  pip install git+https://github.com/5yutan5/PyQtDarkTheme.git@main
  

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:

• Usage Guide

# 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.

qdarktheme.setup_theme("light")

qdarktheme.setup_theme("auto")

On macOS, qdarktheme also syncs with accent 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:

• Theme Color

You can change the corner style.

# Default is "rounded".
stylesheet = qdarktheme.setup_theme(corner_shape="sharp")

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")

To check all Qt widgets, run:

python -m qdarktheme.widget_gallery

The svg files for the PyQtDarkTheme are derived Material design icons(Apache License Version 2.0). Qt stylesheets are originally fork of QDarkStyleSheet(MIT License). 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).
