This type is a QML representation of QGeoShape which is an abstract geographic area. It includes attributes and methods common to all geographic areas. To create objects that represent a valid geographic area use georectangle or geocircle .
The isValid attribute can be used to test if the geoshape represents a valid geographic area.
The isEmpty attribute can be used to test if the geoshape represents a region with a geometrical area of 0.
The contains () method can be used to test if a coordinate is within the geoshape.
Use properties of type
variant
to store a
geoshape
. To create a
geoshape
use one of the methods described below.
要创建
geoshape
value, specify it as a "shape()" string:
import QtPositioning Item { property variant region: "shape()" }
or with the QtPositioning.shape() 函数:
import QtPositioning 5.2 Item { property variant region: QtPositioning.shape() }
When integrating with C++, note that any
QGeoShape
value passed into QML from C++ is automatically converted into a
geoshape
value, and vice-versa.
bool isEmpty
Returns whether this geoshape is empty. An empty geoshape is a region which has a geometrical area of 0.
bool isValid
Returns whether this geoshape is valid.
A geoshape is considered to be invalid if some of the data that is required to unambiguously describe the geoshape has not been set or has been set to an unsuitable value.
ShapeType type
Returns the current type of the shape.
GeoShape.UnknownType
- The shape's type is not known.
GeoShape.RectangleType
- The shape is a
georectangle
.
GeoShape.CircleType
- The shape is a
geocircle
.
GeoShape.PathType
- The shape is a
geopath
. (Since Qt 5.9)
GeoShape.PolygonType
- The shape is a
geopolygon
. (Since Qt 5.10)
This QML property was introduced by Qt 5.5.
bool contains(coordinate coord)
返回 true 若 coordinate 指定通过 coord is within this geoshape; Otherwise returns false.
