Thanks to Jeanette for the use of this code found at: https://jdnc-incubator.dev.java.net/source/browse/jdnc-incubator/src/kleopatra/java/org/jdesktop/swingx/renderer/UIPropertiesViewer.java?rev=1.2&view=markup Some ui-icons misbehave in that they unconditionally class-cast to the component type they are mostly painted on. Consequently they blow up if we are trying to paint them anywhere else (f.i. in a renderer). This Icon is an adaption of a cool trick by Darryl Burke found at http://tips4java.wordpress.com/2008/12/18/icon-table-cell-renderer The base idea is to instantiate a component of the type expected by the icon, let it paint into the graphics of a bufferedImage and create an ImageIcon from it. In subsequent calls the ImageIcon is used.
