Interface ListitemRenderer<T>

All Known Implementing Classes:

BindListitemRenderer

public interface ListitemRenderer<T>

Identifies components that can be used as "rubber stamps" to paint the cells in a Listbox.

If you need better control, your renderer can also implement ListitemRendererExt. If you need better control for generting Listgroup and Listgroupfoot, your renderer can also implement ListgroupRendererExt.

In addition, you could also implement RendererCtrl. For example, starts an transaction, and uses it to render all items for the same request.
