Actually, it's exactly the other way around -- get_path_at_pos()  
takes the click's coordinates and gives you back the path of the row  
that at that x,y position (and possibly the column and coordinates  
within the cell).  You can then ask the treeview's selection if that  
path is selected.

Warning: this code is completely untested:

     $treeview->signal_connect (button_press_event => sub {
         my ($treeview, $event) = @_;
         if ($event->button == 3   # right click
             && $event->window = $treeview->get_bin_window) {
             my $path = $treeview->get_path_at_pos ($event->x,  
$event->y);
             if ($treeview->get_selection->path_is_selected ($path)) {
                 show_my_context_menu (...);
             }
         }
         return FALSE;
     });

Now, the code there connects to button-press-event, but you can also  
connect to button-release-event, which gives you the opportunity to  
let the click change the selection before attempting to pop up the  
context menu.  Then  you don't have to pull these tricks.
