# superqt — Missing widgets and components for PyQt/PySide

License: permissive · Maintenance: active · Downloads: 385.6K/mo

## What it is and what it does

superqt extends PyQt and PySide with a collection of community-built widgets and utilities that fill gaps in the standard Qt library. It provides specialized UI components like multi-handle range sliders and enhanced comboboxes, alongside practical tools for threading in Qt applications and icon generation from font files (supporting Material Design Icons and Font Awesome). The package is designed to work across macOS, Windows, and Linux with modern Python versions (3.10 and above) and multiple Qt bindings.

Developers use superqt when they need UI elements beyond what the native QtWidgets module offers, or when they want ready-made solutions for common Qt patterns like font-based icons and thread management. It's actively maintained and tested against multiple Qt versions, making it suitable for projects that need reliable, cross-platform custom widgets without building them from scratch.

Use it for:

- Build a data-range selector UI with a multi-handle slider instead of separate min/max inputs.
- Generate application icons dynamically from Material Design Icons or Font Awesome font files.
- Implement thread-safe Qt operations using superqt's threading decorators and utilities.
- Extend a PyQt/PySide application with specialized combobox variants not in the standard library.
- Create cross-platform desktop tools that need consistent custom widgets on macOS, Windows, and Linux.

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

Provides additional Qt widgets and UI components (like range sliders and custom comboboxes) not included in the standard PyQt/PySide libraries, plus utilities for threading and icon generation from font files.

Yes. superqt is actively maintained, has low install friction, carries a permissive BSD license, and fills a genuine gap in PyQt/PySide by providing well-tested custom widgets and utilities. No known vulnerabilities. Install it if you need range sliders, font-based icons, or threading helpers in a Qt application.

## Install

pip install superqt
uv add superqt
poetry add superqt

## Installing superqt

Before you install: Low install friction with only three runtime dependencies (pygments, qtpy, typing-extensions). Actively maintained with recent commits and a stable release cadence; last update was 88 days ago.

License in practice: BSD 3-Clause License (permissive) allows commercial and private use with minimal restrictions—include a copy of the license and retain copyright notices.

Quickstart:

pip install superqt

from superqt.widgets import QRangeSlider
slider = QRangeSlider()

Requires Python 3.10 or above and either PyQt5 (5.11+), PyQt6, or PySide6 to be installed separately.

Verify before relying:

- Whether all documented widgets are production-ready or if some remain experimental despite Beta status.
- Performance characteristics when rendering many custom widgets in a single application.
- Compatibility matrix details for specific PyQt5/PyQt6/PySide6 version combinations.
