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.

This function was introduced in Qt Mobility 1.1.

QGeoBoundingCircle::QGeoBoundingCircle ( const QGeoBoundingCircle & other )

Constructs a new bounding circle from the contents of other.

This function was introduced in Qt Mobility 1.1.

QGeoBoundingCircle::~QGeoBoundingCircle ()

Destroys this bounding circle.

QGeoCoordinate QGeoBoundingCircle::center () const

Returns the center coordinate of this bounding circle.

This function was introduced in Qt Mobility 1.1.

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.

This function was introduced in Qt Mobility 1.1.

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.

This function was introduced in Qt Mobility 1.1.

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.

This function was introduced in Qt Mobility 1.1.

qreal QGeoBoundingCircle::radius () const

Returns the radius in meters of this bounding circle.

This function was introduced in Qt Mobility 1.1.

See also setRadius().

void QGeoBoundingCircle::setCenter ( const QGeoCoordinate & center )

Sets the center coordinate of this bounding circle to center.

This function was introduced in Qt Mobility 1.1.

See also center().

void QGeoBoundingCircle::setRadius ( qreal radius )

Sets the radius in meters of this bounding circle to radius.

This function was introduced in Qt Mobility 1.1.

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.

This function was introduced in Qt Mobility 1.1.

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.

This function was introduced in Qt Mobility 1.1.

See also translate().

QGeoBoundingArea::AreaType QGeoBoundingCircle::type () const [virtual]

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.

This function was introduced in Qt Mobility 1.1.

bool QGeoBoundingCircle::operator!= ( const QGeoBoundingCircle & other ) const

Returns whether this bounding circle is not equal to other.

This function was introduced in Qt Mobility 1.1.

QGeoBoundingCircle & QGeoBoundingCircle::operator= ( const QGeoBoundingCircle & other )

Assigns other to this bounding circle and returns a reference to this bounding circle.

This function was introduced in Qt Mobility 1.1.

bool QGeoBoundingCircle::operator== ( const QGeoBoundingCircle & other ) const

Returns whether this bounding circle is equal to other.

This function was introduced in Qt Mobility 1.1.
