BoundingCircleThe BoundingCircle element represents a circular geographic area. More... Inherits QtObject This type was introduced in Qt Location 5.0. PropertiesDetailed DescriptionThe circle 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 UsageThe following code snippet shows the declaration of a BoundingCircle element. BoundingCircle {
radius: 25.0
center: Coordinate {
latitude: 23.34
longitude: 44.4
}
}
This could then be used, for example, as a region to scan for landmarks, or refining searches. See also QGeoBoundingCircle. Property DocumentationThis property holds the coordinate of the center of the bounding circle. Note: this property's changed() signal is currently emitted only if the whole element changes, not if only the contents of the element change. For details on how to use this property to interface between C++ and QML see "Interfaces between C++ and QML Code". This property holds the radius of the bounding circle in meters. The default value for the radius is -1 indicating an invalid bounding circle area. |
