# geocircle QML Basic Type

The geocircle type represents a circular geographic area.

The `geocircle` type is a geoshape that represents a circular geographic area. It is a direct representation of a QGeoCircle and is defined in terms of a 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.

## Example Usage

Use properties of type variant to store a `geocircle`. To create a `geocircle` value, use the QtPositioning.circle() function:

      import QtPositioning 5.2

      Item {
          property variant region: QtPositioning.circle(QtPositioning.coordinate(-27.5, 153.1), 1000)
      }

When integrating with C++, note that any QGeoCircle value passed into QML from C++ is automatically converted into a `geocircle` value, and vise-versa.

## Properties

### center

      coordinate radius

This property holds the coordinate of the center of the geocircle.

### radius

      real radius

This property holds the radius of the geocircle in meters.

The default value for the radius is -1 indicating an invalid geocircle area.
