The JXStatusBar component is part of the SwingX (https://swingx.dev.java.net) project. As known from many other applications a statusbar provides status informations to users and is generally placed at the bottom of a frame.

SyntheticaAddons provides the Statusbar-UI for every available Synthetica Look and Feel. The UI configuration can be made via UI-defaults and is part of the synth.xml file which belongs to every Synthetica Look and Feel V2.0 or above.
