The QLandmarkProximityFilter class is used to search for landmarks based on the radius around a given coordinate and perform sorting by distance.
In order to be a valid filter, the region covered by the proximity filter must not cover one of the poles. The landmarks are returned in ascending order of distance. A proximity filter may be used inside an intersection filter to sort landmarks by distance in combination with other criteria such as categories. (Note that a using sort order other than QLandmarkSortOrder (i.e. no sort) will override the sorting by distance).
Creates a filter that will select landmarks within a given radius around a center coordinate.
