SuperQT is a collection of missing widgets and components that extend the capabilities of PyQt and PySide for building rich graphical user interfaces. It provides a variety of useful classes, from advanced sliders and combo boxes to utility functions for array conversion and signal blocking. The current version is 0.8.1, with frequent minor releases to add features and fix bugs, typically on a monthly basis.

Verified usage

Verified import paths — ran on the pinned version, not inferred.

QLabeledSlider

✓ from superqt.sliders import QLabeledSlider

✗ from superqt import QLabeledSlider

Most superqt widgets are in specific submodules, not directly under `superqt`.

QToggleSwitch

✓ from superqt.widgets import QToggleSwitch

✗ from superqt import QToggleSwitch

Widgets like QToggleSwitch are found in the `superqt.widgets` submodule.

QSearchableComboBox

✓ from superqt.combobox import QSearchableComboBox

✗ from superqt import QSearchableComboBox

ComboBoxes are located in the `superqt.combobox` submodule.

qt_signals_blocked

✓ from superqt.utils import qt_signals_blocked

This example demonstrates a basic `QLabeledSlider` from `superqt`, which provides a slider with an integrated label showing its current value. It requires a Qt application context.

import sys from superqt.sliders import QLabeledSlider from PyQt6.QtWidgets import QApplication, QWidget, QVBoxLayout if __name__ == '__main__': app = QApplication(sys.argv) w = QWidget() layout = QVBoxLayout() slider = QLabeledSlider() slider.setRange(0, 100) slider.setValue(50) layout.addWidget(slider) w.setLayout(layout) w.setWindowTitle("SuperQT Labeled Slider Example") w.show() sys.exit(app.exec())

Debug

Known issues

breakingSuperQT v0.8.0 dropped support for Python 3.9 and PySide2. Users on these versions must upgrade their Python environment or switch to a different Qt binding like PyQt5, PyQt6, or PySide6.

fix

Upgrade Python to 3.10+ and install a compatible Qt backend (e.g., `pip install PyQt6`).

affects: >=0.8.0

gotchaSuperQT does NOT install a Qt binding for you. You must explicitly install one (e.g., PyQt6, PySide6, PyQt5) for superqt to function.

fix

Install a Qt backend package alongside superqt: `pip install superqt PyQt6` (or PySide6/PyQt5).

affects: all

gotchaMany superqt components are organized into specific submodules (e.g., `superqt.sliders`, `superqt.widgets`, `superqt.combobox`). Importing directly from `superqt` will often result in an `AttributeError`.

fix

Always check the documentation or examples for the correct submodule path for the specific widget or utility you intend to use. For example, `from superqt.sliders import QLabeledSlider`.
