addTreeModelListenerback to summary
public void addTreeModelListener(TreeModelListener treeModelListener)

Implements javax.swing.tree.TreeModel.addTreeModelListener.

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

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

Parameters
treeModelListener:TreeModelListener

the listener to add

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)).

Parameters
parent:Object

a node in the tree, obtained from this data source

index:int

index of child to be returned

Returns:Object

the child of parent at index index

Annotations
@Override
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.

Parameters
parent:Object

a node in the tree, obtained from this data source

Returns:int

the number of children of the node parent

Annotations
@Override
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.

Parameters
parent:Object

a node in the tree, obtained from this data source

child:Object

the node we are interested in

Returns:int

the index of the child in the parent, or -1 if either child or parent are null or don't belong to this tree model

Annotations
@Override
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.

Returns:Object

the root of the tree

Annotations
@Override
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.

Parameters
node:Object

a node in the tree, obtained from this data source

Returns:boolean

true if node is a leaf

@Override
removeTreeModelListenerback to summary
public void removeTreeModelListener(TreeModelListener treeModelListener)

Implements javax.swing.tree.TreeModel.removeTreeModelListener.

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

Removes a listener previously added with addTreeModelListener.

Parameters
treeModelListener:TreeModelListener

the listener to remove

Annotations
@Override
valueForPathChangedback to summary
public void valueForPathChanged(TreePath treePath, Object o)

Implements javax.swing.tree.TreeModel.valueForPathChanged.

Doc from javax.swing.tree.TreeModel.valueForPathChanged.

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.

Parameters
treePath:TreePath

path to the node that the user has altered

o:Object

the new value from the TreeCellEditor
