Ive got a function that changes the theme based on the windows theme.

[jhi2]

Rdbende,
I have a function that can switch the theme based on the windows theme. For example, if Windows is in dark mode, the theme of the app will be in dark mode too. the code for this function is based on your change theme function. the code for this function is as follows:

import ctypes as ct
import darkdetect
def settheme(window):
    window.tk.call("source", "azure.tcl")
    window.tk.call("set_theme", "light")
    def dark_title_bar(window):
        """
        MORE INFO:
        https://docs.microsoft.com/en-us/windows/win32/api/dwmapi/ne-dwmapi-dwmwindowattribute
        """
        window.update()
        DWMWA_USE_IMMERSIVE_DARK_MODE = 20
        set_window_attribute = ct.windll.dwmapi.DwmSetWindowAttribute
        get_parent = ct.windll.user32.GetParent
        hwnd = get_parent(window.winfo_id())
        rendering_policy = DWMWA_USE_IMMERSIVE_DARK_MODE
        value = 2
        value = ct.c_int(value)
        set_window_attribute(hwnd, rendering_policy, ct.byref(value), ct.sizeof(value))
    def change_theme():
    # NOTE: The theme's real name is azure-<mode>
        if window.tk.call("ttk::style", "theme", "use") == "azure-dark":
            # Set light theme
            window.tk.call("set_theme", "light")
        else:
            # Set dark theme
            window.tk.call("set_theme", "dark")
    is_dark = darkdetect.isDark()
    if is_dark:
        change_theme()
        dark_title_bar(window)
