OpenJFX is made up of three essential elements: source code for the runtime itself, sample applications, and tests. The runtime is further divided up into eight major functional components or modules: Base, Graphics, Controls, Swing, SWT, FXML, Web, and Media. All source code for OpenJFX is contained in a single Mercurial repository named "rt" (which stands for "runtime". It may be simply renamed "openjfx" when we create the repository for the post-Java 8 releases). Within this repository all of the apps, tests, and source code can be found and built. All of these components, or modules, can be found within the rt directory under "modules".
Base
The Base component contains no external dependencies, and does not rely on any graphics APIs. It is possible to use the Base component in any application, including pure headless components. It is comprised of APis including FX beans and Observable collections.
