\qmltype Location
\instantiates QDeclarativeGeoLocation
\inqmlmodule QtLocation 5.0
\ingroup qml-QtLocation5-positioning
\since Qt Location 5.0
\brief The Location type holds location data.
Location types represent a geographic "location", in a human sense. This
consists of a specific \l {coordinate}, an \l {address} and a \l {boundingBox}{bounding box}.
The \l {boundingBox}{bounding box} represents the recommended region
to display when viewing this location.
The Location type is most commonly seen as the contents of a search
model such as the GeocodeModel. When a GeocodeModel returns the list of
locations found for a given query, it represents these as Location objects.
\section2 Example Usage
The following example shows a simple Location object being declared:
\code
Location {
coordinate {
latitude: -27.3
longitude: 153.1
}
address: Address {
...
}
}
\endcode
