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

The Qt Tools module provides a set of applications to browse the documentation, translate applications, generate help files and other stuff that helps in Qt development.

PyQt is a set of Python v2 and v3 bindings for the Qt application framework. The bindings are implemented as a set of Python modules and contain over 620 classes.

The Qt SCXML module provides functionality to create state machines from SCXML files. This includes both dynamically creating state machines (loading the SCXML file and instantiating states and transitions) and generating a C++ file that has a class implementing the state machine. It also contains functionality to support data models and executable content.

The Qt Serial Bus API provides classes and functions to access the various industrial serial buses and protocols, such as CAN, ModBus, and others.

This plugin for the Accounts-SSO SignOn daemon handles the OAuth 1.0 and 2.0 authentication protocols.

This package contains the union of PyQt and the Qscintilla extension.

The Qt Charts module provides a set of easy to use chart components. It uses the Qt Graphics View Framework, therefore charts can be easily integrated to modern user interfaces. Qt Charts can be used as QWidgets, QGraphicsWidget, or QML types. Users can easily create impressive graphs by selecting one of the charts themes.

The Qt QML module provides a framework for developing applications and libraries with the QML language. It defines and implements the language and engine infrastructure, and provides an API to enable application developers to extend the QML language with custom types and integrate QML code with JavaScript and C++.

The Qt WebEngine module provides support for web applications using the Chromium browser project. The Chromium source code has Google services and binaries removed, and adds modular support for using system libraries.

KD SingleApplication is a helper class for single-instance policy applications.

The Qt Graphical Effects module provides a set of QML types for adding visually impressive and configurable effects to user interfaces. Effects are visual items that can be added to Qt Quick user interface as UI components. The API consists of over 20 effects provided as separate QML types. The effects cover functional areas such as blending, masking, blurring, coloring, and many more.

The Qt Location module provides an interface for location, positioning and geolocation plugins.

The Qt Data Visualization module provides a way to visualize data in 3D as bar, scatter, and surface graphs. It is especially useful for visualizing depth maps and large quantities of rapidly changing data, such as data received from multiple sensors. The look and feel of graphs can be customized by using themes or by adding custom items and labels to them.

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.

Qt6CT is a program that allows users to configure Qt6 settings (such as icons, themes, and fonts) in desktop environments or window managers, that don't provide Qt integration by themselves.

The Qt5WebEngine module provides support for web applications using the Chromium browser project. The Chromium source code has Google services and binaries removed, and adds modular support for using system libraries.

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.

KD SOAP is a tool for creating client applications for web services using the XML based SOAP protocol and without the need for a dedicated web server.

DOtherSide is a C language library for creating bindings for the QT QML language. The following features are implementable from a binding language:

• Creating custom QObject

• Creating custom QAbstractListModels

• Creating custom properties, signals and slots

• Creating from QML QObject defined in the binded language

• Creating from Singleton QML QObject defined in the binded language

The Qt Purchasing module provides and in-app API for purchasing goods and services.

SIP is used to write self contained extension modules, i.e. without a library to be wrapped. This SIP extension module provides support for the PyQt6 package.

libQGLViewer is a C++ library based on Qt that eases the creation of OpenGL 3D viewers.

It provides some of the typical 3D viewer functionalities, such as the possibility to move the camera using the mouse, which lacks in most of the other APIs. Other features include mouse manipulated frames, interpolated keyFrames, object selection, stereo display, screenshot saving and much more. It can be used by OpenGL beginners as well as to create complex applications, being fully customizable and easy to extend.

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.
