The Qt framework contains a comprehensive set of highly intuitive and modularized C++ library classes and is loaded with APIs to simplify your application development. Qt produces highly readable, easily maintainable and reusable code with high runtime performance and small footprint – and it's cross-platform.
These special-purpose modules may only be available on some development platform. Many add-on modules are either feature-complete and exist for backward compatibility or are only applicable to certain platforms.Browse all Qt Add-Ons
OpenGL support classes. Deprecated in favor of the QOpenGL classes in the Qt GUI module.
Provides a framework to develop a Wayland compositor.
Provides access to sensor hardware and motion gesture recognition.
Displays web content in a QML application by using APIs native to the platform, without the need to include a full web browser stack.

The Qt Group prioritizes addressing potential vulnerability threats and security concerns in its products. With its broad cross-platform applicability and extensive API, the Qt framework is susceptible to cyber risks on diverse fronts. Furthermore, Qt is developed as a open source project, requiring vulnerability report analysis by designated staff members and external contributors. Since its inception, the Qt Group actively participates in the relevant steering groups and takes prompt action upon vulnerability reports. Vulnerability reports are governed by specific procedures outlined in the Qt Project Security Policy.
