QGeoBoundingCircle
Since: 1.1
#include <QtLocationSubset/QGeoBoundingCircle>
The QGeoBoundingCircle class defines a circular geographic area.
The circle is defined in terms of a QGeoCoordinate which specifies the center of the circle and a qreal which specifies the radius of the circle in metres.
The circle is considered invalid if the center coordinate is invalid or if the radius is less than zero.

Public Functions
Constructs a new, invalid bounding circle.
Constructs a new bounding circle centered at center and with a radius of radius metres.
Constructs a new bounding circle from the contents of other.
Destructor.
QGeoCoordinate
Returns the center coordinate of this bounding circle.
virtual bool
Returns whether the coordinate coordinate is contained within this bounding circle.
virtual bool
Returns whether this bounding circle has a geometrical area of zero.
Returns true if this bounding circle is invalid.
virtual bool
Returns whether this bounding circle is valid.
A valid bounding circle has a valid center coordinate and a radius greater than or equal to zero.
bool
Returns whether this bounding circle is not equal to other.
QGeoBoundingCircle &
Assigns other to this bounding circle and returns a reference to this bounding circle.
bool
Returns whether this bounding circle is equal to other.
qreal
Returns the radius in meters of this bounding circle.
void
Sets the center coordinate of this bounding circle to center.
void
Sets the radius in meters of this bounding circle to radius.
void
Translates this bounding circle by degreesLatitude northwards and degreesLongitude eastwards.
Negative values of degreesLatitude and degreesLongitude correspond to southward and westward translation respectively.
QGeoBoundingCircle
Returns a copy of this bounding circle translated by degreesLatitude northwards and degreesLongitude eastwards.
virtualQGeoBoundingArea::AreaType
Returns QGeoBoundingArea::CircleType to identify this as a QGeoBoundingCircle instance.
This function is provided to help find the specific type of aQGeoBoundingArea instance.
