org.itsnat.comp.ui .ItsNatTreeUI

All known Subclasses:   org.itsnat.impl.comp.ui .ItsNatTreeUIImpl,
ItsNatTreeUI
public interface ItsNatTreeUI extends ItsNatElementComponentUI(Code)
Is the base interface of the User Interface of a tree component.
Tree nodes are managed using the current tree structure and renderer.

Current implementation uses the tree data model when necessary and relays heavily on org.itsnat.core.domutil.ElementTree and related interfaces/objects.

If the tree is rootless there is no markup to the root, method calls like getParentElementFromRow(0) returns null.

Current implementation does not use the data model
