How to change default theme with a ctk.CTkSlider because it doesn't changes the theme when doing so example: ctk.set_default_color_theme("sweetkind") or ctk.set_default_color_theme("green")
def green_sweet_slider_():
get=green_sweet_slider.get()
if get==1:
ctk.set_default_color_theme("green")
else:
ctk.set_default_color_theme('sweetkind')
green_sweet_slider=ctk.CTkSwitch(frame_bar,text='green',command=lambda:[green_sweet_slider_()])
green_sweet_slider.place(x=265,y=660)
green_sweet_slider.select()

Good point. Right now, once the widget is created the only way to change a particular component theme is by accessing its inner state with configure and changing every aspect of it. What you can do is to verify what attribute colors you want to change:

The code below is an atempt to help other people and maybe it can help to customize an element faster:

#python std
import sys
sys.path.append("/home/user/Repositories/CustomTkinter/")
import os
import json
import tkinter
#third-party
import customtkinter
from customtkinter import ThemeManager, CTkButton

# theme initialization
THEME = "sweetkind"
customtkinter.set_appearance_mode("dark")
customtkinter.set_default_color_theme(THEME)

# get theme by name
class ThemeUtl:

    @staticmethod
    def get_theme_by_name(theme_dir,theme_name : str):
        with open(os.path.join(theme_dir, f"{theme_name}.json"), "r") as f:
            return json.load(f)

class CTkButtonStyle:

    @staticmethod
    def customize(element : CTkButton, color_theme : str):

        theme_json = ThemeUtl.get_theme_by_name("/home/user/Repositories/CustomTkinter/assets/themes/", color_theme)

        element.configure(bg_color = theme_json["color"]["button"])
        # do the same for each button property
        # .........
        # element.configure(fg_color="default_theme")
        # element.configure(hover_color="default_theme")
        # element.configure(bg_active="default_theme")
        # element.configure(border_color="default_theme")
        # element.configure(border_width="default_theme")
        # element.configure(command=None)
        # element.configure(textvariable=None)
        # element.configure(width=140)
        # element.configure(height=28)
        # element.configure(corner_radius="default_theme")
        # element.configure(text_font="default_theme")
        # element.configure(text_color="default_theme")
        # element.configure(text_color_disabled="default_theme")


class App(customtkinter.CTk):

    theme = THEME

    def toggle_color(self):

        if App.theme == "sweetkind":
            App.theme = "blue"
            
        else:
            App.theme = "sweetkind"
            

    def alter_theme(self, event=None):
        self.toggle_color()
        CTkButtonStyle.customize(self.bt, App.theme)

    def __init__(self):
        super().__init__()
        self.title("Change Theme")

        self.geometry("800x600")
        self.bt = customtkinter.CTkButton(self, width=100, height=50, text="Change Theme", command=self.alter_theme)
        self.bt.place(anchor="center", relx="0.5", rely="0.5")


a = App()
a.mainloop()

Tom, what do you think about adding a new method inside the widget_base class, something like set_style ?

def set_style(self, style_state):
    pass

And then implementing inside each widget how to override the style for that individual component ?

Yeah if I have the time I will do this

Has there been any progress on this? It's really nice that the appearance mode ('dark', 'light', 'system') can be changed on the fly (e.g. with a button), but it would also be very nice to have an 'approved' way to change the theme.
Thanks a million, I love ctk
