Detailed Description

A framework to define sensitive zones along a segment One gives the 3D start and end point.

Constructor & Destructor Documentation

Select3D_SensitiveSegment::Select3D_SensitiveSegment ( const Handle< SelectBasics_EntityOwner > &  theOwnerId,
const gp_Pnt theFirstPnt,
const gp_Pnt theLastPnt 
)

Constructs the sensitive segment object defined by the owner theOwnerId, the points theFirstPnt, theLastPnt.

Member Function Documentation

virtual Select3D_BndBox3d Select3D_SensitiveSegment::BoundingBox ( )
overridevirtual

Returns bounding box of the segment. If location transformation is set, it will be applied.

Implements Select3D_SensitiveEntity.

virtual gp_Pnt Select3D_SensitiveSegment::CenterOfGeometry ( ) const
overridevirtual

Returns center of the segment. If location transformation is set, it will be applied.

Implements Select3D_SensitiveEntity.

void Select3D_SensitiveSegment::EndPoint ( const gp_Pnt thePnt)

changes the end point of the segment

gp_Pnt Select3D_SensitiveSegment::EndPoint ( ) const

gives the 3D End Point of the Segment

virtual Handle< Select3D_SensitiveEntity > Select3D_SensitiveSegment::GetConnected ( )
overridevirtual

Originally this method intended to return sensitive entity with new location aLocation, but currently sensitive entities do not hold a location, instead HasLocation() and Location() methods call corresponding entity owner's methods. Thus all entities returned by GetConnected() share the same location propagated from corresponding selectable object. You must redefine this function for any type of sensitive entity which can accept another connected sensitive entity.//can be connected to another sensitive entity.

Reimplemented from Select3D_SensitiveEntity.

virtual Standard_Boolean Select3D_SensitiveSegment::Matches ( SelectBasics_SelectingVolumeManager theMgr,
SelectBasics_PickResult thePickResult 
)
overridevirtual

Checks whether the segment overlaps current selecting volume.

Reimplemented from Select3D_SensitiveEntity.

virtual Standard_Integer Select3D_SensitiveSegment::NbSubElements ( )
overridevirtual

Returns the amount of points.

Implements Select3D_SensitiveEntity.

void Select3D_SensitiveSegment::StartPoint ( const gp_Pnt thePnt)

changes the start Point of the Segment;

gp_Pnt Select3D_SensitiveSegment::StartPoint ( ) const

gives the 3D start Point of the Segment
