Interface IlxWListCellRenderer

All Known Implementing Classes:

IlxWDefaultListCellRenderer

public interface IlxWListCellRenderer

Identifies components that can be used as "rubber stamps" to render the cells in an IlxWList. For example, to use a IlxWLabel as a IlxWListCellRenderer, you would write something like this:

 class MyCellRenderer extends IlxWLabel implements IlxWListCellRenderer {

     public IlxWComponent getListCellRendererComponent(

         IlxWList list,

         Object value,

         int index,

         boolean isSelected)

     {

         setText(value.toString());

         if (isSelected) {

           getStyle().set("backgroundColor", "red");

           getStyle().set("color", "white");

         } else {

           getStyle().set("backgroundColor", "white");

           getStyle().set("color", "black");

         }

         return this;

     }

 }
