@Deprecated
public abstract class DefaultAbstractTree
extends AbstractTree

Tree class that contains convenient functions related to presentation of the tree, which includes junction link, tree item selection link, spacers (with lines) and default tree item and folder icons.

The class itself adds no component to tree items. If you use this class directly, you have to implement populateTreeItem() on your own. If you want to use an existing (complete) tree class, use Tree

This class allows you to choose between 3 types of links. setLinkType(LinkType)

public LinkType getLinkType()

Deprecated.

Returns the current type of links on tree items.

Returns:

The link type

setLinkType

public void setLinkType(LinkType linkType)

Deprecated.

Sets the type of links on tree items. After the link type is changed, the whole tree is rebuild and re-rendered.

Parameters:

Creates the indentation element. This element should be placed as first element in the tree item markup to ensure proper indentation of the tree item. This implementation also takes care of lines that connect nodes.

Parameters:

parent - The component parent

id - The component id

node - The tree node for which to create the indentation element

level - The current level

Returns:

The indentation component

Deprecated.

Creates an image placed on junction link. This image actually consists of two spans with different css classes. These classes are specified according to the stylesheet to make the junction image look well together with lines connecting nodes.

Parameters:

parent - The component parent

id - The component id

node - The tree node

Returns:

The component that represents a junction
