You should be able to do something like the following:

   public class MyFrame ... {

     ListCellRenderer renderer =
        new MyListCellRenderer();
     ...
   }

Where MyListCellRenderer is declared and defined
in a separate class file.

Or, you may use an anonymous class, as in

   private  ListCellRenderer renderer =
     new DefaultListCellRenderer() {
       public Component getListCellRendererComponent(
         JList list,
         Object value,
         int index,
         boolean isSelected,
         boolean cellHasFocus) {

         return ...;
       }
     };

Then, when you flip to the Designer, "renderer"
should show up in the drop-down list.  At least
that's what I've done in the past and it worked.
You also have to declare "renderer" of type
"ListCellRenderer", not "MyListCellRenderer"
or "DefaultListCellRenderer".

The Designer does not like it if you define
the new renderer class as a nested public
class, or as a class in the same file as
the Frame/Panel class.
