SelectMgr_AndFilter () | |
Constructs an empty selection filter object for two or more types of entity. | |
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. |
Standard_Boolean SelectMgr_AndFilter::IsOk | ( | const Handle< SelectMgr_EntityOwner > & | anObj | ) | const [virtual] |
Implements SelectMgr_Filter.
