# QtJambi - UI Framework for Java

## Overview

QtJambi is a UI framework for Java and Kotlin based upon [Qt](https://www.qt.io).

It makes the entire Qt framework available by providing Java wrappers for all C++ types and functions in the Qt API.

Like Qt framework, QtJambi is modular and provides different libraries for various application fields.

The basic module `qtjambi` provides bindings for native modules `QtCore`, `QtGui` and `QtWidgets` which are a good starting point to create sophisticated user interfaces.

The modules `qtjambi-qml`and `qtjambi-quick` allow you to devine user interfaces in QML language based upon `QtQuick`.

Further modules deal with concurrency, SQL and XML processing, statemachines, OpenGL, web content and multimedia integration, printsupport, visualization, connectivity, special hardware and many more.

## Availability

[![Maven Central](https://maven-badges.herokuapp.com/maven-central/io.qtjambi/qtjambi/badge.svg)](https://search.maven.org/artifact/io.qtjambi/qtjambi)

[![Release (latest by date)](https://img.shields.io/github/v/release/OmixVisualization/qtjambi)](https://github.com/OmixVisualization/qtjambi/releases)

QtJambi is available for Java 8 or 11 and higher using Qt5.15 and Qt6 in Java on Windows, Android Linux and macOS. 

Most Qt modules are available as QtJambi module as [listed here](https://www.qtjambi.io/doc/Modules.md). All modules are published as Maven Artifact.

By default, the native components of only essential modules are made available on Maven. Please make a request via **[Issues](../../issues)** if you require native components not yet available.

## Support

QtJambi is an open source project making the power of Qt available for your Java projects free of charge. However, this project is causing ongoing costs. 

Please consider supporting this project by donation. Your support is highly appreciated.

## History

QtJambi for Qt4 and has been originally developed by Trolltech, the predecessor of The Qt Company. 

The successive open source project provides bindings of Qt5 and Qt6 releases for latest Java JDK versions.

The original idea for QtJambi was and still is to generated the the Java bindings by inspection of the C++ header files of the Qt implementation.

The necessary JNI (Java Native Interface) code and `.java` files are automatically generated. The QtJambi kernel cares for object lifecycle and native memory management.
