In my script, I define the layout and window for a loading screen at the top:
loading_layout = [
[sg.Text('Loading...', font=('Helvetica', 20), justification='center')]
]
loading_window = sg.Window('My Script', loading_layout, element_justification='center', finalize=True)
loading_window.hide()
Later, I try and hide the default window and show the loading menu while another function runs, like this:
if form_events == '-SUBMIT-':
name = form_values['-NAME-']
form_window.hide()
loading_window.un_hide()
run_function(name)
loading_window.hide()
main_window.un_hide()
However, that results in a pure white unresponsive window. The code still works, but the loading window contents don't render. I tried re-arranging the order of form_window.hide() and loading_window.un_hide(), which didn't work. I also tried adding a key to the loading text and refreshing it after the window loaded, which also didn't work.
Thanks in advance.

I'm running a python (3.10.2) Tkinter GUI application on Mac OS X (12.1). The code is simply just binding the event to a Combobox to create a new page. This all works fine, but sometimes when you click on the back button, it gives me the error code "Process finished with exit code 139 (interrupted by signal 11: SIGSEGV)". I've tried multiple different combinations with no success. I've tried using entry boxes from Tkinter rather than comboboxes from ttk. This still led to the same error. I then tired using a submit button instead of a combobox widget. I never experienced the error once, but in another one of my projects I wanted to bind the enter key and have a submit button which still gave me the same error. This allowed me to determine it had something to do with event binding. Next, I changed my python version (I changed from Python 3.10.0 to Python 3.9, then I upgraded to Python 3.10.2, both of these had no impact whatsoever). After this, I played around and realized that the button command itself wasn't even executing. The button was being clicked, and this killed the code for some reason. I'm really confused about the entire situation. What makes even less sense is that sometimes it occurs and sometimes it doesn't. Some runs allow it to be successful, while others don't. The other thing that I saw with my other project was that if you ran a different command that deleted the page and created a new one, the key bind would work. All of this confused me even more than I already was.

# I made its name HomePage.root in order to make it accessible to other functions without the hassle of global and local
# I also made height and width like this in order to access them in the next function
HomePage.root = Tk()
height = HomePage.root.winfo_screenheight()
width = HomePage.root.winfo_screenwidth()
HomePage.root.geometry("%dx%d" % (width, height))
# Creating combobox and binding it to NewPage function
combo = ttk.Combobox(HomePage.root)
combo.pack()
combo.bind("<Return>",NewPage)

print("yay I entered the command")
control.destroy()

# Destroying old page and creating new page

back = Button(NewPage.window, text="back", command=lambda: Back(NewPage.window, HomePage))
back.pack(side=BOTTOM)
# Running Mainloop

I worked with my code changing and modifying it until I had an idea. Rather than setting the button command, why not bind the button with a mouse click? I tried this, and it worked!
Here is my code:

width = HomePage.root.winfo_screenwidth()
HomePage.root.geometry("%dx%d" % (width, height))

combo.pack()
combo.bind("<Return>",NewPage)

I want the tkinter window i'm creating to stop taking the program focus when it is opened but still stay on top and 'lifted' the program is simple however I cant seem to find a solution to make the window open but not take focus as im not even sure thats possible.
from tkinter import *
Window = Tk()
champ_text = Label(Window, text='hello', font="arial, 100",)
champ_text.pack()
Window.wm_attributes('-disabled', False)
Window.lift()
Window.wm_attributes("-topmost", True)
#Window.overrideredirect(True)
Window.mainloop()
Foreground = focus. In my head.
You can however decide where you want the window to open on the screen:
Window.geometry('200x200+400+400')
"200x200" is the size of the window that you open.
"+400+400" is the placement on the screen for the window.
Open the window in the foreground on the side of the screen will make it not so much in focus?
Okay, so i am using tkinter to make a GUI, i feel like the top bar looks kinda ugly so that's why i was planning to remove it and put some nice icons. I used this line of code to remove the top bar gui.overrideredirect(True) and it worked :D, but you can't move the program around the screen (it sticks to the top-left corner of the screen). Is there any other way i can do this without sticking my program to the corner? Thanks.
import requests
import tkinter as tk
#GUI Config
gui = tk.Tk()
gui.geometry('970x569')
gui.title("Zombs Royale Tools v1")
gui.resizable(False, False)
#Code below is the one i used to do this[![enter image description here][1]][1]
gui.overrideredirect(True)
#Background-image
bgImage = tk.PhotoImage(file="width.png")
background_label = tk.Label(gui, image = bgImage)
background_label.place(x=0,y=0,relwidth=1, relheight=1)
#GUI Widgets#
#Exit Button
exit_image = tk.PhotoImage(file="close.gif")
exit_button = tk.Button(gui, image=exit_image, borderwidth=0, command=gui.destroy)
exit_button.place(rely=0.01, relx=0.01)
Removing the titlebar is done with override redirect. However, this removes every window function as well. That includes moving the window around and resizing it.
This means with overrideredirect you can skip the
gui.resizable(False, False)
One thing you can do is provide more info for the window’s geometry:
gui.geometry('970x569+600+500')
The 2 last numbers provide the info regarding the positioning of your window on the desktop, in case you don’t want it to be spawned on the top left corner.
If you want to make the window movable you will have to integrate your own code. It has been discussed here before.

