Package docking.widgets.tree

Class AbstractGTreeRootNode

java.lang.Object

docking.widgets.tree.AbstractGTreeNode

docking.widgets.tree.AbstractGTreeRootNode

All Implemented Interfaces:

GTreeNode, GTreeRootNode, java.lang.Comparable<GTreeNode>, java.lang.Iterable<GTreeNode>

Direct Known Subclasses:

InProgressGTreeRootNode, NoProjectNode

public abstract class AbstractGTreeRootNode
extends AbstractGTreeNode
implements GTreeRootNode

Simple base class for GTRootNodes. If your root node has different internal logic than other nodes, then extend this class. If you root node has the same internal logic as other nodes, then it is probably better to extend your other node class and implement the getGTree() and setGTree() methods yourself.
