17 | deferred class EntityOwner from SelectBasics inherits TShared from MMgt |
18 | |
19 | ---Purpose: defines an abstract owner of sensitive primitives. |
20 | -- Owners are typically used to establish a connection |
21 | -- between sensitive entities and high-level objects (e.g. presentations). |
22 | -- |
23 | -- Priority : It's possible to give a priority: |
24 | -- the scale : [0-9] ; the default priority is 0 |
25 | -- it allows the predominance of one selected object upon |
26 | -- another one if many objects are selected at the same time |
27 | -- |
28 | -- |
29 | -- example : Selection of shapes : the owners are |
30 | -- selectable objects (presentations) |
31 | -- |
32 | -- a user can give vertex priority [3], edges [2] faces [1] shape [0], |
33 | -- so that if during selection one vertex one edge and one face are |
34 | -- simultaneously detected, the vertex will only be hilighted. |
