public class xt_DocumentTreePanel
extends JPanel
implements TreeModelListener, DocumentListener

xt_DocumentTreePanel is a JPanel containing a JTree which has knowledge of the xm_DocumentModel which it displays, and which can be notified of document change events relating to it.

##

xt_DocumentTreePanel(xm_DocumentModel)
  Constructor.

##

changedUpdate(DocumentEvent)
  Gives notification that an attribute or set of attributes changed.
getTree()
  Get the document tree.
getTreeScrollPane()
  Get the tree scroll pane.
insertUpdate(DocumentEvent)
  Gives notification that there was an insert into the document.
removeTreeModelListener()
  Stop listening to tree model changes.
removeUpdate(DocumentEvent)
  Gives notification that a portion of the document has been removed.
treeNodesChanged(TreeModelEvent)

  Invoked after a node (or a set of siblings) has changed in some way.

treeNodesInserted(TreeModelEvent)

  Invoked after nodes have been inserted into the tree.

  e.path() returns the parent of the new nodes

  e.childIndices() returns the indices of the new nodes in ascending order.

treeNodesRemoved(TreeModelEvent)

  Invoked after nodes have been removed from the tree.

treeStructureChanged(TreeModelEvent)

  Invoked after the tree has drastically changed structure from a given node down.

##

xt_DocumentTreePanel

     public xt_DocumentTreePanel(xm_DocumentModel InputDocumentModel)

  Constructor.

##

removeTreeModelListener

     public void removeTreeModelListener()

  Stop listening to tree model changes.

getTreeScrollPane

     public JScrollPane getTreeScrollPane()

  Get the tree scroll pane.

  Returns:
    The tree scroll pane

getTree

     public JTree getTree()

  Get the document tree.

treeNodesChanged

     public void treeNodesChanged(TreeModelEvent InputTreeModelEvent)

  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.

  e.path() returns the path the parent of the changed node(s).

  e.childIndices() returns the index(es) of the changed node(s).

treeNodesInserted

     public void treeNodesInserted(TreeModelEvent InputTreeModelEvent)

  Invoked after nodes have been inserted into the tree.

  e.path() returns the parent of the new nodes

  e.childIndices() returns the indices of the new nodes in ascending order.

treeNodesRemoved

     public void treeNodesRemoved(TreeModelEvent InputTreeModelEvent)

  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.

  e.path() returns the former parent of the deleted nodes.

  e.childIndices() returns the indices the nodes had before they were deleted in ascending order.

treeStructureChanged

     public void treeStructureChanged(TreeModelEvent InputTreeModelEvent)

  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.

  e.path() holds the path to the node.

  e.childIndices() returns null.

insertUpdate

     public void insertUpdate(DocumentEvent InputDocumentEvent)

  Gives notification that there was an insert into the document. The given range bounds the freshly inserted region.

  Parameters:
    InputDocumentEvent - - the document event

removeUpdate

     public void removeUpdate(DocumentEvent InputDocumentEvent)

  Gives notification that a portion of the document has been removed. The range is given in terms of what the view last saw (that is, before updating sticky positions).

  Parameters:
    InputDocumentEvent - - the document event

changedUpdate

     public void changedUpdate(DocumentEvent InputDocumentEvent)

  Gives notification that an attribute or set of attributes changed.

  Parameters:
    InputDocumentEvent - - the document event
