Not tested on linux.
Installation Method

Last released version
pip install qtvscodestyle

Latest development version
pip install git+https://github.com/5yutan5/QtVSCodeStyle

Usage
Use default theme
To apply VS Code's default theme, run:
import sys

from PySide6.QtWidgets import QApplication, QMainWindow, QPushButton

import qtvscodestyle as qtvsc

app = QApplication(sys.argv)
main_win = QMainWindow()
push_button = QPushButton("QtVSCodeStyle!!")
main_win.setCentralWidget(push_button)

stylesheet = qtvsc.load_stylesheet(qtvsc.Theme.DARK_VS)
# stylesheet = load_stylesheet(qtvsc.Theme.LIGHT_VS)
app.setStyleSheet(stylesheet)

main_win.show()

app.exec()

⚠ 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)

Available Themes
To check available themes, run:
qtvsc.list_themes()

Theme name Symbol
___________ ______

Light (Visual Studio): LIGHT_VS
Quiet Light : QUIET_LIGHT
Solarized Light : SOLARIZED_LIGHT
Abyss : ABYSS
Dark (Visual Studio) : DARK_VS
Kimbie Dark : KIMBIE_DARK
Monokai : MONOKAI
Monokai Dimmed : MONOKAI_DIMMED
Red : RED
Solarized Dark : SOLARIZED_DARK
Tomorrow Night Blue : TOMORROW_NIGHT_BLUE
Dark High Contrast : DARK_HIGH_CONTRAST

Use extension themes
If you want to use a third party theme, you will need to download the theme file from the repository and load theme by using load_stylesheet().
Simple example using One Dark Pro.
One Dark Pro is one of the most used themes for VS Code.

First of all, download or copy and paste the theme file from the repository.
Then load the stylesheet using the saved file.
theme_file = r"OneDark-Pro.json"
stylesheet = qtvsc.load_stylesheet(theme_file)
app.setStyleSheet(stylesheet)

Color customization
The configuration method is the same as workbench.colorCustomizations of VSCode.
About color code format, see https://code.visualstudio.com/api/references/theme-color#color-formats.
# Set the button text color to red.
custom_colors = {"button.foreground": "#ff0000"}
stylesheet = qtvsc.load_stylesheet(qtvsc.Theme.DARK_VS, custom_colors)

To check available color id, run:
qtvsc.list_color_id()

Color ids is almost the same as VS Code's theme color document. Some own color ids like disabled attribute are available.
SVG and Font QIcon for VS Code style
You can also use various icon fonts and svg as QIcon.

QtVSCodeStyle identifies icons by symbolic and icon name.
The following symbolic are currently available to use:

Font Awesome Free(5.15.4) - Font Icon

FaRegular: Regular style
FaSolid : Solid style
FaBrands: Brands style

vscode-codicons

Vsc: VS Code style - SVG Icon

You can use icon browser that displays all the available icons.
python -m qtvscodestyle.examples.icon_browser

Two functions, theme_icon() and icon() are available.
theme_icon() create QIcon will automatically switch the color based on the set color-id when you call load_stylesheet(Another Theme).
star_icon = qtvsc.theme_icon(qtvsc.Vsc.STAR_FULL, "icon.foreground")
button = QToolButton()
button.setIcon(star_icon)

# star_icon switch to the MONOKAI's "icon.foreground" color.
qtvsc.load_stylesheet(qtvsc.Theme.MONOKAI)

icon() create QIcon with static color.
# Set red
star_icon = qtvsc.icon(qtvsc.Vsc.STAR_FULL, "#FF0000")
button = QToolButton()
button.setIcon(star_icon)

# Keep red.
qtvsc.load_stylesheet(qtvsc.Theme.MONOKAI)

Create new theme
You can create your own theme. The configuration method is the same as theme extension of VS Code.
The only properties to set are the theme type and colors.
Dictionary, json file(json with comment), and string formats are supported.

Dictionary
custom_theme = {
"type": "dark", # dark or light or hc(high contrast)
"colors": {
"button.background": "#1e1e1e",
"foreground": "#d4d4d4",
"selection.background": "#404040",
},
}
stylesheet = qtvsc.load_stylesheet(custom_theme)

String(Json with comment text)
custom_theme = """
{
"type": "dark",
"colors": {
"button.background": "#1e1e1e",
"foreground": "#d4d4d4",
"selection.background": "#404040"
}
}
"""
# You need to use loads_stylesheet
stylesheet = qtvsc.loads_stylesheet(custom_theme)

Json with comment
custom_theme_path = r"custom_theme.json"
# or you can use pathlib.Path object
# custom_theme_path = pathlib.Path("custom_theme.json")
stylesheet = qtvsc.load_stylesheet(custom_theme_path)

If you customize using json files, you can use json schema.
Copy json schema from qvscodestyle/validate_colors.json
Using schema example for VS Code: https://code.visualstudio.com/docs/languages/json#_json-schemas-and-settings
Check common widgets
To check common widgets, run:
python -m qtvscodestyle.examples.widget_gallery

Custom properties
This module provides several custom properties for applying VS Code's style.
For example, if you set the activitybar to type custom property of QToolbar, the style of the activitybar will be applied.
activitybar = QToolBar()
activitybar.setProperty("type", "activitybar")

Widget

Command for demo

QToolBar

activitybar
python -m qtvscodestyle.examples.activitybar

QPushButton

python -m qtvscodestyle.examples.pushbutton

QLineEdit

warning, error
python -m qtvscodestyle.examples.lineedit

QFrame
type
h_line, v_line
python -m qtvscodestyle.examples.line

Build resources
QtVSCodeStyle creates and deletes icon files dynamically using temporary folder.
The style sheet you created will no longer be available after you exit the program.
Therefore, QtVSCodeStyle provides the tool to build style sheets with resources that can be used after you exit the program.
In order to build style sheets, run:
python -m qtvscodestyle.resource_builder --theme dark_vs

It is also possible to apply custom colors.
python -m qtvscodestyle.resource_builder -t dark_vs --custom-colors-path custom.json

// custom.json
{
"focusBorder": "#ff0000",
"foreground": "#ff00ff"
}

In order check details of the command, run:
python -m qtvscodestyle.resource_builder --help

⚠ Resource files and svg folders should always be in the same directory.

⚠ Not support on PyQt6. PyQt6 removed Qt’s resource system.

How to use in Qt Designer

Run the qtvscodestyle.resource_builder command and generate resources.
Copy the stylesheet text from stylesheet.qss.
Paste the copied stylesheet into stylesheet property of the top-level widget.
Register the resource.qrc in generated folder to the resource browser. If you use Qt Creator, add resource.qrc and svg folder to your project.
