The AboutBox is an elegant way to inform your end users about your Vaadin application and acknowledge the contributions of its developers. Typically installed in the main window, it presents a compact box at the top of the window that can be expanded to provide more details. Additionally, a click listener for a link can be added to provide even more information, gather feedback, or direct users to another website. Try out different configurations in the demo! Note: The implementation is based on CSS3 and may not currently work in every browser. Tested with FF3.6, Chrome 12, and Safari 5.
