The Node Parameter
Each node on the tree must be specified by a node parameter. Node parameters can be supplied to the tree applet in one of two ways,
i) Html PARAM tags or
ii) In a text file
Html Param Tags
If the node values are to be supplied using the param tags, the tag names
must be as follows,
<param name="node1"
value="node value">
<param name="node2" value="node value">
<param name="node3" value="node value">
<param name="node4" value="node value">
<param name="node5" value="node value">
<param name="node6" value="node value">
etc
The applet will recognise the end of the sequence when it fails to read the next nodeN parameter. Therefore it is vital that there are no breaks within the numbering sequence. The numbering sequence should start at 1 and therefore the first node parameter should be "node1".
In a Text file
If the node parameters are to be supplied within a text file then the following
parameter must be specified,
<param name="Nodedata" value=" [ file url ] ">
where [ file url ] is the url to the file containing the node data.
If the "Nodedata" parameter is not present then the applet will assume the node data is being supplied via html PARAM's.
Comment Lines
Within the node data file comment lines may be added by beginning the line with
"<!--". Any line beginning with "<!--" will be ignored
by the tree applet.
In both methods the node
parameter comprises of the following sixteen elements,
( click on each element description for further details )
Node ID - Unique ID for this node.
Parent ID - Node ID of this node's parent.
Node Text - Text to be displayed for this node.
Font Face - Font face of this nodes text.

Expanded Flag - Specifies whether this node should be expanded on startup..
Normal Node Image - Node icon to be displayed in non-expanded state.

Mouseover Node Image - Node icon to be displayed in mouseover state.
Url - Url of the web page to display upon mouse click..
Target Frame - Frame or Window name in which to display the url upon mouse click.

For the optional parameters default values are assumed in their absence.
