Select a single row of a list box in PySimpleGUI

Question

My question is simple, I'm a begginer in PySimpleGUI, and I want to know how do I change the color of text in a list box, but i want to change only some specific lines, so it's important that I can run all the list and select the lines. Someone know how to do that, I'll be very thankfull.

You can change the text color for the entire list box with `text_color`. There is no way to change individual rows without going a level deeper (like to tk, but this would vary by OS, so it's not trivial.) — nycynik, Feb 26 '21 at 08:50

tkinter code required to set options for items in listbox.

import PySimpleGUI as sg

sg.theme("DarkBlue")

items = ['USA', 'Mexico', 'Japan', 'Korea', 'UK', 'China', 'France']
asia_index = (2 ,3, 5)

layout = [
    [sg.Listbox(items, size=(10, 7), key='-LISTBOX-')],
]
window = sg.Window('Title', layout, finalize=True)
listbox = window['-LISTBOX-'].Widget
for index in asia_index:
    listbox.itemconfigure(index, bg='green', fg='white')    # set options for item in listbox
while True:
    event, values = window.read()
    if event == sg.WINDOW_CLOSED:
        break
    print(event, values)

window.close()

You can change the color of a text by adding text_color='COLOR' when creating it.

for exmaple:

Sg.Text("My text", key="sub_title", size=(15, 1), text_color='yellow')

And if you want to change the color of a button you'll need to use button_color=('FIRST_COLOR', 'SECOND_COLOR') just like below:

    Sg.Button("Update", key='update_button', size=(25, 1), button_color=('blue', 'purple'))

Enjoy.
