org.apache.wicket.extensions.markup.html.repeater.data.table.PropertyColumn<T,S>

Type Parameters:

T - The Model object type

S - the type of the sort property

All Implemented Interfaces:

FilteredPropertyColumn

public class PropertyColumn<T,S>
extends AbstractColumn<T,S>
implements IExportableColumn<T,S>

A convenience implementation of column that adds a label to the cell whose model is determined by the provided wicket property expression (same as used by PropertyModel) that is evaluated against the current row's model object

Example

 columns[0] = new PropertyColumn(new Model<String>("First Name"), "name.first");
 

The above will attach a label to the cell with a property model for the expression "name.first"
