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). |
28 | //! |
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 |
33 | //! |
34 | //! example : Selection of shapes : the owners are |
35 | //! selectable objects (presentations) |
36 | //! |
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. |
