QGeoBoundingArea ClassThe QGeoBoundingArea class defines a geographic area. More... #include <QGeoBoundingArea>Inherited by: QGeoBoundingBox and QGeoBoundingCircle. This class was introduced in Qt Location 5.0. Public Types
Public Functions
Detailed DescriptionThe QGeoBoundingArea class defines a geographic area. This class is the base class for classes which specify a geographic area. For the sake of consistency, subclasses should describe the specific details of the associated areas in terms of QGeoCoordinate instances and distances in meters. Member Type Documentation

Member Function Documentation
QGeoBoundingArea::QGeoBoundingArea()
Constructs a new invalid bounding area of UnknownType.
QGeoBoundingArea::QGeoBoundingArea(const QGeoBoundingArea & other)
Constructs a new bounding area which is a copy of other.
QGeoBoundingArea::~QGeoBoundingArea()
Destroys this bounding area.
bool QGeoBoundingArea::contains(const QGeoCoordinate & coordinate) const
Returns whether the coordinate coordinate is contained within this area.
bool QGeoBoundingArea::isEmpty() const
Returns whether this bounding area is empty.
An empty area is a region which has a geometrical area of 0.
bool QGeoBoundingArea::isValid() const
Returns whether this bounding area is valid.
An area is considered to be invalid if some of the data that is required to unambiguously describe the area has not been set or has been set to an unsuitable value.
AreaType QGeoBoundingArea::type() const
Returns the type of this area.
bool QGeoBoundingArea::operator!=(const QGeoBoundingArea & other) const
Returns true if the other bounding area is not equivalent to this bounding area, otherwise returns false.
QGeoBoundingArea & QGeoBoundingArea::operator=(const QGeoBoundingArea & other)
Assigns other to this bounding area and returns a reference to this bounding area.
bool QGeoBoundingArea::operator==(const QGeoBoundingArea & other) const
Returns true if the other bounding area is equivalent to this bounding area, otherwise returns false
