Language Bindings: Difference between revisions
(Qlarifying to newcomers to Qt that QML is not an alternative to C++, for Qt developers. To become a Qt full-stack developer, ones needs to learn C++ or e.g. Python.) |

Programming Language Support & Language Bindings
The Qt API is implemented in C++, and provides additional features for easier cross-platform development. QML – introduced with Qt Quick and JavaScript-like declarative, language designed to describe the user interface of a program: both what it looks like, and how it behaves. As an alternative to using C++, Qt offers other languages, including Python . Officially, Python bindings are being maintained by the project, under the name of Qt for Python.
C++ Development with Qt
Qt provides an intuitive C++ class library with a rich set of application build blocks for C++ development. Qt goes beyond C++ in the areas of inter-object communication and flexibility for advanced GUI development. Qt adds the following features to C++:
- Powerful mechanism for inter-object communication called signals and slots
- Queryable and designable object properties
- Powerful events and events filters
- Contextual string translation for internationalization
- Sophisticated interval driven timers that make it possible to elegantly integrate many tasks in an event-driven GUI
- Hierarchical and queryable object trees that organize object ownership in a natural way
- Guarded pointers that are automatically set to 0 when the referenced object is destroyed, unlike normal C++ pointers which become dangling pointers when their objects are destroyed
- A dynamic cast works across library boundaries.
QML Development with Qt Quick
QML is a declarative, JavaScript-based language designed to describe the user interface of a program: both what it looks like, and how it behaves. In QML, a user interface is specified as a tree of objects with properties, like in JSON.
- JavaScript, HTML and CSS skills can be used to code complete front-end apps
- Optimized for touch-based, animated mobile UIs
- Includes a set of graphical and behavioral building blocks: QML Types
- No C++ knowledge required for UI creation, while it can be extended with C++
Qt for Python
The Qt for Python project provides the PySide6 (and PySide2) module allowing users to develop Qt and QML application easily from Python.
- You can find more information for the project, which is currently available as a Technical Preview, in the wiki page.
- Compatible with Qt 5.11+. Currently in Qt6, Qt for Python is released on a similar cycle as the Qt framework, and supports Python 3.8+ (in Qt 6.6.0)
Qt for Python (PySide6) is the official set of Python wheels that The Qt Company provides.

This project aims to create Mono/.NET libraries that wrap Qt thus enabling its usage through C#. It relies on the excellent CppSharp.
Qt for C#/Mono/.Net (Qml.Net)
Qml.Net is cross-platform integration of Qml/QtQuick for .NET Core/.NET Framework/Mono. It is a binding that brings .NET types into JavaScript with full interoperability.
Qt for D (QtE5)
QtE5 is a binding of the Qt framework to the D programming language version 2.
Qt for Haskell (qtHaskell)
The qtHaskell project provides a comprehensive set of Haskell bindings for 50 Qt modules with extensive examples and demo programs including qtHaskell versions of Tetrix, DiagramScene, PathDeform and the Qt Asteroids game which uses FRP (Functional Reactive Programming) techniques to control game states and behaviors.
Qtah
The qtah project provides a set of Haskell bindings for Qt.
Qt for Julia (QML.jl)
This project provides bindings to Julia.
Qt Quick for Haskell (HsQML)
HsQML provides a Haskell binding to the Qt Quick framework. It allows you to write graphical applications where the front-end is written in Qt Quick's QML language (incorporating JavaScript) and the back-end is written in Haskell.
Qt Quick for OCaml (lablqml)
QML Bindings to OCaml.
Node.js and Qt Widgets (NodeGui)
Build performant, native and cross-platform desktop applications with Node.js and CSS like styling. NodeGUI is powered by Qt Widgets which makes it CPU and memory efficient as compared to other chromium based solutions like electron.
Qt Quick for Node.js (Brig)
Qt Quick: The Brig project provides library for Qt Quick framework, making it possible to write graphical applications in JavaScript and QML languages.
QML bindings for Nelson language
Nelson is an array programming language providing a powerful open computing environment for engineering and scientific applications using modern C/C++ libraries and others state of art numerical libraries.
The QML engine enables nelson programs to display and manipulate graphical content using Qt's QML framework. see some examples: https://www.youtube.com/watch?time_continue=1&v=L3fsg4zhTjE
