superqt
Missing widgets and components for PyQt/PySide
Decision gist · record as of 2026-08-14
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.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.10 or above and either PyQt5 (5.11+), PyQt6, or PySide6 to be installed separately.
- 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.

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.

More User Interfaces packages
Wraps any iterable to display a real-time progress bar in the terminal or Jupyter notebook, showing iteration count, elapsed time, and estimated time remaining.
Formats and parses numbers, file sizes, timespans, and other values into human-readable text; provides terminal interaction utilities including ANSI text styling and user prompts.
Adds colored output to Python's standard logging module using ANSI escape sequences, with automatic fallback support for Windows terminals.
However, it is abandoned and receives no maintenance, so it will not adapt to future Python changes or platform updates.
Formats argparse and optparse help output with rich styling, colors, and markup to improve CLI readability with minimal code changes.
progressbar2 renders text-based progress bars in the terminal, handling custom widgets, concurrent bars, unknown-length progress, and clean output around logs and prints.
InquirerPy provides interactive command-line prompts (text input, confirmations, selections, checkboxes, fuzzy search) for building conversational CLI interfaces in Python.
However, the project is dormant (last release 2022-06-27), so adopt it only if you need its specific feature set (especially the fuzzy prompt) and can tolerate no…
