Detect OS Dark Mode from Python
This package allows to detect if the user is using Dark Mode on:
The main application of this package is to detect the Dark mode from your GUI Python application (Tkinter/wx/pyqt/qt for python (pyside)/...) and apply the needed adjustments to your interface. Darkdetect is particularly useful if your GUI library does not provide a public API for this detection (I am looking at you, Qt). In addition, this package does not depend on other modules or packages that are not already included in standard Python distributions.
import darkdetect >>> darkdetect.theme() 'Dark' >>> darkdetect.isDark() True >>> darkdetect.isLight() False
It's that easy.
You can create a dark mode switch listener daemon thread with
darkdetect.listener and pass a callback function. The function will be called with string "Dark" or "Light" when the OS switches the dark mode setting.
import threading import darkdetect # def listener(callback: typing.Callable[[str], None]) -> None: ... t = threading.Thread(target=darkdetect.listener, args=(print,)) t.daemon = True t.start()
The preferred channel is PyPI:
pip install darkdetect
Alternatively, you are free to vendor directly a copy of Darkdetect in your app. Further information on vendoring can be found here.
To enable the macOS listener, additional components are required, these can be installed via:
pip install darkdetect[macos-listener]

- This package can be installed on any operative system, but it will always return
Noneunless executed on a OS that supports Dark Mode, including older versions of macOS and Windows.
- On macOS, detection of the dark menu bar and dock option (available from macOS 10.10) is not supported.
