QRainbowStyleSheet

The most complete customizable stylesheet for Qt application (PySide2, PyQt5, QtPy, Qt.Py).

Preview

From version v0.8 qrainbowstyle.windows module supports native Windows calls. Features:

• Borders snapping
• Minimize, restore, close animations
• Size grips on borders
• Frame shadow
• Aero shake

On Linux and Darwin qrainbowstyle will load class with its own implementation of these features. Due to a bug in Qt, window minimizing is not supported on MacOS.

Frameless windows

Installation

From PyPI: Get the latest stable version of qrainbowstyle package using pip (preferable):

pip install qrainbowstyle

From code: Download/clone the project, go to qrainbowstyle 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

Usage

Frameless windows

import os
import sys
import qrainbowstyle
import qrainbowstyle.windows

from qtpy.QtWidgets import QApplication
from qtpy.QtCore import Qt

QApplication.setAttribute(Qt.AA_UseHighDpiPixmaps)
QApplication.setAttribute(Qt.AA_EnableHighDpiScaling)

app = QApplication(sys.argv)
app.setStyleSheet(qrainbowstyle.load_stylesheet(style="oceanic"))

# Package options
# qrainbowstyle.alignButtonsLeft()
# qrainbowstyle.userDarwinButtons()
qrainbowstyle.setAppName("My new application")
qrainbowstyle.setAppIcon("/path/to/icon.ico")

# Create frameless mainwindow
win = qrainbowstyle.windows.FramelessWindow()

# Example of using signals
win.closeClicked.connect(lambda: print("Close clicked!"))

# Create content widget and pass reference to main window
widget = SomeWidget(win)

# Add widget to main window and show it
win.addContentWidget(widget)
win.show()

sys.exit(app.exec())

Style sheet

import os
import sys
import qrainbowstyle

# set the environment variable to use a specific wrapper
# it can be set to pyqt, pyqt5, or pyside2
# 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 qrainbowstyle uses qtpy environment variable
app.setStyleSheet(qrainbowstyle.load_stylesheet())

# run
window.show()
app.exec_()

If you are using PyQt5 directly, see the complete example

import sys
import qrainbowstyle
from PyQt5.QtWidgets import QApplication, QMainWindow

# create the application and the main window
app = QApplication(sys.argv)
window = QMainWindow()

# setup stylesheet
app.setStyleSheet(qrainbowstyle.load_stylesheet_pyqt5())
# or in new API
app.setStyleSheet(qrainbowstyle.load_stylesheet(qt_api='pyqt5'))

# run
window.show()
app.exec_()

Here is an example using PySide2

import sys
import qrainbowstyle
from Pyside2.QtWidgets import QApplication, QMainWindow

# create the application and the main window
app = QApplication(sys.argv)
window = QMainWindow()

# setup stylesheet
app.setStyleSheet(qrainbowstyle.load_stylesheet_pyside2())
# or in new API
app.setStyleSheet(qrainbowstyle.load_stylesheet(qt_api='pyside2'))

# 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.

Available styles

Currently available styles are:

• Oceanic
• QDarkStyle3
• QDarkstyle3Light
• LightOrange
• DarkOrange
• QDarkStyle (original)

Select style by using style= keyword argument

qrainbowstyle.load_stylesheet(style="lightorange")

Widgets

In v0.6 I added a few new widgets which automatically load colors from current stylesheet's palette.

GoogleMapsView

GoogleMapsView allows to load Google Maps to application. Supports creating markers and polylines. Call handler captures all map/markers/polylines actions such as map move or marker click/double click.

StylePicker

StylePicker is small widget used to change stylesheet without restarting application. Only styles generated by QRainbowStyle are supported. Widget is available in 3 versions: horizontal, vertical and grid.

QRoundProgressBar

Modified version of https://github.com/ozmartian/QRoundProgressBar. I replaced PyQt5 imports with qtpy and fixed widget background.

QtWaitingSpinner

Modified version of https://github.com/fbjorn/QtWaitingSpinner. Added fade out and fade in. Spinner designer can be found in qrainbowstyle/widgets/QtWaitingSpinner/designer.py

Building your own style sheet

Download/clone the project, go to qrainbowstyle folder then:

1. Create new style in palette.py by subclassing BasePalette. New palette should have unique name, for example DeepBluePalette

2. Override default colors by your own. Example:

   class DeepBluePalette(BasePalette):
       COLOR_BACKGROUND_1 = "#263238"
       COLOR_BACKGROUND_2 = "#2f4048"
       COLOR_BACKGROUND_3 = "#34474f"
       COLOR_BACKGROUND_4 = "#394d57"
       COLOR_BACKGROUND_5 = "#3d545f"
       COLOR_BACKGROUND_6 = "#425b67"
   
       COLOR_TEXT_1 = Gray.B130
       COLOR_TEXT_2 = Gray.B110
       COLOR_TEXT_3 = Gray.B90
       COLOR_TEXT_4 = Gray.B80
   
       COLOR_ACCENT_1 = "#0a4542"
       COLOR_ACCENT_2 = "#136460"
       COLOR_ACCENT_3 = "#097D74"
       COLOR_ACCENT_4 = "#56BFBA"
       COLOR_ACCENT_5 = "#C4D6DB"
   
       TITLE_BAR_BACKGROUND_COLOR = COLOR_ACCENT_3
       TITLE_BAR_BUTTONS_HOVER_COLOR = COLOR_ACCENT_4
       TITLE_BAR_BUTTONS_DISABLED_COLOR = COLOR_ACCENT_1
       TITLE_BAR_TEXT_COLOR = COLOR_TEXT_1
   
       OPACITY_TOOLTIP = 230

3. Generate resources for your style by running scripts/process_qrc.py

4. Install package by running:

   pip install .

5. To use style sheet in your application:

   import qrainbowstyle
   
   app = QApplication(sys.argv)
   app.setStyleSheet(qrainbowstyle.load_stylesheet(style="deepblue")

What is new?

Starting with new package name, I added frameless widnows and possibility to design your own stylesheet. I added few new SVG icons such as title bar icons.

• 0.6 - widget subpackage
• 0.8 - Windows API support
• 0.9 - modern style for frameless windows, full support for new color system
