigure(0, weight=1)
container.grid_columnconfigure(0, weight=1)
self.frames = {}
for F in (ProfilePage, MainPage):
page_name = F.__name__
frame = F(parent=container, controller=self)
self.frames[page_name] = frame
frame.grid(row=0, column=0, sticky="nsew")
self.show_frame("ProfilePage")
def show_frame(self, page_name):
frame = self.frames[page_name]
frame.tkraise()
#PROFILE PAGE
class ProfilePage(tk.Frame):
def __init__(self, parent, controller):
tk.Frame.__init__(self, parent)
self.controller = controller
global FirstName
#Profile Title
profile_title = tk.Label(self, text="Create A Profile Yo")
profile_title.grid(column=0, row=2)
#FIRST NAME
Q1_title = tk.Label(self, text="First Name:")
Q1_title.grid(column=0, row=1)
FirstNameEntry = tk.Entry(self)
FirstNameEntry.grid(column=2, row=4)
FirstName = str(FirstNameEntry.get())
#NEXT BUTTON
Button1 = tk.Button(self, text="NEXT",
command = lambda: controller.show_frame("MainPage"))
Button1.grid(column=10, row=10)
#MAIN MENU PAGE
class MainPage(tk.Frame):
def __init__(self, parent, controller):
tk.Frame.__init__(self, parent)
self.controller = controller
#Play BUTTON
PlayBTN = tk.Button(self, text="PLAY", width=40)
PlayBTN.grid(column=0, row=20, sticky="nesw")
#ProfileDisplay
FirstNameDis = tk.Label(self, text=('FirstName: ' + FirstName))
FirstNameDis.grid(column=0, row=0, sticky="w")
#RUNNING PROGRAM
app = MegaQuiz()
app.mainloop()
The problem is that it displays the "FirstName: ", but doesn't display the variables FirstName, just blankness, help.
The quickest way to fix this is to move your FirstName variable to the MegaQuiz as a class attribute and then use it from there. We can change your NEXT button command to call a class method and then from that method update the FirstName variable and then also set the FirstNameDis label text from that same method.
First move the FirstName variable into your MegaQuiz class by putting this line in the __init__ section.
self.FirstName = 'none'
Then change this:
#NEXT BUTTON
Button1 = tk.Button(self, text="NEXT", command = lambda: controller.show_frame("MainPage"))
To this:
#NEXT BUTTON
Button1 = tk.Button(self, text="NEXT", command=self.next_button)
Button1.grid(column=10, row=10)
def next_button(self):
self.controller.FirstName = self.FirstNameEntry.get()
self.controller.frames["MainPage"].FirstNameDis.config(text='FirstName: ' + self.controller.FirstName)
self.controller.show_frame("MainPage")
In your MainPage change this:
self.FirstNameDis = tk.Label(self, text='FirstName: ' + FirstName)
To this:
self.FirstNameDis = tk.Label(self, text='FirstName: ' + self.controller.FirstName)
That should be all you need to fix this.
I did notice a few PEP8 issues so here is your code rewritten to provide a fix to your problem and also to rewrite some things to better follow the PEP8 guidelines.
Not sure why you are adding () to some of your string variables but it is not needed.
variable and class attribute names should be all lower case with underscores to between words.
You do not need to provide a variable name for everything. If you have a button or a label you know you will not be updating later then you can write them without the variable names.
Code:
import tkinter as tk
class MegaQuiz(tk.Tk):
def __init__(self, *args, **kwargs):
tk.Tk.__init__(self)
self.title("THE MEGA POP QUIZ")
self.first_name = 'none'
container = tk.Frame(self)
container.pack(side="top", fill="both", expand=True)
container.grid_rowconfigure(0, weight=1)
container.grid_columnconfigure(0, weight=1)
self.frames = {}
for F in (ProfilePage, MainPage):
page_name = F.__name__
frame = F(parent=container, controller=self)
self.frames[page_name] = frame
frame.grid(row=0, column=0, sticky="nsew")
self.show_frame("ProfilePage")
def show_frame(self, page_name):
frame = self.frames[page_name]
frame.tkraise()
class ProfilePage(tk.Frame):
def __init__(self, parent, controller):
tk.Frame.__init__(self, parent)
self.controller = controller

I have a problem with my code. I am unable to pass a variable to another class once a submit button is pressed in my tkinter frame.
I have followed the advice from a post already (How to access variables from different classes in tkinter?), which has helped but I still have issues.
From where to where I need these variables is commented on the code below:
import tkinter as tk
from tkinter import StringVar
LARGE_FONT = ("Verdana", 12)
class Club(tk.Tk):
def get_page(self, page_class):
return self.frames[page_class]
def __init__(self, *args, **kwargs):
tk.Tk.__init__(self, *args, **kwargs)

