Win32mica: A simple module to add the Mica effect and enable immersive dark mode on Python UI Windows
The aim of this project is to apply the Mica effect and enable immersive dark mode on python applications made with Python, like Tkinter, PyQt/PySide, WxPython, Kivy, etc.
This will work on any windows version, including the new released dev builds where the mica API is public.

python -m pip install win32mica- Windows 11
- A window set to not have a transparent background and to have extended composition enabled* (It might work with other settings, but nothing is guaranteed.)
- The hWnd (identifier) of that window. More info: what is a hWnd?
- OPTIONAL: The window must have semi-transparent widgets/controls in order to recreate the transparency effect on the controls.
- OPTIONAL: Know if Windows has dark or light mode enabled. This can be checked with the
darkdetectmodule

Those are PySide2 windows with custom widgets.
