public Object getRoot()
TreeModel
getRoot in interface TreeModel
public Object getChild(Object parent,
int index)
TreeModelparent at index index
in the parent's child array.
getChild in interface TreeModelparent - a node in the tree
parent at index indexpublic int getChildCount(Object parent)
TreeModelparent.
getChildCount in interface TreeModelparent - a node in the tree
parentpublic boolean isLeaf(Object node)
TreeModeltrue if node is a leaf.
isLeaf in interface TreeModelnode - a node in the tree
node is a leaf
public void valueForPathChanged(TreePath path,
Object newValue)
TreeModelpath has changed to newValue.
If newValue signifies a truly new value
the model should post a treeNodesChanged event.
