The parent node of this node, or null if this
is the root node. | | protected boolean | selected
| | protected String | target
The window target for the hyperlink identified by the
action property, if this node is selected
by the user. | | protected TreeControl | tree
The TreeControl instance representing the
entire tree. | | protected int | width
The display width necessary to display this item (if it is visible). |
| action | | protected String action(Code) | | The hyperlink to which control will be directed if this node
is selected by the user.

| children | | protected ArrayList children(Code) | | The set of child TreeControlNodes for this node, in the
order that they should be displayed.
|
| expanded | | protected boolean expanded(Code) | | Is this node currently expanded?
