Every time I click on the buttons I get a error. Could anyone help me by providing a fix or telling me what the issue was because I cant see the issue.
Whenever the button is clicked it is supposed to open a new page and the side bar on the left with the buttons in should stay where they are at.

I have tested the code and the error you are getting when clicking the buttons is
ValueError: ['bg'] are not supported arguments. Look at the documentation for supported arguments.
As the error already says, bg is not a supported argument by customtkinter.
https://github.com/TomSchimansky/CustomTkinter/wiki/CTkLabel#arguments
In your specific case you have to change the two instances of bg="white" to bg_color="white".

I'm making a game based off of the periodic table with tkinter. I made the particle frame just fine, so I decided to copy the code and reuse it for the element frame, changing only the variable names. But for some reason, even though the particle frame works just fine, nothing shows up for the element frame. Here is my full code:
# Boilerplate
import random
import periodictable as pt
from tkinter import *
root = Tk()
root.title('Periodic Table Game')
root.geometry('350x250')
LightBlue = "#b3c7d6"
Menu = Frame(root)
elementFrame = Frame(root)
particleFrame = Frame(root)
settingsFrame = Frame(root)
root.grid_rowconfigure(0, weight=1)
root.grid_columnconfigure(0, weight=1)
for AllFrames in (Menu, elementFrame, particleFrame, settingsFrame):
AllFrames.grid(row=0, column=0, sticky='nsew')
AllFrames.configure(bg=LightBlue)
def show_frame(frame):
frame.tkraise()
show_frame(Menu)
# Menu Frame
Menu.grid_columnconfigure(0, weight=1)
root.grid_rowconfigure(0, weight=1)
root.grid_columnconfigure(0, weight=1)
MenuTitle = Label(Menu, text="Periodic Table Game", font=("Arial", 15), bg=LightBlue)
MenuTitle.grid(row=0, column=0, pady=25)
MenuTitle.grid_rowconfigure(1, weight=1)
MenuTitle.grid_columnconfigure(1, weight=1)
MenuButton1 = Button(Menu, width=25, text="Guess The Particles", command=lambda: show_frame(particleFrame))
MenuButton1.grid(row=1, column=0)
MenuButton2 = Button(Menu, width=25, text="Guess The Element Name", command=lambda: show_frame(elementFrame))
MenuButton2.grid(row=2, column=0, pady=5)
SettingsButton = Button(Menu, width=25, text="Settings", command=lambda: show_frame(settingsFrame))
SettingsButton.grid(row=3, column=0)
# Particle Frame
particleFrame.grid_columnconfigure(0, weight=1)
BackButtonF2 = Button(particleFrame, text='Back', command=lambda: show_frame(Menu))
BackButtonF2.grid(row=0, column=0, sticky=W)
ParticleLabel = Label(particleFrame, text='testing', bg=LightBlue)
ParticleLabel.grid(row=1, column=0, pady=15)
ParticleEntry = Entry(particleFrame)
ParticleEntry.grid(row=2, column=0, pady=10)
ParticleEnter = Button(particleFrame, text='Enter', width=10)
ParticleEnter.grid(row=3, column=0, pady=10)
# Element Frame
elementFrame.grid_columnconfigure(0, weight=1)
BackButtonF3 = Button(particleFrame, text='Back', command=lambda: show_frame(Menu))
BackButtonF3.grid(row=0, column=0, sticky=W)
ElementLabel = Label(particleFrame, text='testing', bg=LightBlue)
ElementLabel.grid(row=1, column=0, pady=15)
ElementEntry = Entry(particleFrame)
ElementEntry.grid(row=2, column=0, pady=10)
ElementEnter = Button(particleFrame, text='Enter', width=10)
ElementEnter.grid(row=3, column=0, pady=10)
root.mainloop()
Why does identical code work only with one frame?
Precisely, because you copied the code you don't spot where the issue is.
When you are defining the element frame widgets you are placing them all into particleFrame.
Example:
BackButtonF3 = Button(particleFrame, text='Back', command=lambda: show_frame(Menu))
should be
BackButtonF3 = Button(elementFrame, text='Back', command=lambda: show_frame(Menu))
Your problem will be solved.
Change this particleFrame, to elementFrame
snippet code:
BackButtonF3 = Button(elementFrame, text='Back', command=lambda: show_frame(Menu))
BackButtonF3.grid(row=0, column=0, sticky=W)
ElementLabel = Label(elementFrame, text='testing', bg=LightBlue)
ElementLabel.grid(row=1, column=0, pady=15)
ElementEntry = Entry(elementFrame)
ElementEntry.grid(row=2, column=0, pady=10)
ElementEnter = Button(elementFrame, text='Enter', width=10)
ElementEnter.grid(row=3, column=0, pady=10)

