<h2>Detailed Description</h2>
<p>The QGeoBoundingCircle class defines a circular geographic area.</p>
<p>The circle is defined in terms of a <a href="qgeocoordinate.html">QGeoCoordinate</a> which specifies the center of the circle and a qreal which specifies the radius of the circle in metres.</p>
<p>The circle is considered invalid if the center coordinate is invalid or if the radius is less than zero.</p>
