SwingJavaFX

SwingJavaFX is a project that aims to bridge the gap between JavaFX and Swing, two graphical user interface toolkits for Java. It allows developers to embed JavaFX components within existing Swing applications or to use Swing components within JavaFX applications. This provides a way to gradually migrate older Swing applications to the more modern JavaFX platform or to leverage the strengths of both toolkits in a single application.

The primary functionality of SwingJavaFX is achieved through a set of utility classes that facilitate interoperability. These classes handle the complexities of rendering JavaFX content in a Swing context and vice versa. For instance, one can create a JavaFX scene graph and then render it onto a Swing `JPanel` using specialized components provided by the SwingJavaFX library. Conversely, Swing components can be wrapped and integrated into a JavaFX scene.

This approach offers several advantages. Developers can incrementally update their Swing applications without a complete rewrite. They can introduce modern JavaFX features like CSS styling, rich media playback, and more advanced graphics capabilities into their existing user interfaces. It also allows for the reuse of existing Swing components and libraries within new JavaFX projects. The project is typically used by developers who have legacy Swing applications and want to modernize them or who need to combine the functionalities of both toolkits for specific use cases.
