 SelectMgr_AndFilter ()
 Constructs an empty selection filter object for two or more types of entity. More...
 
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. More...

Detailed Description

A framework to define a selection filter for two or more types of entity.

Constructor & Destructor Documentation

SelectMgr_AndFilter::SelectMgr_AndFilter ( )

Constructs an empty selection filter object for two or more types of entity.

Member Function Documentation

Standard_Boolean SelectMgr_AndFilter::IsOk ( const Handle< SelectMgr_EntityOwner > &  anObj) const
virtual

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.
