Detailed Description

The QContactRelationshipFilter class provides a filter based around relationship criteria.

It may be used to select contacts which are involved in relationships which are of a certain type, or which involve certain contacts.

One common use-case might be to select the contacts which are a member of a particular group. This use-case may be met with the following filter:

 QContactRelationshipFilter groupFilter;                               // select all contacts which are involved
 groupFilter.setRelationshipType(QContactRelationship::HasMember);     // in a group relationship
 groupFilter.setRelatedContact(groupContact());                   // with the group contact
 groupFilter.setRelatedContactRole(QContactRelationship::First); // where the group contact is the first participant

Another common use-case might be to select the groups which a particular contact is a member of. This use-case may be met with the following filter:

 QContactRelationshipFilter whichGroupsFilter;                                 // select all contacts which are involved
 whichGroupsFilter.setRelationshipType(QContactRelationship::HasMember); // in a group relationship
 whichGroupsFilter.setRelatedContact(particularContact());                // with the particular contact
 whichGroupsFilter.setRelatedContactRole(QContactRelationship::Second);  // where the particular contact is the second participant
