Tkinter modify root window from TopLevel() widget - python

I am new to Tkinter/OOP and would like some help, I am currently stuck making a gui for a application. The functionality i want is that when a new window using the TopLevel() widget is spawned the button used for it to become disabled, which i have achieved. However the problem is enabling it after the spawned window is closed.
And in general how does one go about modifying the main tkinter root window from a TopLevel() widget using an OOP based approach. As i would like to do more stuff later on
The code is as follows:
from tkinter import *
from tkinter import ttk
class MainWindow:
def __init__(self, top):
_bgcolor = '#d9d9d9' # X11 color: 'gray85'
_fgcolor = '#000000' # X11 color: 'black'
_compcolor = '#d9d9d9' # X11 color: 'gray85'
_ana1color = '#d9d9d9' # X11 color: 'gray85'
_ana2color = '#d9d9d9' # X11 color: 'gray85'
font10 = "-family {Segoe UI} -size 10 -weight normal -slant " \
"roman -underline 0 -overstrike 0"
self.style = ttk.Style()
if sys.platform == "win32":
self.style.theme_use('winnative')
self.style.configure('.', background=_bgcolor)
self.style.configure('.', foreground=_fgcolor)
self.style.configure('.', font="TkDefaultFont")
self.style.map('.', background=
[('selected', _compcolor), ('active', _ana2color)])
self.top=top
self.top.geometry("214x96+462+349")
self.top.title("Test")
self.top.configure(background="#d9d9d9")
self.top.configure(highlightbackground="#d9d9d9")
self.top.configure(highlightcolor="black")
self.top.resizable(0, 0)
self.Btn_UI = Button(self.top)
self.Btn_UI.place(relx=0.50, rely=0.21, height=24, width=100)
self.Btn_UI.configure(activebackground="#d9d9d9")
self.Btn_UI.configure(activeforeground="#000000")
self.Btn_UI.configure(background="#d9d9d9")
self.Btn_UI.configure(command=self.Btn_UI_fun)
self.Btn_UI.configure(disabledforeground="#a3a3a3")
self.Btn_UI.configure(foreground="#000000")
self.Btn_UI.configure(highlightbackground="#d9d9d9")
self.Btn_UI.configure(highlightcolor="black")
self.Btn_UI.configure(pady="0")
self.Btn_UI.configure(text='''New Window''')
def Btn_UI_fun(self):
print('button')
root2 = Toplevel(self.top)
second = SettingsWindow(root2)
self.Btn_UI.configure(state="disabled")
return
class SettingsWindow():
def __init__(self, master):
self.master=master
self.master.geometry("214x96+462+349")
self.master.title("New")
self.master.configure(background="#d9d9d9")
self.master.configure(highlightbackground="#d9d9d9")
self.master.configure(highlightcolor="black")
self.master.resizable(0, 0)
self.Btn = Button(self.master)
self.Btn.place(relx=0.50, rely=0.21, height=24, width=51)
self.Btn.configure(text='''Quite''')
self.Btn.configure(command=self.quite)
def quite(self):
p = MainWindow.__init__
p.self.Btn_UI.configure(state="normal")
self.master.destroy()
def main():
root = Tk()
Main = MainWindow(root)
root.mainloop()
main()
Thanks in Advance!! :D

Created two dropdowns one is for class selection and other is for method selection of that particular class. class name: basic, advance, method selection: basic: add,sub, advance:multiply, division and modulus. currently struck at issue where i select class as basic, it shows basic in method selection dropdown also which is not inteded. thereafter if i select class as basic and in method i select add, class which has to be basic is also getting changed to add. help me out.
You have used same tkinter variable self.combobox for both Combobox widgets.
Remove the line:
self.TCombobox2.configure(textvariable=self.combobox)
Or use another tkinter variable for self.TCombobox2.

vp_start_gui()
HERE IS THE ERROR PICTURE:

Thanks
Don't use a mix of tabs and space for indentation, it's not considered a good practice (python specific).
Now to fix it:
Go to terminal and type pip install autopep8
Once it's installed type the following command :
autopep8 -i yourfilename.py
3)You're good to go now!

Pi GUI with an existing while loop

I am struggling to get a simple GUI to work with python (2.7) on Raspberry Pi (Buster).
I have tried Tkinter and PySimpleGUI but both of these effectively use while loops and I
already have such a loop in my program, which is working without issue.
Both Tkinter and PySimpleGUI block the main loop.
Attempts to run Tkinter and PySimpleGUI in a thread do not seem to work,
various elements are not thread compliant and hang with various error messages.
In any case it appears that once in a thread you can't interact with the GUI widgets
unless you create complicated queues and they are not thread safe.
All I am trying to do is write out the print 'Alert Door statement (last line of the while loop)
into a text field (something pretty / colourful)
and then have an alarm sound (GPIO) and a button which clears the alarm and text field.
Any thoughts apreciated, it appears the available Pi GUIs are just not suitable.
Be gentle, I am a newbie.

Both Tkinter and PySimpleGUI block the main loop.
This is not true always.In my experience the best solution to stop tkinter from blocking the main program's loop is using root_window.update() instead of root_window.mainloop().
Using this will allow you to keep iterating through your while loop and also update your tkinter window.
Hope this helps.
UPDATE
Following your edit I had a look at your code myself.
I changed the function vp_start_gui() and created the root window outside the loop.The main goal of this code is to give you an idea about how to go about implementing your tkinter window correctly.Also about the buttons changing the active background when hovering over it; tkinter.tk Buttons don't have this feature by default.What they really mean by active backgroud is the background color when you click the button.Though there are ways to get this done using tkinter.tk I have showed an easy way to get what you want using tkinter.ttk.

Your "blocking" problem is easily solving by running your PySimpleGUI program in "async mode". The docs have quite a bit of info about using timeouts on your read call and you'll find tons of demo programs that demonstrate this technique.
Here's a sample bit of code that loops, updating a counter every 100 milliseconds. You could add polling for a hardware condition or some set of conditions instead of updating the text. This is where you would add code to poll something.
import PySimpleGUI as sg
layout = [ [sg.Text('My Window')],
[sg.Text('Will output here', key='-OUT-')],
[sg.Button('Exit')] ]
window = sg.Window('A non-blocking window', layout)
count = 0
while True:
event, values = window.read(timeout=100) # returns every 100 milliseconds
if event == sg.WIN_CLOSED or event == 'Exit':
break
window['-OUT-'].update(f'Count={count}')
count += 1
window.close()

You can use multithreading module or thread module if you want to process multiple commands at the same time if this is the answer that you are searching for.
