The JXHeader component is part of the SwingX (https://swingx.dev.java.net) project. SyntheticaAddons provides an UI-delegate ( HeaderUI) for the Synthetica Look and Feel.

A JXHeader is a special area which is helpful to provide additional informations - especially in conjunction with JFrames/JDialogs. A JXHeader contains a title panel, a description panel and an image panel to display an optional header image.
