Installation Method

Last released version
pip install pyqtdarktheme -
Latest development version
pip install git+https://github.com/5yutan5/PyQtDarkTheme.git@main
Usage
import sys
from PySide6.QtWidgets import QApplication, QMainWindow, QPushButton
import qdarktheme
app = QApplication(sys.argv)
# Apply the complete dark theme to your Qt App.
qdarktheme.setup_theme()
main_win = QMainWindow()
push_button = QPushButton("PyQtDarkTheme!!")
main_win.setCentralWidget(push_button)
main_win.show()
app.exec()
Further information can be found in our docs:
Enable HiDPI
# enable_hi_dpi() must be called before the instantiation of QApplication.
qdarktheme.enable_hi_dpi()
app = QApplication(sys.argv)
qdarktheme.setup_theme()
For Qt6 bindings, HiDPI “just works” without using this function.
Light theme
qdarktheme.setup_theme("light")
Sync with OS's theme and accent
qdarktheme.setup_theme("auto")

On macOS, qdarktheme also syncs with accent colors.

Customizing colors
You can customize the theme color.
# Customize accent color.
qdarktheme.setup_theme(custom_colors={"primary": "#D0BCFF"})
For a list of all customizable colors, see the Theme Color Reference:
Sharp frame
You can change the corner style.
# Default is "rounded".
stylesheet = qdarktheme.setup_theme(corner_shape="sharp")
QPalette and stylesheet
You can also only load QPalette and stylesheet. qdarktheme.setup_theme uses the following functions internally.
palette = qdarktheme.load_palette(theme="dark")
stylesheet = qdarktheme.load_stylesheet(theme="dark")
Example
To check all Qt widgets, run:
python -m qdarktheme.widget_gallery

Other files are covered by PyQtDarkTheme's MIT license. The accent detector(qdarktheme/_os_appearance/_accent/_mac_detect) is inspired by darkdetect(3-clause BSD License).
