Examples of org.itsnat.comp.tree.ItsNatTreeCellUI

org.itsnat.comp.tree.ItsNatTreeCellUI
Contains visual information of a tree node.
This interface is the "componentized" version of {@link org.itsnat.core.domutil.ElementTreeNode} andfollows a similar philosophy. The objective is similar to {@link org.itsnat.comp.list.ItsNatListCellUI}applied to tree nodes. Child index, row, tree path, deep level etc are tolerant to tree changes (are automatically updated).
