QDarkStylesheet

Build Status Docs Status Latest PyPI version License: MIT License: CC BY 4.0 Conduct

The most complete dark stylesheet for Qt application (Qt4, Qt5, PySide, PySide2, PyQt4, PyQt5, QtPy, PyQtGraph, Qt.Py).

Installation

Python

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

C++

  • Download/clone the project and copy the following files to your application directory (keep the existing directory hierarchy):

    • qdarkstyle/style.qss
    • qdarkstyle/style.qrc
    • qdarkstyle/rc/ (the whole directory)
  • Add qdarkstyle/style.qrc to your .pro file as follows:

    RESOURCES += qdarkstyle/style.qrc
  • Load the stylesheet:

    QFile f(":qdarkstyle/style.qss");
    
    if (!f.exists())   {
        printf("Unable to set stylesheet, file not found\n");
    }
    else   {
        f.open(QFile::ReadOnly | QFile::Text);
        QTextStream ts(&f);
        qApp->setStyleSheet(ts.readAll());
    }

Note: The ":" in the file name is necessary to define that file as a resource library. For more information see the discussion here.

Usage

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 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_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 *example folder. You can run the script without installing qdarkstyle. You only need to have PySide or PySide2 or PyQt4 or PyQt5 installed on your system.*

What is new?

In the version 2.6 and later, a reestructure 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.

From 2.7, we have added SCSS, so the palette can be accessed programatically. Also many scripts were added to give freedom fro developers who wants to change the colors of our palette. All images and icons were revised, also creating SVG files for all of them.

From 2.8, we moved to QtPy to simplify your code, thus this is a required dependency now.
