Open CASCADE Technology 6.6.0
|
A framework to supply the structure of the object to be
selected. At the first pick, this structure is created by
calling the appropriate algorithm and retaining this
framework for further picking.
This abstract framework is inherited in Application
Interactive Services (AIS), notably in AIS_InteractiveObject.
Consequently, 3D selection should be handled by the
relevant daughter classes and their member functions
in AIS. This is particularly true in the creation of new interactive objects.

Public Member Functions | |
virtual Standard_Integer | NbPossibleSelection () const |
defines the number of different modes of selection (or decomposition) for an Object. | |
void | UpdateSelection () |
re-computes the sensitive primitives for all modes | |
void | UpdateSelection (const Standard_Integer aMode) |
re-computes the sensitive primitives which correspond to the <amode>th selection mode. | |
void | AddSelection (const Handle< SelectMgr_Selection > &aSelection, const Standard_Integer aMode) |
Adds the selection aSelection with the selection mode index aMode to this framework. | |
void | ClearSelections (const Standard_Boolean update=Standard_False) |
Empties all the selections in the SelectableObject <update> parameter defines whether all object's selections should be flagged for further update or not. This improved method can be used to recompute an object's selection (without redisplaying the object completely) when some selection mode is activated not for the first time. | |
const Handle_SelectMgr_Selection & | Selection (const Standard_Integer aMode) const |
Returns the selection Selection having the selection mode aMode. | |
Standard_Boolean | HasSelection (const Standard_Integer aMode) const |
Returns true if a selection corresponding to the selection mode aMode is present in this framework. | |
void | Init () |
Begins the iteration scanning for sensitive primitives. | |
Standard_Boolean | More () const |
Continues the iteration scanning for sensitive primitives. | |
void | Next () |
Continues the iteration scanning for sensitive primitives. | |
const Handle_SelectMgr_Selection & | CurrentSelection () const |
Returns the current selection in this framework. | |
void | ResetLocation () |
virtual void | UpdateLocation () |
Recomputes the location of the selection aSelection. | |
virtual void | HilightSelected (const Handle< PrsMgr_PresentationManager3d > &PM, const SelectMgr_SequenceOfOwner &Seq) |
Method which draws selected owners ( for fast presentation draw ) | |
virtual void | ClearSelected () |
Method which clear all selected owners belonging to this selectable object ( for fast presentation draw ) | |
virtual void | HilightOwnerWithColor (const Handle< PrsMgr_PresentationManager3d > &thePM, const Quantity_NameOfColor theColor, const Handle< SelectMgr_EntityOwner > &theOwner) |
Method which hilight an owner belonging to this selectable object ( for fast presentation draw ) | |
virtual Standard_Boolean | IsAutoHilight () const |
If returns True, the old mechanism for highlighting selected objects is used (HilightSelected Method may be empty). If returns False, the HilightSelected method will be fully responsible for highlighting selected entity owners belonging to this selectable object. | |
virtual void | SetAutoHilight (const Standard_Boolean newAutoHilight) |
Set AutoHilight property to true or false //! Sets up Transform Persistence Mode for this object | |
Handle_Prs3d_Presentation | GetHilightPresentation (const Handle< PrsMgr_PresentationManager3d > &TheMgr) |
Handle_Prs3d_Presentation | GetSelectPresentation (const Handle< PrsMgr_PresentationManager3d > &TheMgr) |
virtual void | SetZLayer (const Handle< PrsMgr_PresentationManager > &thePrsMgr, const Standard_Integer theLayerId) |
Set Z layer ID and update all presentations of the selectable object. The layer can be set only for displayed object. If all object presentations are removed, the layer ID will be set to default value when computing presentation. The layers mechanism allows drawing objects in higher layers in overlay of objects in lower layers. | |
