Details
Constructor

Node(argv)

Methods:

add(n) 

#
  Add the given {Node} to this {Node}'s list of subnodes.
  @param  The {Node} to add.

expand() 

#
  Expand all the {Nodes} below this node.

generate_all_postorder() 

#
  Generate all the {Nodes} in this subtree, including this {Node},
  in postorder ordering.

generate_all_preorder() 

#
  Generate all the {Nodes} in this subtree, including this {Node},
  in preorder ordering.

generate_open_postorder() 

#
  Generate all open {Nodes} in this subtree, including this {Node},
  in postorder ordering.

generate_open_preorder() 

#
  Generate all the open {Nodes} in this subtree, including this {Node},
  in preorder ordering.

node_delete(n) 

#
  Delete the given {Node} from the subnodes.

node_delete2(x, n)

set_always_expandable() 

#
  This configures the {Node} so that it is always treated as though it has subnodes
  for display purposes, event though it may in fact have no subnodes.

set_bmps(x) 

#
  Set the bitmaps for this node.  The parameter should provide a list of 3
  bitmaps.  The first is displayed if the {Node} is open and has subnodes, the
  second is displayed if the {Node} is closed and has subnodes, and the third is
  displayed if the node has no subnodes.
  @param x  A list of 3 bitmaps.

set_label(x) 

#
  Set the label for this node.

toggle_opened() 

#
