Class KeyPopulator<UJO extends Ujo,T>

java.lang.Object
  org.ujorm.wicket.component.grid.KeyPopulator<UJO,T>

Type Parameters:

UJO -

All Implemented Interfaces:

Serializable, org.apache.wicket.extensions.markup.html.repeater.data.grid.ICellPopulator<UJO>, org.apache.wicket.extensions.markup.html.repeater.data.table.IColumn<UJO,Key<UJO,T>>, org.apache.wicket.model.IDetachable, org.apache.wicket.util.io.IClusterable

public class KeyPopulator<UJO extends Ujo,T>
extends Object
implements org.apache.wicket.extensions.markup.html.repeater.data.grid.ICellPopulator<UJO>, org.apache.wicket.extensions.markup.html.repeater.data.table.IColumn<UJO,Key<UJO,T>>

A convenience implementation of ICellPopulator that adds a label that will display the value of the specified key. Non-string properties will be converted to a string before display.

Example:

 List<ICellPopulator> columns = KeyPopulator.list
         ( Employee.ID
         , Employee.FIRSTNAME
         , Employee.LASTNAME
         , Employee.EMAIL
         );
 
 final WebMarkupContainer table = new WebMarkupContainer("table");
 final DataGridView grid = new DataGridView("gridPanel", columns, new InnerPeopleProvicer());
 table.setOutputMarkupId(true);
 grid.setItemsPerPage(20);
 add(table);
 table.add(grid);
 add(new AjaxPagingNavigator("tableNavigator", grid));
