class
BasicTreeUI.TreeModelHandler
extends Object
implements TreeModelListener
Forwards all TreeModel events to the TreeState.
public TreeModelHandler()
Constructor
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. To indicate the root has changed, childIndices and
children will be null. Use e.getPath() to get the parent of the changed
node(s). e.getChildIndices() returns the index(es) of the changed
node(s).
Parameters: e is the event that occured
Invoked after nodes have been inserted into the tree. Use e.getPath() to
get the parent of the new node(s). e.getChildIndices() returns the
index(es) of the new node(s) in ascending order.
Parameters: e is the event that occured
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. Use e.getPath() to get the former parent of the deleted
node(s). e.getChildIndices() returns, in ascending order, the index(es)
the node(s) had before being deleted.
Parameters: e is the event that occured
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. Use e.getPath() to get the path
to the node. e.getChildIndices() returns null.
Parameters: e is the event that occured
