SIP is a tool to create Python bindings for C and C++ libraries. It was originally developed to create PyQt, the Python bindings for the Qt toolkit, but can be used to create bindings for any C or C++ library.

SIP comprises a code generator and a Python module. The code generator processes a set of specification files and generates C or C++ code, which is then compiled to create the bindings extension module. The SIP Python module provides support functions to the automatically generated code.

Grantlee Templates can be used for theming and generation of other text such as code. The syntax uses the syntax of the Django template system, and the core design of Django is reused in Grantlee.

Qlementine Icons is a modern, vector, elegant, free, and open-source icon library designed for use with a C++ library that enhances the appearance of your QtWidgets application.

The Qt Speech module enables a Qt application to support accessibility features such as text-to-speech, which is useful for end-users who are visually challenged or cannot access the application for whatever reason. The most common use case where text-to-speech comes in handy is when the end-user is driving and cannot attend the incoming messages on the phone. In such a scenario, the messaging application can read out the incoming message.

WebSocket is a web-based protocol designed to enable two-way communication between a client application and a remote host. The Qt WebSockets module provides C++ and QML interfaces that enable Qt applications to act as a server that can process WebSocket requests, or a client that can consume data received from the server, or both.

QtImGui allows the ImGui C++ GUI library to be used by Qt applications within subclasses of QOpenGLWidget and QOpenGLWindow.

Qt Quick 3D Physics provides a high-level API for physics simulation. It supports simulating interactive rigid bodies as well as static meshes and non-colliding bodies used for detecting overlaps. Every simulated body can have its own physical properties like mass, density and friction.

The Qt Graphs module enables you to visualize data in 2D and 3D graphs.

QScintilla is a port to Qt of Neil Hodgson's Scintilla C++ editor control. QScintilla includes features especially useful when editing and debugging source code. These include support for syntax styling, error indicators, code completion and call tips.

This package provides the Python bindings.

The Qt Gamepad module is an add-on library that enables Qt applications to support the use of gamepad hardware and in some cases remote control equipment. The module provides both QML and C++ interfaces. The primary target audience are embedded devices with fullscreen user interfaces, and mobile applications targeting TV-like form factors.

Pyotherside is a Qt plugin providing access to a Python 3 interpreter from QML for creating asynchronous mobile and desktop UIs with Python.

Accounts SSO is a framework for application developers who wish to acquire, use and store web account details and credentials. It handles the authentication process of an account and securely stores the credentials and service-specific settings.
