- Public Member Functions inherited from Select3D_SensitiveEntity
virtual Handle< Select3D_SensitiveEntityGetConnected ()
 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. More...
