Hi Kejian,

Can you be sure that the node you've picked actually has a name? It's not
mandatory. The user (or modeller) has to set this, but if they don't the
name field will be NULL.

Or do you mean the name of a "type" of the node? (ie the name = "Geode",
"Group", etc, and this would be the same for all nodes of that type)? In
this case you can use pfGetType() or pfGetTypeName().

If you have a pointer to the Geode, pfGetParent() will give you its parent.
Bear in mind there can be multiple parents so this can be tricky. If you
need to get the specific node-path to the picked node, you could modify the
pfiPick.c routines in /usr/share/Performer/src/lib/libpfui to return this data..
