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 +*/ + +QDeclarativeGeoLocation::QDeclarativeGeoLocation(QObject *parent) +: QObject(parent), m_address(0) + +{ + setLocation(QGeoLocation()); +} + +QDeclarativeGeoLocation::QDeclarativeGeoLocation(const QGeoLocation &src, QObject *parent) +: QObject(parent), m_address(0) +{ + setLocation(src); +} + +QDeclarativeGeoLocation::~QDeclarativeGeoLocation() +{ +} + +/*! + \qmlproperty QGeoLocation QtPositioning::Location::location + + For details on how to use this property to interface between C++ and QML see + "\l {positioning-cpp-qml.html#location} {Interfaces between C++ and QML Code}". +*/ +void QDeclarativeGeoLocation::setLocation(const QGeoLocation &src) +{ + if (m_address && m_address->parent() == this) { + m_address->setAddress(src.address()); + } else if (!m_address || m_address->parent() != this) { + m_address = new QDeclarativeGeoAddress(src.address(), this); + emit addressChanged(); + } + + setCoordinate(src.coordinate()); + setBoundingBox(src.boundingBox()); +} + +QGeoLocation QDeclarativeGeoLocation::location() const +{ + QGeoLocation retValue; + retValue.setAddress(m_address ? m_address->address() : QGeoAddress()); + retValue.setCoordinate(m_coordinate); + retValue.setBoundingBox(m_boundingBox); + return retValue; +} + +/*! + \qmlproperty Address QtPositioning::Location::address + + This property holds the address of the location which can be use to retrieve address details of the location. +*/ +void QDeclarativeGeoLocation::setAddress(QDeclarativeGeoAddress *address) +{ + if (m_address == address) + return; + + if (m_address && m_address->parent() == this) + delete m_address; + + m_address = address; + emit addressChanged(); +} + +QDeclarativeGeoAddress *QDeclarativeGeoLocation::address() const +{ + return m_address; +} + +/*! + \qmlproperty coordinate QtPositioning::Location::coordinate + + This property holds the exact geographical coordinate of the location which can be used to retrieve the latitude, longitude and altitude of the location. + + \note this property's changed() signal is currently emitted only if the + whole object changes, not if only the contents of the object change. +*/ +void QDeclarativeGeoLocation::setCoordinate(const QGeoCoordinate coordinate) +{ + if (m_coordinate == coordinate) + return; + + m_coordinate = coordinate; + emit coordinateChanged(); +} + +QGeoCoordinate QDeclarativeGeoLocation::coordinate() const +{ + return m_coordinate; +} + +/*! + \qmlproperty georectangle QtPositioning::Location::boundingBox + + This property holds the recommended region to use when displaying the location. + For example, a building's location may have a region centered around the building, + but the region is large enough to show it's immediate surrounding geographical + context. + + Note: this property's changed() signal is currently emitted only if the + whole object changes, not if only the contents of the object change. +*/ +void QDeclarativeGeoLocation::setBoundingBox(const QGeoRectangle &boundingBox) +{ + if (m_boundingBox == boundingBox) + return; + + m_boundingBox = boundingBox; + emit boundingBoxChanged(); +} + +QGeoRectangle QDeclarativeGeoLocation::boundingBox() const +{ + return m_boundingBox; +} |
