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