QGeoBoundingCircle::QGeoBoundingCircle ()
Constructs a new, invalid bounding circle.
QGeoBoundingCircle::QGeoBoundingCircle ( const QGeoCoordinate & center, qreal radius )
Constructs a new bounding circle centered at center and with a radius of radius metres.
QGeoBoundingCircle::QGeoBoundingCircle ( const QGeoBoundingCircle & other )
Constructs a new bounding circle from the contents of other.
QGeoBoundingCircle::~QGeoBoundingCircle ()
Destroys this bounding circle.
QGeoCoordinate QGeoBoundingCircle::center () const
Returns the center coordinate of this bounding circle.
See also setCenter().
bool QGeoBoundingCircle::contains ( const QGeoCoordinate & coordinate ) const [virtual]
Reimplemented from QGeoBoundingArea::contains().
Returns whether the coordinate coordinate is contained within this bounding circle.
bool QGeoBoundingCircle::isEmpty () const [virtual]
Reimplemented from QGeoBoundingArea::isEmpty().
Returns whether this bounding circle has a geometrical area of zero.
Returns true if this bounding circle is invalid.
bool QGeoBoundingCircle::isValid () const [virtual]
Reimplemented from QGeoBoundingArea::isValid().
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.
qreal QGeoBoundingCircle::radius () const
Returns the radius in meters of this bounding circle.
See also setRadius().
void QGeoBoundingCircle::setCenter ( const QGeoCoordinate & center )
Sets the center coordinate of this bounding circle to center.
See also center().
void QGeoBoundingCircle::setRadius ( qreal radius )
Sets the radius in metres of this bounding circle to radius.
See also radius().
void QGeoBoundingCircle::translate ( double degreesLatitude, double degreesLongitude )
Translates this bounding circle by degreesLatitude northwards and degreesLongitude eastwards.
Negative values of degreesLatitude and degreesLongitude correspond to southward and westward translation respectively.
QGeoBoundingCircle QGeoBoundingCircle::translated ( double degreesLatitude, double degreesLongitude ) const
Returns a copy of this bounding circle translated by degreesLatitude northwards and degreesLongitude eastwards.
Negative values of degreesLatitude and degreesLongitude correspond to southward and westward translation respectively.
See also translate().
Reimplemented from QGeoBoundingArea::type().
Returns QGeoBoundingArea::CircleType to identify this as a QGeoBoundingCircle instance.
This function is provided to help find the specific type of aQGeoBoundingArea instance.
bool QGeoBoundingCircle::operator!= ( const QGeoBoundingCircle & other ) const
Returns whether this bounding circle is not equal to other.
QGeoBoundingCircle & QGeoBoundingCircle::operator= ( const QGeoBoundingCircle & other )
Assigns other to this bounding circle and returns a reference to this bounding circle.
bool QGeoBoundingCircle::operator== ( const QGeoBoundingCircle & other ) const
Returns whether this bounding circle is equal to other.
