<!-- Document : package Created on : Oct 11, 2007, 10:38:26 AM Author : Shai Almog--><!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"><html> <head> <title></title> </head> <body> <p> Lists are highly customizable and serve as the basis for {@link com.sun.lwuit.ComboBox} and other components (such as carousels etc) they employ a similar MVC approach to Swing including the renderer pattern. {@link com.sun.lwuit.list.ListCellRenderer} allows us to customize the appearance of a list entry, it works as a "rubber stamp" by drawing the rendered component and discarding its state thus allowing very large lists with very little component state overhead. </p> <p> {@link com.sun.lwuit.list.ListModel} allows us to represent the underlying data structure for the {@link com.sun.lwuit.List}/{@link com.sun.lwuit.ComboBox} without requiring all the data to reside in memory or in a specific structure. This allows a model to represent a data source of any type, coupled with the renderer the data source can be returned in an internal representation state and still be rendered properly to the screen. </p> </body></html>