I want to put an image in the second window using tkinter, in the first window the code works good, but the second window shows nothing.
In this part I import necessary modules:
from tkinter import filedialog, Tk, Frame, Label, PhotoImage, Button
from PIL import Image
from tkinter import*
import tkinter as tk
Then create the principal window:
raiz = Tk()
raiz.title("ventana")
Then I create the frame and put the image in the frame:
miFrame = Frame()
miFrame.pack()
miFrame.config(width="1400", heigh=("1200"))
fondo=tk.PhotoImage(file="fondoF.png")
fondo=fondo.subsample(1,1)
label=tk.Label(miFrame,image=fondo)
label.place(x=0,y=0,relwidth=1.0,relheight=1.0)
Then a button that will call the second window function:
btn3 = Button(raiz, text="boton")
btn3.place(x=500, y=500)
btn3.config(command=abrirventana2)
Here we have the function which opens the second window and here (I guess) is where I want to put the image.
This part also has two buttons named mih which does nothing in the meantime and ok which calls the function to close the second window:
def abrirventana2():
raiz.deiconify()
ventana2=tk.Toplevel()
ventana2.geometry('500x500')
ventana2.title("ventana2")
ventana2.configure(background="white")
fondov=tk.PhotoImage(file="xxx.gif")
label1=tk.Label(ventana2,image=fondov)
label1.place(x=50,y=50,relwidth=5.0,relheight=5.0)
mensaje=tk.Label(ventana2,text="funciona")
mensaje.pack(padx=5,pady=5,ipadx=5,ipady=5,fill=tk.X)
boton1=tk.Button(ventana2,text='mih')
boton1.pack(side=tk.TOP)
boton2=tk.Button(ventana2,text='ok',command=ventana2.destroy)
boton2.pack(side=tk.TOP)
Function to close the second window:
def cerrarventana2():
ventana.destroy()
I use the mainloop to keep the window open
raiz.mainloop()
Note: I had already tried creating a frame in the second window, but it didn't work.
Apologies for my previously incorrect answer.
The reason the image is not showing is due to the fact that you did not create a reference to it. If you don't create a reference, the image is garbage collected, which doesn't remove it, but in a sense just renders a blank placeholder on the GUI.
In order to display the image correctly you need to add a reference to the image within the code that displays the image.
You therefore now have:
fondov=tk.PhotoImage(file="giphy.gif")
label1=tk.Label(ventana2,image=fondov)
label1.image = fondov
label1.pack()
(label1.image = fondov is the reference)
Sorry for the confusion there. This should work.
I am having a problem with getting tkSimpleDialog to take focus over my fullscreen window GUI. I have a GUI that I am trying to use a dialog window to use as an admin password to close the GUI (like a kiosk mode app) using root.quit(). The problems with this are that the dialog does not come in front of the parent windows if the parent windows are fullscreen. Additionally, I would like to make the tkSimpleDialog go fullscreen as well.
Here is the code for how the dialog box is being called/created using the tkSimpleDialog.py in my program:
def check_admin_password():
# use askstring here to verify password.
pass_attempt = simpledialog.askstring("Verifying access","Please enter Admin password", parent=window, show="*")
if pass_attempt == "password":
root.quit() # used whatever your instance of Tk() is here in place of root.
admin_minimize_button = Button(window, text = "Administrator", command = check_admin_password, width=35, height=12)
admin_minimize_button.grid(row=4, column=0)
I am using the following code for the parent window and I believe there is something with the overrideredirect(True) that is affecting the focus of my dialog window:
qwindow = Toplevel(root) #renames Toplevel "popup" window frame to variable "qwindow"
qwindow.title('Mission Queue') #creates title on popup window
w, h = qwindow.winfo_screenwidth(), qwindow.winfo_screenheight() #aquires dimensions from display size
qwindow.geometry("%dx%d+0+0" % (w, h)) #sets window size to aquired dimensions
qwindow.overrideredirect(True) #removes top bar and exit button from parent window frame
I have tried editing the tkSimpleDialog.py file and adding an overrideredirect(True) line however that is not working. If more information is needed, let me know. Any advice would be much appreciated. Thanks in advance.
Due to my inability to figure out a solution using tkSimpleDialog, I attempted a different approach creating my own "dialog". Unfortunately, I was still unable to get the dialog to have the entry line take focus with the screen window being set to wm_attributes('-fullscreen', 'True') and overrideredirect(True). While it would have been better to have both work; for my purposes, it will work fine to just be fullscreen in my application without overrideredirect(True). For anyone with a similar issue or wanting to see more documentation on my progress, heres the link to my other forum post: (Tkinter Entry Widget with Overrideredirect and Fullscreen).
Thanks for the help!
