addTreeModelListener

public void addTreeModelListener(javax.swing.event.TreeModelListener l)

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

Specified by:

addTreeModelListener in interface javax.swing.tree.TreeModel

Parameters:

l - the listener to add

getChild

public java.lang.Object getChild(java.lang.Object parent,
                                 int index)

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)).

Specified by:

getChild in interface javax.swing.tree.TreeModel

Parameters:

parent - a node in the tree, obtained from this data source

Returns:

the child of parent at index index

getChildCount

public int getChildCount(java.lang.Object parent)

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.

Specified by:

getChildCount in interface javax.swing.tree.TreeModel

Parameters:

parent - a node in the tree, obtained from this data source

Returns:

the number of children of the node parent

getIndexOfChild

public int getIndexOfChild(java.lang.Object parent,
                           java.lang.Object child)

Returns the index of child in parent. If parent is null or child is null, returns -1.

Specified by:

getIndexOfChild in interface javax.swing.tree.TreeModel

Parameters:

parent - a note in the tree, obtained from this data source

child - the node we are interested in

Returns:

the index of the child in the parent, or -1 if either child or parent are null

getRoot

public java.lang.Object getRoot()

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

Specified by:

getRoot in interface javax.swing.tree.TreeModel

Returns:

the root of the tree

isLeaf

public boolean isLeaf(java.lang.Object node)

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.

Specified by:

isLeaf in interface javax.swing.tree.TreeModel

Parameters:

node - a node in the tree, obtained from this data source

Returns:

true if node is a leaf

removeTreeModelListener

public void removeTreeModelListener(javax.swing.event.TreeModelListener l)

Removes a listener previously added with addTreeModelListener.

Specified by:

removeTreeModelListener in interface javax.swing.tree.TreeModel

Parameters:

l - the listener to remove

See Also:

addTreeModelListener(javax.swing.event.TreeModelListener)

valueForPathChanged

public void valueForPathChanged(javax.swing.tree.TreePath path,
                                java.lang.Object newValue)

Messaged when the user has altered the value for the item identified by path to newValue. If newValue signifies a truly new value the model should post a treeNodesChanged event.

Specified by:

valueForPathChanged in interface javax.swing.tree.TreeModel

Parameters:

path - path to the node that the user has altered

newValue - the new value from the TreeCellEditor

fireTreeStructureChanged

protected void fireTreeStructureChanged(RootWrapper (src)  oldRoot)
