Flamingo 5.0 Released
The Flamingo project aims to provide a Swing implementation of the Office 2007 ribbon container and related components. The Flamingo component suite follows the core Swing guidelines in the external APIs and the internal implementation details.
In an effort to address the limitations of the core Swing button components, version 5.0 adds right-to-left support for command buttons, command menu buttons, and command popup menus. There is also new support for rich tooltips.
