Design Java Swing-based user interfaces with Appleis Interface Builder.
nib4j 1.0 is a simple but powerfull Java library that permits the use of Appleis Interface Builder to design Swing-based user interfaces. It creates Swing menus, frames and dialogs from Carbon nib files and provides a complete separation of UI and application code. nib4j supports both absolute and relative positioning/sizing, internationalization and more than 25 UI controls, including real floating palette windows and Mac OS X 10.3 group boxes.
By using the included "nib4j Viewer" you can try out your UI without writing any code and generate the necessary Java source to access the Swing components.
