Constructor Detail

TreeTableModelTreeModelAdapter

public TreeTableModelTreeModelAdapter(TreeTableModel<R,T> treeTableModel)
Method Detail

getRoot

public Object getRoot()
Returns the root of the tree. Returns null only if the tree has no nodes.

Specified by:
getRoot in interface TreeModel
Returns:
the root of the tree

getChild

public Object getChild(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 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(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 TreeModel
Parameters:
parent - a node in the tree, obtained from this data source
Returns:
the number of children of the node parent

isLeaf

public boolean isLeaf(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 TreeModel
Parameters:
node - a node in the tree, obtained from this data source
Returns:
true if node is a leaf

valueForPathChanged

public void valueForPathChanged(TreePath path,
                                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 TreeModel
Parameters:
path - path to the node that the user has altered
newValue - the new value from the TreeCellEditor

getIndexOfChild

public int getIndexOfChild(Object parent,
                           Object child)
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.

Specified by:
getIndexOfChild in interface 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 or don't belong to this tree model

addTreeModelListener

public void addTreeModelListener(TreeModelListener l)
Adds a listener for the TreeModelEvent posted after the tree changes.

Specified by:
addTreeModelListener in interface TreeModel
Parameters:
l - the listener to add
See Also:
TreeModel.removeTreeModelListener(javax.swing.event.TreeModelListener)

removeTreeModelListener

public void removeTreeModelListener(TreeModelListener l)
Removes a listener previously added with addTreeModelListener.

Specified by:
removeTreeModelListener in interface TreeModel
Parameters:
l - the listener to remove
See Also:
TreeModel.addTreeModelListener(javax.swing.event.TreeModelListener)
