org.jdesktop.swingx.renderer.DefaultListRenderer
public class DefaultListRenderer
Adapter to glue SwingX renderer support to core api. It has convenience constructors to create a LabelProvider, optionally configured with a StringValue and horizontal alignment. Typically, client code does not interact with this class except at instantiation time.
Note: core DefaultListCellRenderer shows either an icon or the element's toString representation, depending on whether or not the given value is of type icon or implementors. This renderer's empty/null provider constructor takes care of configuring the default provider with a converter which mimics that behaviour. When instantiating this renderer with any of the constructors which have converters as parameters, it's up to the client code to supply the appropriate converter, if needed:
StringValue sv = new StringValue() {
public String getString(Object value) {
if (value instanceof Icon) {
return "";
}
return StringValue.TO_STRING.getString(value);
}
};
StringValue lv = new MappedValue(sv, IconValue.ICON);
listRenderer = new DefaultListRenderer(lv, alignment);

Note: the default provider is configured with a custom StringValue which behaves exactly as core DefaultListCellRenderer: depending on whether or not given value is of type icon or implementors, it shows either the icon or the element's toString.
