SelectMgr_Selection Class Reference

Represents the state of a given selection mode for a Selectable Object. Contains all the sensitive entities available for this mode. An interactive object can have an indefinite number of modes of selection, each representing a "decomposition" into sensitive primitives; each primitive has an Owner (SelectMgr_EntityOwner) which allows us to identify the exact entity which has been detected. Each Selection mode is identified by an index. The set of sensitive primitives which correspond to a given mode is stocked in a SelectMgr_Selection object. By Convention, the default selection mode which allows us to grasp the Interactive object in its entirety will be mode 0. AIS_Trihedron : 4 selection modes. More...

Constructor & Destructor Documentation

◆ SelectMgr_Selection()

SelectMgr_Selection::SelectMgr_Selection ( const Standard_Integer  theModeIdx = 0)

Constructs a selection object defined by the selection mode IdMode. The default setting 0 is the selection mode for a shape in its entirety.

◆ ~SelectMgr_Selection()

SelectMgr_Selection::~SelectMgr_Selection ( )

Member Function Documentation

◆ Add()

void SelectMgr_Selection::Add ( const Handle< SelectBasics_SensitiveEntity > &  theSensitive)

Adds the sensitive primitive to the list of stored entities in this object. Raises NullObject if the primitive is a null handle.

◆ BVHUpdateStatus()

SelectMgr_TypeOfBVHUpdate SelectMgr_Selection::BVHUpdateStatus ( ) const
inline

◆ ChangeEntities()

NCollection_Vector<Handle< SelectMgr_SensitiveEntity > >& SelectMgr_Selection::ChangeEntities ( )

("Deprecated method, Entities() should be used instead")

◆ IsEmpty()

Standard_Boolean SelectMgr_Selection::IsEmpty ( void  ) const
inline

◆ Mode()

Standard_Integer SelectMgr_Selection::Mode ( ) const
inline

returns the selection mode represented by this selection

◆ More()

Standard_Boolean SelectMgr_Selection::More ( void  ) const

Continues the iteration scanning for sensitive primitives with the mode defined in this framework.

Deprecated:
("Deprecated method, Entities() should be used instead")

◆ Next()

void SelectMgr_Selection::Next ( void  )
inline

Returns the next sensitive primitive found in the iteration. This is a scan for entities with the mode defined in this framework.

Deprecated:
("Deprecated method, Entities() should be used instead")

◆ Sensitive()

const Handle< SelectMgr_SensitiveEntity >& SelectMgr_Selection::Sensitive ( ) const
inline

Returns any sensitive primitive in this framework.

Deprecated:
("Deprecated method, Entities() should be used instead")
