Direct Known Subclasses:

CheckedFolder, CheckFolder

public class Folder<T>
extends StyledLinkLabel<T>

A typical folder representation of nodes in a tree. The link is used to expand/collapse the tree depending on the AbstractTree.State of the current node. Nodes without children are not clickable. Subclasses may change this behavior by overriding isClickable() and onClick(Optional)
