17 deferred class EntityOwner from SelectBasics inherits TShared from MMgt
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).
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
29 -- example : Selection of shapes : the owners are
30 -- selectable objects (presentations)
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.
42 Initialize (aPriority: Integer = 0) ;
45 Set (me:mutable; aPriority :Integer) is static;
47 ---Purpose: sets the selectable priority of the owner
50 Priority(me) returns Integer is static;
54 -- Deferred methods dealing with locations.
55 -- Used in Select3D package.
56 HasLocation(me) returns Boolean from Standard is deferred;
58 SetLocation(me:mutable; aLoc : Location from TopLoc) is deferred;
60 ResetLocation(me:mutable) is deferred;
62 Location(me) returns Location from TopLoc is deferred;
69 mypriority : Integer is protected;
