UI Panel: Get notified when Playlist Tree gets selected

Is there a way of being notified if the Playlist Tree's node is active or selected?

Basically, in UI Panels, I want to get notified whenever one of the Playlist Tree's nodes get selected.

This shouldn't be confuse with UI Panel's "%playlistname%" or CBW Hooks's "%cwb_activelist%", whom both return the active playlist's name, which is not what im looking for.

Im looking for a way to know if/when a node itself is active, not the node's playlist. Or even better, the selected/active node's index, where "-1" or "null" is returned if none of the nodes are active/selected.
Something like %playlist_tree_selected_node%

Here is a link to Bowron's Playlist Tree page:
Playlist Tree

When you go to the link above, and scroll down to the " For Developers" section, you will see that his plugin can notify other pulgins when his Playlist Tree's nodes get selected, here is his piece of code for reference.

Code: [Select]
class callback_node
{
public:
   virtual bool   get_entries( pfc::list_base_t<metadb_handle_ptr> & list ) const = 0;
   virtual bool   is_leaf() const     = 0;
   virtual bool   is_folder() const   = 0;
   virtual bool   is_query() const    = 0;
   virtual int    get_entry_count() const = 0;
   virtual void   get_name( pfc::string_base & out ) const = 0; 
};

class NOVTABLE node_select_callback : public service_base 
{
public:
   virtual void on_node_select( const callback_node * node ) = 0;

   FB2K_MAKE_SERVICE_INTERFACE_ENTRYPOINT(node_select_callback);
};

const GUID node_select_callback::class_guid = 
{ 0x9c2ae3c3, 0xdc04, 0x4042, { 0xad, 0xf3, 0x88, 0x84, 0x11, 0x7b, 0x49, 0x55 } };


Is there a component that can do this? that is, get the selected node's index?
I really need some help on this one, please help, someone, anyone. 

Thanks in advanced.

Anyone looking at this? I'd find it really useful too.

(Generally, I find that getting plug-ins to work together is difficult if not next-to-impossible in Foobar - it's its biggest weakness as far as I'm concerned).
