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))
}
