25 //! defines an abstract owner of sensitive primitives.
26 //! Owners are typically used to establish a connection
27 //! between sensitive entities and high-level objects (e.g. presentations).
29 //! Priority : It's possible to give a priority:
30 //! the scale : [0-9] ; the default priority is 0
31 //! it allows the predominance of one selected object upon
32 //! another one if many objects are selected at the same time
34 //! example : Selection of shapes : the owners are
35 //! selectable objects (presentations)
37 //! a user can give vertex priority [3], edges [2] faces [1] shape [0],
38 //! so that if during selection one vertex one edge and one face are
39 //! simultaneously detected, the vertex will only be hilighted.
