Method Detail

createLocalFileSystemFileNode

public static FileSystemTreeModel.FileNode createLocalFileSystemFileNode(FileSystemTreeModel.FileNode parent,
                                                                         java.lang.String sName)

createLocalFileSystemFileNode

public static FileSystemTreeModel.FileNode createLocalFileSystemFileNode(FileSystemTreeModel.FileNode parent)

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

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

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

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.

getIndexOfChild

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

Returns the index of child in parent.

Specified by:

getIndexOfChild in interface javax.swing.tree.TreeModel

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

removeTreeModelListener(javax.swing.event.TreeModelListener)

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)

fireTreeNodesInserted

protected void fireTreeNodesInserted(java.lang.Object source,
                                     java.lang.Object[] path,
                                     int[] childIndices,
                                     java.lang.Object[] children)

fireTreeNodesRemoved

protected void fireTreeNodesRemoved(java.lang.Object source,
                                    java.lang.Object[] path,
                                    int[] childIndices,
                                    java.lang.Object[] children)
