Detailed Description

The LandmarkProximityFilter element specifies a proximity filter for landmark model. Logical combinations of this and other landmark filters can be formed using LandmarkIntersectionFilter and LandmarkUnionFilter.

This element is part of the QtMobility.location 1.1 module.

The following example creates a filter which filters for landmarks located within 1500 metres of the current position.

 PositionSource {
     id: myPosition
     updateInterval: 1000
 }
 LandmarkProximityFilter {
     id: landmarkFilterMyCurrentLocation
     center: myPosition.position.coordinate
     radius: 1500
 }
