-- File: Select3D_SensitiveGroup.cdl -- Created: Thu Apr 16 14:57:09 1998 -- Author: Robert COUBLANC -- ---Copyright: Matra Datavision 1998 class SensitiveGroup from Select3D inherits SensitiveEntity from Select3D ---Purpose: A framework to define selection of a sensitive group -- by a sensitive entity which is a set of 3D sensitive entities. -- Remark: 2 modes are possible for rectangle selection -- the group is considered selected -- 1) when all the entities inside are selected in the rectangle -- 2) only one entity inside is selected by the rectangle -- By default the "Match All entities" mode is set. uses Pnt from gp, Projector from Select3D, Lin from gp, EntityOwner from SelectBasics, SensitiveEntity from Select3D, ListOfSensitive from Select3D, ListOfBox2d from SelectBasics, Array1OfPnt2d from TColgp, Box2d from Bnd, Location from TopLoc is Create (OwnerId : EntityOwner from SelectBasics; MatchAll : Boolean from Standard = Standard_True) returns mutable SensitiveGroup from Select3D; ---Purpose: Constructs an empty sensitive group object. -- This is a set of sensitive 3D entities. The sensitive -- entities will be defined using the function Add to fill -- the entity owner OwnerId. If MatchAll is false, nothing can be added. Create(OwnerId : EntityOwner from SelectBasics; TheList : in out ListOfSensitive from Select3D; MatchAll : Boolean from Standard = Standard_True) returns mutable SensitiveGroup from Select3D; ---Purpose: Constructs a sensitive group object defined by the list -- TheList and the entity owner OwnerId. If MatchAll is false, nothing is done. Add (me :mutable; LL: in out ListOfSensitive from Select3D); ---Purpose: Adds the list of sensitive entities LL to the empty -- sensitive group object created at construction time. Add (me :mutable;aSensitive : SensitiveEntity from Select3D); ---Purpose: Adds the sensitive entity aSensitive to the non-empty -- sensitive group object created at construction time. Remove(me:mutable; aSensitive :SensitiveEntity from Select3D); Clear(me:mutable) ; ---Purpose: Removes all sensitive entities from the list used at the -- time of construction, or added using the function Add. IsIn(me;aSensitive: SensitiveEntity from Select3D) returns Boolean from Standard; ---Purpose: Returns true if the sensitive entity aSensitive is in -- the list used at the time of construction, or added using the function Add. Set(me:mutable; MustMatchAllEntities: Boolean from Standard); ---Purpose: Sets the requirement that all sensitive entities in the -- list used at the time of construction, or added using -- the function Add must be matched. ---C++: inline MustMatchAll(me) returns Boolean from Standard; ---Purpose: Returns true if all sensitive entities in the list used -- at the time of construction, or added using the function Add must be matched. ---C++: inline Project (me:mutable;aProjector : Projector from Select3D) is redefined static; ---Level: Public ---Purpose: projection of the sensitive primitive in order to -- get 2D boxes for the Sort Algorithm Areas (me:mutable ; boxes : in out ListOfBox2d from SelectBasics) is redefined static; ---Level: Public ---Purpose: gives the 2D boxes which represent the segment in the -- selection process... MaxBoxes(me) returns Integer from Standard is redefined static; GetConnected(me:mutable;aLocation: Location from TopLoc) returns SensitiveEntity from Select3D is redefined static; SetLocation(me:mutable;aLoc:Location from TopLoc) is redefined static; ---Purpose: propagation of location on all the sensitive inside... ResetLocation(me:mutable) is redefined static; ---Purpose: propagation of location on all the sensitive inside... Matches(me :mutable; X,Y : Real from Standard; aTol: Real from Standard; DMin: out Real from Standard) returns Boolean is redefined static; ---Level: Public ---Purpose: projection of the sensitive primitive in order to -- get 2D boxes for the Sort Algorithm Matches (me :mutable; XMin,YMin,XMax,YMax : Real from Standard; aTol: Real from Standard) returns Boolean is static; Matches (me :mutable; Polyline:Array1OfPnt2d from TColgp; aBox:Box2d from Bnd; aTol: Real from Standard) returns Boolean is redefined virtual; ---Level: Public ComputeDepth(me;EyeLine: Lin from gp) returns Real from Standard is redefined static; ---Purpose: returns the depth of the touched entity SetLastPrj(me:mutable;aPrj:Projector from Select3D) is redefined virtual; Set(me:mutable;TheOwnerId: EntityOwner from SelectBasics) is redefined static; ---Purpose: Sets the owner for all entities in group GetEntities(me) returns ListOfSensitive from Select3D; ---Purpose: Gets group content ---C++: inline ---C++: return const& fields myList : ListOfSensitive from Select3D; myMustMatchAll : Boolean from Standard; myLastRank : Integer from Standard; myLastTol : ShortReal from Standard; myX,myY : ShortReal from Standard; end SensitiveGroup;
