Detailed Description

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

The LandmarkBoxFilter element specifies a box (rectangle) filter for landmark model. Logical combinations of this and other landmark filters can be formed using LandmarkIntersectionFilter and LandmarkUnionFilter.

The following example creates a filter which filters for landmarks located within the given box (rectangle between top left and bottom right coordinates).

 PositionSource {
     id: myPositionSource
 }

 Map {
     id: map
     zoomLevel: 15
     size.width: parent.width
     size.height: parent.height
     center: myPositionSource.position.coordinate
 }

 LandmarkBoxFilter {
     id: boxFilter
     topLeft: map.toCoordinate(Qt.point(0,0))
     bottomRight: map.toCoordinate(Qt.point(map.size.width, map.size.height))
 }
