Method Detail

treeNodesChanged

public void treeNodesChanged(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.

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

treeNodesInserted

public void treeNodesInserted(TreeModelEvent e)

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

treeNodesRemoved

public void treeNodesRemoved(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.

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

treeStructureChanged

public void treeStructureChanged(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.

Use e.getPath() to get the path to the node. e.getChildIndices() returns null.

Parameters:
e
