The most complete dark/light style sheet for Qt applications (Qt4*, Qt5, PySide*, PySide2, PySide6, PyQt4*, PyQt5, PyQt6, QtPy, PyQtGraph, Qt.Py) for Python 2*/3 and C++.
Check out the complete documentation.
In the current version 3, qdarkstyle is now working as a theme framework, currently for dark/light themes, keeping styled widgets identical throughout theme colors.
The palette has been redefined and improved (UI/UX) to accept more colors and to be able to implement new themes thanks to the Spyder team collaboration.
The current stable version is using Python 3 (preferable 3.6+) and Qt5 (PyQt5 and PySide 2). Also in this version, an option for Qt6 (PyQt6, PySide6) was added.
The current version for use with Qt6 may still present instabilities.
[*] Python 2, as well as Qt4 (PyQt4 and PySide), will not be supported anymore. They are still there as it is, but no back compatibility, fixes, nor features will be implemented.
We moved to QtPy to simplify your code in v2.8, thus this is a required dependency now. We included special patches in three main categories: operating system, Qt/binding version, application.
Included in that, lots of widgets' styles were included/fixed. A Qt application example (Python only) with almost all types of widgets and combinations were included to serve as a portfolio and a checklist for new styles.
We have added SCSS in v2.7, so the palette can be accessed programmatically. Also, many scripts were added to give freedom to developers who want to change the colors of our palette. All images and icons were revised, also creating SVG files for all of them.
In version 2.6 and later, a restructure stylesheet is provided. The palette has only 9 colors. Most widgets are revised and their styles were improved. We also provide a command line (script) to get info that could be used when opening issues. See the image below.
First stable release of QDarkStyle.
From PyPI: Get the latest stable version of qdarkstyle package using pip (preferable):
pip install qdarkstyle
From code: Download/clone the project, go to qdarkstyle folder then:
You can use the setup script and pip install.
pip install .Or, you can use the setup script with Python:
python setup.py install
Download/clone the project and copy the following files to your application directory (keep the existing directory hierarchy). Substitute the all the THEME words by the currently available (dark/light) the theme you need to use.
- qdarkstyle/THEME/THEMEstyle.qss
- qdarkstyle/THEME/THEMEstyle.qrc
- qdarkstyle/THEME/rc/ (the whole directory)
Add qdarkstyle/THEME/THEMEstyle.qrc to your .pro file as follows:
Load the stylesheet:
Note: The ":" in the file name is necessary to define that file as a resource library. For more information see the discussion here.
If your project already uses QtPy or you need to set it programmatically, it is far more simple
import sys
import qdarkstyle
import os
# set the environment variable to use a specific wrapper
# it can be set to pyqt, pyqt5, pyside or pyside2 (not implemented yet)
# you do not need to use QtPy to set this variable
os.environ['QT_API'] = 'pyqt5'
# import from QtPy instead of doing it directly
# note that QtPy always uses PyQt5 API
from qtpy import QtWidgets
# create the application and the main window
app = QtWidgets.QApplication(sys.argv)
window = QtWidgets.QMainWindow()
# setup stylesheet
# the default system in qdarkstyle uses qtpy environment variable
app.setStyleSheet(qdarkstyle.load_stylesheet())
# run
window.show()
app.exec_()If you are using PyQt5 directly, see the complete example
import sys
import qdarkstyle
from PyQt5 import QtWidgets
# create the application and the main window
app = QtWidgets.QApplication(sys.argv)
window = QtWidgets.QMainWindow()
# setup stylesheet
app.setStyleSheet(qdarkstyle.load_stylesheet_pyqt5())
# or in new API
app.setStyleSheet(qdarkstyle.load_stylesheet(qt_api='pyqt5'))
# run
window.show()
app.exec_()Here is an example using PySide2
import sys
import qdarkstyle
from PySide2 import QtWidgets
# create the application and the main window
app = QtWidgets.QApplication(sys.argv)
window = QtWidgets.QMainWindow()
# setup stylesheet
app.setStyleSheet(qdarkstyle.load_stylesheet_pyside2())
# or in new API
app.setStyleSheet(qdarkstyle.load_stylesheet(qt_api='pyside2'))
# run
window.show()
app.exec_()If you use PyQtGraph, then the code is
import sys
import qdarkstyle
import os
# set the environment variable to use a specific wrapper
# it can be set to PyQt, PyQt5, PySide or PySide2 (not implemented yet)
os.environ['PYQTGRAPH_QT_LIB'] = 'PyQt5'
# import from pyqtgraph instead of doing it directly
# note that PyQtGraph always uses PyQt4 API
from pyqtgraph.Qt import QtGui
# create the application and the main window
app = QtGui.QApplication(sys.argv)
window = QtGui.QMainWindow()
# setup stylesheet
app.setStyleSheet(qdarkstyle.load_stylesheet(qt_api=os.environ['PYQTGRAPH_QT_LIB'])
# run
window.show()
app.exec_()If you are using Qt.py, which is different from qtpy, you should install qtpy then set both to the same binding.
There is an example included in the package. You only need to have PySide2 or PyQt5 is installed on your system.
