⚠ The image quality may be lower on Qt5(PyQt5, PySide2) due to the use of svg. You can add the following attribute to improve the quality of images.

app.setAttribute(Qt.ApplicationAttribute.AA_UseHighDpiPixmaps)

Light theme

app.setStyleSheet(qdarktheme.load_stylesheet("light"))

Dark and Light palette

You can get color of dark and light theme by loading QPalette. To load palette, run:

palette = qdarktheme.load_palette()
# or
palette = qdarktheme.load_palette("light")

For example, you can apply a link color to your application.

import sys

from PyQt5.QtGui import QPalette
from PyQt5.QtWidgets import QApplication

import qdarktheme

app = QApplication(sys.argv)
dark_palette = qdarktheme.load_palette()
palette = app.palette()
palette.setColor(QPalette.ColorRole.Link, dark_palette.link().color())
app.setPalette(palette)
