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.
Constructs a new, invalid bounding circle.
Constructs a new bounding circle centered at center and with a radius of radius metres.
This function was introduced in Qt Mobility 1.1.
Constructs a new bounding circle from the contents of other.
This function was introduced in Qt Mobility 1.1.
Destroys this bounding circle.
Returns the center coordinate of this bounding circle.
This function was introduced in Qt Mobility 1.1.
See also setCenter().
Reimplemented from QGeoBoundingArea::contains().
Returns whether the coordinate coordinate is contained within this bounding circle.
This function was introduced in Qt Mobility 1.1.
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.
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.
Returns the radius in meters of this bounding circle.
This function was introduced in Qt Mobility 1.1.
See also setRadius().
Sets the center coordinate of this bounding circle to center.
This function was introduced in Qt Mobility 1.1.
See also center().
Sets the radius in meters of this bounding circle to radius.
This function was introduced in Qt Mobility 1.1.
See also radius().
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.
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().
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.
Returns whether this bounding circle is not equal to other.
This function was introduced in Qt Mobility 1.1.
Assigns other to this bounding circle and returns a reference to this bounding circle.
This function was introduced in Qt Mobility 1.1.
Returns whether this bounding circle is equal to other.
