not working with PySimpleGUI
I tried :
pywinstyles.apply_style(window.TKroot, 'mica')
and :
from ctypes import windll import pywinstyles hwnd = windll.user32.GetActiveWindow() pywinstyles.change_header_color(hwnd, color="blue")

lib\site-packages\customtkinter\windows\widgets\core_widget_classes\ctk_base_class.py", line 111, in config
raise AttributeError("'config' is not implemented for CTk widgets. For consistency, always use 'configure' instead.")
AttributeError: 'config' is not implemented for CTk widgets. For consistency, always use 'configure' instead.
When I try to activate the theme change to aero for the ctk.frame object, I get this error.
This library looks just fine. If it could be used in my project it would be very good. The parts of the code I'm trying to integrate it through:
class App(ctk.CTk):
def init(self):
super().init()
root = ctk.CTk()
ctk.set_default_color_theme("green") # Themes: "blue" (standard), "green", "dark-blue"
ctk.set_appearance_mode("dark")
self.title("")
self.geometry(f"{520}x{235}")
#Creating Main Frame
self.main_frame = ctk.CTkFrame(self, width=510,height=290)
self.main_frame.grid(row=0, column=10,columnspan=10, rowspan=10, ipadx=5, ipady=0, padx=0, pady=0, sticky="nw")
self.main_frame.grid_rowconfigure(3, weight=1)
self.cancel_button = ctk.CTkButton(self.main_frame, text = "Change",font=("Arial", 15),command=self.change_style('aero'))
self.cancel_button.grid(row=5, column=5,columnspan=2, padx=5, pady=10, rowspan=1)
def change_style(self,e):
pywinstyles.apply_style(self.main_frame, e)

import customtkinter
import os
from PIL import Image
import pywinstyles

class App(customtkinter.CTk):
def init(self):
super().init()

    self.title("TASK V1")
    self.iconbitmap(r"C:\Users\musta\Downloads\New folder\bot.ico")
    self.grid_rowconfigure(1, weight=1)
    self.columnconfigure(2, weight=1)
    
    

    # create scrollable checkbox frame
    self.scrollable_checkbox_frame = ScrollableCheckBoxFrame(master=self, width=200, command=self.checkbox_frame_event,
                                                             item_list=[f"item {i}" for i in range(15)])
    self.scrollable_checkbox_frame.grid(row=1, column=0, padx=15, pady=15, sticky="ns")

#if name == "main":

app = App()
pywinstyles.apply_style(app, 'acrylic')
app.mainloop()
self.toplevel_window.focus()
not particularly the code but across all the gui's that were previously working with the acrylic window now only appear slightly grey
ever since my laptop updated to the latest windows 11 update

The accent colour being returned doesn't match with the rest of the system. Notice the difference in the button colour of my app compared to the MS Store's install button.

For example, when pywinstyles.apply_style(self, "aero") is called, the theme is installed and works. However, after that you can call another theme as much as you want by means of pywinstyles.apply_style(self, "dark"), for example.
All the code in text is available in my "changer" repository.

System: Windows 10 22H2 19045.3448
GPU: NVIDIA GeForce RTX 3060
Python:3.11.5
Enabling the "Transparency Effects" option in Personalization > Colors leads to severe lag when using transparent themes (acrylic, aero, transparent). When dragging windows, there is a significant delay, with windows gradually moving to the mouse's position. Even after releasing the mouse, the windows continue to move until they reach the final release point. Additionally, the GPU usage of the Desktop Window Manager (dwm.exe) ranges from approximately 5% to 30%.
Disabling the "Transparency Effects" option doesn't result in a noticeable difference in GPU usage by the Desktop Window Manager (dwm.exe), but the lag issue disappears.

code:

import tkinter
import pywinstyles

root = tkinter.Tk()
pywinstyles.apply_style(root, "acrylic")

root.mainloop()

Hey, So I use canvas to my app for position and things like that. Now when I use PyWinStyles it wont work because of the canavs, How do I make it part of the canvas?

when I set
root.resizable(width=False, height=False)

The style doesn't change. I'm using normal tkinter.

without using pywinstyles

after using pywinstyles

pywinstyles.apply_style(app, "aero")  # here app is CTk (root)
pywinstyles.set_opacity(app, 0.8)

• something isn't right :/

Error:

def ChangeDWMAccent(hWnd: int, attrib: int, state: int, color: str | None = None) -> None:
TypeError: unsupported operand type(s) for |: 'type' and 'NoneType'

The | operator only supports python 3.10 and newer.

Fix:

from typing import Union

def ChangeDWMAccent(hWnd: int, attrib: int, state: int, color: Union[str, None] = None) -> None:
