Public Member Functions | |
StdSelect_FaceFilter (const StdSelect_TypeOfFace aTypeOfFace) | |
Constructs a face filter object defined by the type of face aTypeOfFace. | |
void | SetType (const StdSelect_TypeOfFace aNewType) |
Sets the type of face aNewType. aNewType is to be highlighted in selection. | |
StdSelect_TypeOfFace | Type () const |
Returns the type of face to be highlighted in selection. | |
virtual Standard_Boolean | IsOk (const Handle< SelectMgr_EntityOwner > &anobj) const |
Indicates that the selected Interactive Object passes the filter. The owner, anObj, can be either direct or user. A direct owner is the corresponding construction element, whereas a user is the compound shape of which the entity forms a part. When an object is detected by the mouse - in AIS, this is done through a context selector - its owner is passed to the filter as an argument. If the object returns Standard_True, it is kept; if not, it is rejected. If you are creating a filter class inheriting this framework, and the daughter class is to be used in an AIS local context, you will need to implement the virtual function ActsOn. | |
virtual Standard_Boolean | ActsOn (const TopAbs_ShapeEnum aStandardMode) const |
Returns true in an AIS local context, if this filter operates on a type of subshape defined in a filter class inheriting this framework. This function completes IsOk in an AIS local context. |
StdSelect_FaceFilter::StdSelect_FaceFilter | ( | const StdSelect_TypeOfFace | aTypeOfFace | ) |
virtual Standard_Boolean StdSelect_FaceFilter::ActsOn | ( | const TopAbs_ShapeEnum | aStandardMode | ) | const [virtual] |
Reimplemented from SelectMgr_Filter.
virtual Standard_Boolean StdSelect_FaceFilter::IsOk | ( | const Handle< SelectMgr_EntityOwner > & | anObj | ) | const [virtual] |
Implements SelectMgr_Filter.
