Public Member Functions | |
StdSelect_EdgeFilter (const StdSelect_TypeOfEdge Edge) | |
Constructs an edge filter object defined by the type of edge Edge. | |
void | SetType (const StdSelect_TypeOfEdge aNewType) |
Sets the type of edge aNewType. aNewType is to be highlighted in selection. | |
StdSelect_TypeOfEdge | Type () const |
Returns the type of edge 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. |
virtual Standard_Boolean StdSelect_EdgeFilter::ActsOn | ( | const TopAbs_ShapeEnum | aStandardMode | ) | const [virtual] |
Reimplemented from SelectMgr_Filter.
virtual Standard_Boolean StdSelect_EdgeFilter::IsOk | ( | const Handle< SelectMgr_EntityOwner > & | anObj | ) | const [virtual] |
Implements SelectMgr_Filter.
void StdSelect_EdgeFilter::SetType | ( | const StdSelect_TypeOfEdge | aNewType | ) |
