              S sortProperty)

Constructor.

Parameters:

columnId - column identified (must be unique within the grid)

headerModel - model for column header

propertyExpression - property expression used to get the displayed value for row object

sortProperty - optional string that will be returned by ISortState to indicate that the column is being sorted

PropertyColumn

public PropertyColumn(String columnId,
              org.apache.wicket.model.IModel<String> headerModel,
              String propertyExpression)

Constructor.

Parameters:

columnId - column identified (must be unique within the grid)

headerModel - model for column header

Parameters:

headerModel - model for column header

propertyExpression - property expression used to get the displayed value for row object

sortProperty - optional string that will be returned by ISortState to indicate that the column is being sorted

Parameters:

headerModel - model for column header

propertyExpression - property expression used to get the displayed value for row object
