Java Inventor is a new application builder and IDE for Java and JavaFX. The IDE is a currently a JavaFX/Swing hybrid, but applications built in Javi using the automatic forms builder or the integrated UI builder can run either under Swing or JavaFX.
The parts of Java Inventor that are currently implemented in JavaFX can be viewed in the video link below and include the WelcomePanel, the Project ToolBar, the Project HomePage, the Forms generator page, the Reports generator page, the BookMarks editor page and the Publish Page.
All of the UI in Java Inventor is implemented using the Javi.UI classes, which allow development in either JavaFX or Swing, with trivial switching between them. Eventually all of Java Inventor will be switched to run as JavaFX.
