Constructor Detail

AbstractTreeColumn

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

Creates instance with specified column id, header model and sort property.

Parameters:

columnId - column identifier - must be unique within the grid

headerModel - model for column title

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

AbstractTreeColumn

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

Creates instance with specified column id and header model

Parameters:

columnId - column identifier - must be unique within the grid

headerModel - model for column title

Method Detail

getIcon

protected Icon getIcon(org.apache.wicket.model.IModel<I> model)

Returns the icon for given TreeNode.

Specified by:

getIcon in class BaseTreeColumn<T extends TreeModel & Serializable,I extends TreeNode & Serializable,S>

Parameters:

model - model used to access the TreeNode

Returns:

icon instance or null if no icon should be displayed

newNodeComponent

protected abstract org.apache.wicket.Component newNodeComponent(String id,
                                           org.apache.wicket.model.IModel<I> model)

Creates the node component.

Specified by:

newNodeComponent in class BaseTreeColumn<T extends TreeModel & Serializable,I extends TreeNode & Serializable,S>

Parameters:

id - component id

model - model used to access the TreeNode

Returns:

newly created component instance

newCell

public final 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<T extends TreeModel & Serializable,I extends TreeNode & Serializable,S>

Overrides:

newCell in class BaseTreeColumn<T extends TreeModel & Serializable,I extends TreeNode & Serializable,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

newCell

public final IRenderable<I> newCell(org.apache.wicket.model.IModel<I> rowModel)

Creates a new IRenderable instance that is used to render to render the output of cell for given row. This method is called for rows that are lightweight ( IGridColumn.isLightWeight(IModel) returns true ).

Specified by:

newCell in interface IGridColumn<T extends TreeModel & Serializable,I extends TreeNode & Serializable,S>

Overrides:

newCell in class AbstractColumn<T extends TreeModel & Serializable,I extends TreeNode & Serializable,S>

Parameters:

rowModel - model for given row

Returns:

IRenderable instance
