FLib

FLib is a software library comprising high-quality Java components that are both free and open source. Currently, it has wizard and calendar components alongside a table layout manager. The wizard component simplifies the process of creating multi-step user dialogs while the calendar component can operate independently or as part of a combo-box drop-down.

The table layout seamlessly replaces GridBagLayout and makes it remarkably easier to use. Moreover, while the components are in English, full localization is possible. The calendar component is mostly internationalized as it is and automatically adjusts to the locale, making the software multilingual-friendly.
