Programming Languages
You can develop Qt applications using one or a combination of the following languages:
- C++
- QML
- Python
- JavaScript
QML and C++

Platforms
Develop Qt applications on macOS, Linux, and Windows desktop platforms. Qt is platform-independent, which means you can compile same code base for other target platforms.

Basics
Learn the Qt basics that define the foundation of Qt.
UI
Use the Qt Quick and Qt Widget UI technology. Qt Quick interfaces are fluid, dynamic, and are best on touch interfaces. Qt Widgets are for creating complex desktop applications. You can create Qt Quick and Qt Widgets interfaces with the target platform's native look and feel.
Graphics and Multimedia
Display graphical elements and handle multimedia content. Qt abstracts the target platforms' underlying graphics APIs so that you can focus on writing the application code. Play back audio and video files and render them on screen, as well as record audio and video from the system's cameras and microphones.

Data processing and I/O
Retrieve and store data in different formats.
Networking and Connectivity
Develop applications that communicate with Web services and exchange data (JSON or CBOR) with applications on other devices.
In addition, Qt applications can use remote objects or gRPC and protobuf to communicate with service endpoints.

Web Technologies
Embed content from the World Wide Web into your Qt applications on platforms that do not have a native web engine.
Alternatively, you can create a web channel for peer-to-peer communication between a server and a client.

Tools
Qt installations contain Qt libraries, examples, documentation, and the necessary development tools, such as the Qt Creator integrated development environment (IDE) and Qt Design Studio for developing Qt Quick Applications.
Accessibility
Write accessible software by letting users scale the UI, change font size and color contrast, use the keyboard for navigation, have UI text read aloud with a synthesized voice, and change the UI language.
