Constructor Detail

EditablePropertyColumn

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

EditablePropertyColumn

public EditablePropertyColumn(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

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

EditablePropertyColumn

public EditablePropertyColumn(org.apache.wicket.model.IModel<String> headerModel,
                      String propertyExpression,
                      S sortProperty)

Constructor. The column id is omitted in this constructor, because the property expression is used as column id.

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

EditablePropertyColumn

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

Constructor. The column id is omitted in this constructor, because the property expression is used as column id.

Parameters:

headerModel - model for column header

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

Method Detail

isLightWeight

public boolean isLightWeight(org.apache.wicket.model.IModel<I> rowModel)

Returns whether this column is uses a component for cell in given row (not lightweight) or an IRenderable implementation. Generally, if the cell is non-interactive (label only), it's better to use an IRenderable implementation, as it has zero memory footprint

Specified by:

isLightWeight in interface IGridColumn<M,I,S>

Overrides:

isLightWeight in class AbstractLightWeightColumn<M,I,S>

Parameters:

rowModel - model for given row

Returns:

true if the cell is lightweight, false otherwise

getFieldModel

protected org.apache.wicket.model.IModel<P> getFieldModel(org.apache.wicket.model.IModel<I> rowModel)

newCellPanel

protected EditableCellPanel<M,I,P,S> newCellPanel(String componentId,
                                      org.apache.wicket.model.IModel<I> rowModel,
                                      org.apache.wicket.model.IModel<P> cellModel)

newCell

public org.apache.wicket.Component newCell(org.apache.wicket.markup.html.WebMarkupContainer parent,
                                  String componentId,
                                  org.apache.wicket.model.IModel<I> rowModel)

Creates a new cell component. This method is called for rows that are not lightweight ( IGridColumn.isLightWeight(IModel) returns false ).

Specified by:

newCell in interface IGridColumn<M,I,S>

Overrides:

newCell in class AbstractLightWeightColumn<M,I,S>

Parameters:

parent - Parent component. This is passed in only for convenience, the method implementation is not supposed to add the newly created component to the parent.

componentId - required id of newly created components

rowModel - model for given row

Returns:

new cell component

addValidators

protected void addValidators(org.apache.wicket.markup.html.form.FormComponent<P> component)

getCellCssClass

public String getCellCssClass(org.apache.wicket.model.IModel<I> rowModel,
                     int rowNum)

Returns the cell specified by rowModel. The class is applied to the appropriate <td> element in the grid.

Specified by:

getCellCssClass in interface IGridColumn<M,I,S>

Overrides:

getCellCssClass in class AbstractColumn<M,I,S>

Parameters:

rowModel - model for given row

rowNum - index of row for DataGrid, -1 for TreeGrid

Returns:

cell style class or null

cellClicked

public boolean cellClicked(org.apache.wicket.model.IModel<I> rowModel)

Description copied from class: AbstractColumn

Allows to override default behavior when a row is clicked. Depending on grid settings the default behavior can select the item. If this method returns true the default behavior will be suppressed.

Specified by:

cellClicked in interface IGridColumn<M,I,S>

Overrides:

cellClicked in class AbstractColumn<M,I,S>

Parameters:

rowModel - Model for clicked row

Returns:

true if the default behavior when row is clicked should be supressed, false otherwise.

isClickToEdit

protected boolean isClickToEdit()
