public Class SimpleTreeModel

extends Object
implements TreeModel
Class Inheritance
All Implemented Interfaces
javax.swing.tree.TreeModel
Known Direct Subclasses
sun.jvm.hotspot.ui.treetable.SimpleTreeTableModel
Imports
java.util.*, javax.swing.*, javax.swing.event.*, javax.swing.tree.*
A very simple tree model which allows the root to be set, so we can reuse the same model for various types of data; the specialization is contained within the nodes. This tree model operates on SimpleTreeNodes.

Method Detail

addTreeModelListenerback to summary
public void addTreeModelListener(TreeModelListener l)

Implements javax.swing.tree.TreeModel.addTreeModelListener.

Doc from javax.swing.tree.TreeModel.addTreeModelListener.

Adds a listener for the TreeModelEvent posted after the tree changes.

fireTreeStructureChangedback to summary
public void fireTreeStructureChanged()
getChildback to summary
public Object getChild(Object parent, int index)

Implements javax.swing.tree.TreeModel.getChild.

Doc from javax.swing.tree.TreeModel.getChild.

Returns the child of parent at index index in the parent's child array. parent must be a node previously obtained from this data source. This should not return null if index is a valid index for parent (that is index >= 0 && index < getChildCount(parent)).

getChildCountback to summary
public int getChildCount(Object parent)

Implements javax.swing.tree.TreeModel.getChildCount.

Doc from javax.swing.tree.TreeModel.getChildCount.

Returns the number of children of parent. Returns 0 if the node is a leaf or if it has no children. parent must be a node previously obtained from this data source.

getIndexOfChildback to summary
public int getIndexOfChild(Object parent, Object child)

Implements javax.swing.tree.TreeModel.getIndexOfChild.

Doc from javax.swing.tree.TreeModel.getIndexOfChild.

Returns the index of child in parent. If either parent or child is null, returns -1. If either parent or child don't belong to this tree model, returns -1.

getRootback to summary
public Object getRoot()

Implements javax.swing.tree.TreeModel.getRoot.

Doc from javax.swing.tree.TreeModel.getRoot.

Returns the root of the tree. Returns null only if the tree has no nodes.

isLeafback to summary
public boolean isLeaf(Object node)

Implements javax.swing.tree.TreeModel.isLeaf.

Doc from javax.swing.tree.TreeModel.isLeaf.

Returns true if node is a leaf. It is possible for this method to return false even if node has no children. A directory in a filesystem, for example, may contain no files; the node representing the directory is not a leaf, but it also has no children.

removeTreeModelListenerback to summary
public void removeTreeModelListener(TreeModelListener l)

Implements javax.swing.tree.TreeModel.removeTreeModelListener.

Doc from javax.swing.tree.TreeModel.removeTreeModelListener.

Removes a listener previously added with addTreeModelListener.

public void valueForPathChanged(TreePath path, Object newValue)
