Resolution: Fixed

> Issue Type: New Feature
> Components: wtk
> Affects Versions: 1.4
> Reporter: Greg Brown
> Assignee: Greg Brown
> Fix For: 1.4.1
>
>
> Currently, it is difficult to bind complex data types to data-driven
> components such as ListView, ListButton, and Spinner. For example, a
> ListButton may be used to present the user with a set of options, each of
> which has a numeric ID and a text description. The list button displays the
> text content, but the value is actually identified by the ID property. It
> would be ideal to bind only the ID to the list button, but currently it is
> only possible to bind an entire item.
> This could be solved by providing a mapping interface that translates between
> bound values and list items:
> public interface BindMapping {
> public int indexOf(List<?> listData, Object item);
> public Object get(List<?> listData, int index);
> }
> Implementations of this interface would perform the translation between the
> bound value and the contents of the list.
