Selects Interactive Objects through their types. The filter questions each Interactive Object in local context to determine whether it has an non-null owner, and if so, whether it is of the desired type. If the object returns true in each case, it is kept. If not, it is rejected. By default, the interactive object has a None type and a signature of 0. A filter for type specifies a choice of type out of a range at any level enumerated for type or kind. The choice could be for kind of interactive object, of dimension, of unit, or type of axis, plane or attribute. If you want to give a particular type and signature to your Interactive Object, you must redefine two virtual methods: Type and Signature. This filter is used in both Neutral Point and open local contexts. In the Collector viewer, you can only locate Interactive Objects which answer positively to the positioned filters when a local context is open. Warning When you close a local context, all temporary interactive objects are deleted, all selection modes concerning the context are cancelled, and all content filters are emptied. More...

AIS_TypeFilter (const AIS_KindOfInteractive aGivenKind) | |
Initializes filter for type, aGivenKind. More... | |
virtual Standard_Boolean | IsOk (const Handle< SelectMgr_EntityOwner > &anobj) const |

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. More... | |

virtual |
Returns False if the transient is not an Interactive Object, or if the type of the Interactive Object is not the same as that stored in the filter.
