Blt_TreeNodeId - Returns the node serial number.
- Blt_TreeNode node (in)
- Node whose ID is to be returned.
This procedure returns the node serial number. The node serial number is useful
for programs that export the tree data object to the Tcl programming level.
Since node labels (and therefore pathnames) are not unique, the ID can be used
to uniquely identify a node.
The arguments are as follows:
- The node whose serial number is returned. The serial number
of the root node for example is always 0.
The serial number of the node. Nodes are given a unique serial number when they
are created. You can use the ID to later retrieve the node using
The following example prints the ID of a node.
printf("root ID is %s\n", Blt_TreeNodeId(node));
