FLib is a Development::Components & Libraries software developed by Antonio Freixas. After our trial and test, the software was found to be official, secure and free. Here is the official description for FLib: FLib is a free, open source library of high-quality Java components. It currently contains wizard and calendar components and a table layout manager. The wizard component makes it easy to create multi-step user dialogs. The calendar component can be used by itself or as part of a combo-box drop-down. The table layout replaces GridBagLayout and is much easier to use.
While the components are in English, complete localization is possible. The calendar component is mostly internationalized as is and automatically adapts to the locale. you can download FLib 1.1.1 free now.
