Constructor Detail

AutomatedTreeModel

public AutomatedTreeModel(AutomatedTreeNode root)

Creates an AutomatedTreeModel in which any node can have children.

Parameters:

root - an AutomatedTreeNode object that is the root of the tree

See Also:

AutomatedTreeModel(AutomatedTreeNode, boolean)

AutomatedTreeModel

public AutomatedTreeModel(AutomatedTreeNode root,
                          boolean asksAllowsChildren)

Creates an AutomatedTreeModel specifying whether any node can have children, or whether only certain nodes can have children.

Parameters:

root - an AutomatedTreeNode object that is the root of the tree

asksAllowsChildren - a boolean, false if any node can have children, true if each node is asked to see if it can have children

See Also:

DefaultTreeModel.asksAllowsChildren

Method Detail

setRoot

public void setRoot(javax.swing.tree.TreeNode root)

Sets the root to root. A null root implies the tree is to display nothing, and is legal.

treeNodesChanged

public void treeNodesChanged(javax.swing.event.TreeModelEvent e)

Invoked after a node (or a set of siblings) has changed in some way. The node(s) have not changed locations in the tree or altered their children arrays, but other attributes have changed and may affect presentation. Example: the name of a file has changed, but it is in the same location in the file system.

Specified by:

treeNodesChanged in interface javax.swing.event.TreeModelListener

treeNodesInserted

public void treeNodesInserted(javax.swing.event.TreeModelEvent e)

Invoked after nodes have been inserted into the tree.

Specified by:

treeNodesInserted in interface javax.swing.event.TreeModelListener

treeNodesRemoved

public void treeNodesRemoved(javax.swing.event.TreeModelEvent e)

Invoked after nodes have been removed from the tree. Note that if a subtree is removed from the tree, this method may only be invoked once for the root of the removed subtree, not once for each individual set of siblings removed.

Specified by:

treeNodesRemoved in interface javax.swing.event.TreeModelListener

treeStructureChanged

public void treeStructureChanged(javax.swing.event.TreeModelEvent e)

Invoked after the tree has drastically changed structure from a given node down. If the path returned by e.getPath() is of length one and the first element does not identify the current root node the first element should become the new root of the tree.

Specified by:

treeStructureChanged in interface javax.swing.event.TreeModelListener
