Called DockFX and found on GitHub, the library was built to fill what the developer cites as a void for docking frameworks available for JavaFX. "DockFX is a library that enables application developers to create customizable and fluid interfaces for their end users, move side panels, hide panels out of view, or drag panels out and get a closer look," developer Robert Colton, a computer science student at Penn State University said in an email. "The library makes it possible to create an interface similar to Visual Studio, Eclipse, or GIMP in very little time without much work. Because the library is targeted at a wide variety of developers, it can also result in a more stable control with more features as it is maintained and improved by a larger number of users."
Open source and still in an early stage of development, DockFX supports CSS and styling. It will add support for FXML, which is an XML-based declarative markup language for JavaFX, and DockBar, supporting floating toolbars. "The library saves the developer from having to write the boilerplate code that makes such a customizable user interface possible by providing a common and reusable control," said Colton.
Plans call for possibly including DockFX with Oracle's ControlsFX project to provide high-quality UI controls for JavaFX. "I believe that this is the most appropriate course to take because my goal was to build a common control that accommodates all Java users, including proprietary application developers," Colton said.
JavaFX was unveiled by Sun Microsystems in May 2007. "I feel that the focus on JavaFX as an RIA platform has detracted from providing a comparable feature set to Swing's traditional desktop-oriented approach, potentially leaving it to be suitable for neither," Colton said. "I also believe that more attention should be focused on JavaFX for Linux and MacOS where the platform under-performs Windows. Despite my concerns, I feel that the JavaFX developers have been doing an outstanding job and I commend them for the work that they've done in building this new platform."
