\qmltype GeoCircle
\instantiates QDeclarativeGeoCircle
\inqmlmodule QtLocation 5.0
\ingroup qml-QtLocation5-positioning
\since Qt Location 5.0
\brief The GeoCircle type represents a circular geographic area.
The circle is defined in terms of a \l {QtLocation5::coordinate}{coordinate} which specifies
the center of the circle and a qreal which specifies the radius of the circle in meters.
The circle is considered invalid if the center coordinate is invalid
or if the radius is less than zero.
\section2 Example Usage
The following code snippet shows the declaration of a GeoCircle object.
\code
GeoCircle {
radius: 25.0
center {
latitude: 23.34
longitude: 44.4
}
}
\endcode
This could then be used, for example, as a region to scan for landmarks,
or refining searches.