This might be a noob question.
But I have been raking my head on trying to enable the checkbox based on the radiobutton.
What I did is create a multiple checkboxes based on the array which is dc_ma1 and make it into the disable state. The radio button will enable or disable the checkboxes based on the user choice.
Below are some of the code:
from tkinter import *
import customtkinter
customtkinter.set_appearance_mode("System") # Modes: "System" (standard), "Dark", "Light"
customtkinter.set_default_color_theme("blue") # Themes: "blue" (standard), "green", "dark-blue"
root = customtkinter.CTk()
root.minsize(300, 300)
dc_ma1 = ["7190", "7189", "6264", "6262"]
dc_ma1_l=[str(i) for i in range(len(dc_ma1))]
print (dc_ma1_l)
selected_dc=[]
root.grid_columnconfigure(0, weight=1)
root.grid_rowconfigure(0, weight=0)
frame_lower_left = customtkinter.CTkFrame(master=root, corner_radius= 0)
frame_lower_left.grid(row=1, column=0, sticky="nswe", padx=20, pady=20)
frame_lower_left.rowconfigure((0, 1, 3 , 4), weight=0)
frame_lower_left.columnconfigure((0, 1, 2, 3, 4, 5), weight=1)
def cb_state():
print (str(radio_CB.get()))
if radio_CB.get() == 1:
print("radio is 1")
for x in range(len(dc_ma1)):
#print(dc_ma1)
check_CB1.configure(state="normal")
else:
print("radio is 0")
frame_radio = customtkinter.CTkFrame(master=frame_lower_left)
frame_radio.grid(row=0, column=0, columnspan=6, pady=20, padx=20, sticky="nsew")
frame_cb = customtkinter.CTkFrame(master= frame_lower_left)
frame_cb.grid(row=1, column=0, columnspan = 6, pady=20, padx=20, sticky="nsew")
frame_cb.pack_forget()
frame_cb.grid_columnconfigure(4, minsize=10) # empty row with minsize as spacing
frame_cb.columnconfigure(4, weight=1)
# radio button to Disable and disable CB
radio_CB = IntVar(value=0)
label_radio_group = customtkinter.CTkLabel(master=frame_radio, text="Combiner Box Configuration:")
label_radio_group.grid(row=0, column=0, pady=10, padx=10, sticky="w", columnspan = 5)
radio_button_1 = customtkinter.CTkRadioButton(master=frame_radio, variable=radio_CB, value=0, command=cb_state, text= "Disable Checkbox")
radio_button_1.grid(row=0, column=10, pady=20, padx=10, sticky="w", columnspan = 5)
radio_button_2 = customtkinter.CTkRadioButton(master=frame_radio, variable=radio_CB, value=1, command=cb_state, text="Enable Checkbox")
radio_button_2.grid(row=0, column=20, pady=20, padx=10, sticky="w", columnspan = 5)
for x in range(len(dc_ma1)):
dc_ma1_l[x]=IntVar(0)
#print(dc_ma1_l)
y=dc_ma1_l[x]
check_CB1 = customtkinter.CTkCheckBox(master= frame_cb, text="CB " + str(x+1), variable=dc_ma1_l[x],offvalue=0,onvalue=1, command=lambda x=dc_ma1[x],y=dc_ma1_l[x]:add_remove(x,y))
check_CB1.grid(row=2, column=x, pady=10, padx=10, sticky="nsew")
check_CB1.configure(state="disabled")
root.mainloop()
When I tried to Enable the checkbox it only enable the last checkbox. What did I do wrong?
Just to add, this the working code based on the comment here.
As per highlighted by #acw1668 I need to to use a list or dictionary to store those references of checkboxes:
from tkinter import *
import customtkinter

There are four buttons that hide or show a canvas. When I clicked the first time it work but then I don't really know it doesn't work.

I have implemented a code to make GUI using Tkinter and I'm new in this. The problem which I'm facing is that there is lots of spacing between two buttons in column 3 ( select object and play button).
I want to know that why this is happening.
my code is here:

I've already did a cool little CLI To-Do app in python, and now I'm trying to build a basic GUI around it. The main buttons, field in place, and yesterday I've figured out how to redirect the return string from my Todo class to the text area.
My problem now is how to clear the text area? Currently if I press the 'View button' it's continously redirecting the text without deleting the previous output. I've tried to create a function with
self.text.delete('1.0','end') + the function with the string output, but it's not working. Can you suggest me something? Thanks in advance!