container.grid_rowconfigure(0, weight=1)
container.grid_columnconfigure(0, weight=1)
self.shared_data = {
"username": tk.StringVar(),
"password": tk.StringVar(),
}
self.frames = {}
for F in (Terminal, newUser, newUserSubmitButton, delUser):
frame = F(container, self)
self.frames[F] = frame
frame.grid(row=0, column=0, sticky="nsew")
self.show_frame(Terminal)
def show_frame(self, cont):
frame = self.frames[cont]
frame.tkraise()
class Terminal(tk.Frame):
def __init__(self, parent, controller):
tk.Frame.__init__(self, parent)
label = tk.Label(self, text="Welcome to the club terminal. Click the options below", font=LARGE_FONT)
label.grid(columnspan=3)
button = tk.Button(self, text="Visit new User",
command=lambda: controller.show_frame(newUser))
button.grid(row=1, column=0)
button2 = tk.Button(self, text="Visit del User",
command=lambda: controller.show_frame(delUser))
button2.grid(row=1, column=1)
class newUser(tk.Frame):
def __init__(self, parent, controller):
def submitButton():
username = self.controller.shared_data["username"].get()
print(username)
controller.show_frame(newUserSubmitButton)
##username variable from here to...
tk.Frame.__init__(self, parent)
welcomelabel = tk.Label(self, text="Add New User/s", font=LARGE_FONT)
welcomelabel.grid(columnspan=2, sticky="ew")
userNameLabel = tk.Label(self, text="Username")
userNameLabel.grid(row=1, column=0, sticky="e")
userNameEntry = tk.Entry(self, textvariable=self.controller.shared_data["username"])
userNameEntry.grid(row=1, column=1)
userMemTypeLabel = tk.Label(self, text="Membership Type")
userMemTypeLabel.grid(row=2, column=0, sticky="e")
variable = StringVar(self)
variable.set("Full")
userMemTypeMenu = tk.OptionMenu(self, variable, "Full", "Half")

newusersubmitbutton.grid(columnspan=2)
class newUserSubmitButton(tk.Frame):
def __init__(self, parent, controller):
tk.Frame.__init__(self, parent)
self.controller = controller
##username variable goes here
page1 = self.controller.get_page(newUser.submitButton)
page1.username.set("Hello, world")
print(page1)
class delUser(tk.Frame):
def __init__(self, parent, controller):
tk.Frame.__init__(self, parent)
label = tk.Label(self, text="del User!!!", font=LARGE_FONT)
label.pack(pady=10, padx=10)
button1 = tk.Button(self, text="Back to Home",
command=lambda: controller.show_frame(Terminal))
button1.pack()
button2 = tk.Button(self, text="new User",
command=lambda: controller.show_frame(newUser))
button2.pack()
app = Club()
app.title("Club Terminal")
app.iconbitmap("table.ico")
app.mainloop()
Whenever I run this code, I get an AttributeError: 'newUser' object has no attribute 'controller'.
Any help is greatly appreciated, I'll be more than happy to try any ideas out.
With regards.
There are more problems in this code, but to solve that one, add the line:
self.controller=controller
To the newUser classes __init__ function.
I'm making a multiwindow GUI in tkinter and I want to change the backgroundcolor of the gui. I've tried multiple suggested solutions and they don't work. For example root.configure(background='red'). This doesn't work either: http://www.java2s.com/Code/Python/GUI-Tk/SetFramebackgroundcolor.htm
import tkinter as tk
from tkinter import *
from tkinter import ttk
LARGE_FONT = ("Verdana", 12)
def loadmsg(msg):
popupload.fileName = filedialog.askopenfilename(filetypes=(("textfiler", ".txt"), ("Alla filer", ".*")))
class Dod(tk.Tk):
def __init__(self, *args, **kwargs):
tk.Tk.__init__(self, *args, **kwargs)
tk.Tk.wm_title(self, "GUi")
container = tk.Frame(self)
container.pack(side="top", fill="both", expand=True)
container.grid_rowconfigure(0, weight=1)
container.grid_columnconfigure(0, weight=1)
self.frames = {}
for F in (StartPage, PageOne):
frame = F(container, self)
self.frames[F] = frame
frame.grid(row=0, column=0, sticky="nsew")
self.show_frame(StartPage)
def show_frame(self, cont):
frame = self.frames[cont]
frame.tkraise()
class StartPage(tk.Frame):
def __init__(self, parent, controller):
ttk.Frame.__init__(self, parent)
label = ttk.Label(self, text="GUI", font=LARGE_FONT)
label.pack(pady=10, padx=10)
button = ttk.Button(self, text="Visit Page One",
command=lambda: controller.show_frame(PageOne))
button2 = ttk.Button(self, text="Ok",
command=lambda: controller.label2)
button.pack()
button2.pack()
class PageOne(tk.Frame):
def __init__(self, parent, controller):
tk.Frame.__init__(self, parent)
label = ttk.Label(self, text="Page One", font=LARGE_FONT)
label.pack(pady=10, padx=10)
button1 = ttk.Button(self, text="Back to Home",
command=lambda: controller.show_frame(StartPage))
button1.pack()
root = Dod()
root.geometry("800x400")
root.mainloop()
This is very easy...
All you need to do is add a container.config() argument in the init function of the class Dod(tk.Tk) after the argument container.grid_columnconfigure(0, weight=1). Then, add frame.config(bg="black") after self.frames[F]=frame inside the loop for F in (start1,start,P1,P2).[This will give black colour to all frames in the loop]
The code is as follows:
import tkinter as tk

LARGE_FONT = ("Verdana", 12)
def loadmsg(msg):
popupload.fileName = filedialog.askopenfilename(filetypes=(("textfiler", ".txt"), ("Alla filer", ".*")))
