Class BaseTreeColumn<T extends TreeModel & Serializable,I extends TreeNode & Serializable,S>

java.lang.Object

com.inmethod.grid.column.AbstractColumn<T,I,S>

com.inmethod.grid.treegrid.BaseTreeColumn<T,I,S>

Type Parameters:

T - tree model object type

I - node model object type

All Implemented Interfaces:

IGridColumn<T,I,S>, Serializable, org.apache.wicket.model.IDetachable, org.apache.wicket.util.io.IClusterable

Direct Known Subclasses:

AbstractTreeColumn

public abstract class BaseTreeColumn<T extends TreeModel & Serializable,I extends TreeNode & Serializable,S>
extends AbstractColumn<T,I,S>

INTERNAL

Base class for column containing the actual tree in TreeGrid. Users should not subclass this class directly. Rather than that the AbstractTreeColumn class should be used.

Method Detail

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

Specified by:

newCell in class AbstractColumn<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

newNodeComponent

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

Creates the node component.

Parameters:

id - component id

model - model used to access the TreeNode

Returns:

newly created component instance

getIcon

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

Returns the icon for given TreeNode.

Parameters:

model - model used to access the TreeNode

Returns:

icon instance or null if no icon should be displayed

getTreeGrid

public TreeGrid<T,I,S> getTreeGrid()

Returns the TreeGrid this column belongs to.

Returns:

TreeGrid this column belongs to.

setGrid

public void setGrid(AbstractGrid<T,I,S> grid)

Invoked before the first render of the grid. Column that need grid reference can implement this method and store the reference.

Specified by:

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

Overrides:

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

Parameters:

grid - grid that contains this column
