geoshape QML Value Type▲
-
Import Statement: import QtPositioning 6.4
-
Since:: Qt 5.2
-
Group: geoshape is part of qmlvaluetypes, qml-QtPositioning5-basictypes
Detailed Description▲
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.
Example Usage▲
Use properties of type var to store a geoshape. To create a geoshape use one of the methods described below.
To create a geoshape value, specify it as a "shape()" string:
import QtPositioning
Item {
property var region: "shape()"
}or with the QtPositioning.shape() function:
import QtPositioning
Item {
property var 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.
Properties▲
isEmpty▲
bool isEmptyReturns whether this geoshape is empty. An empty geoshape is a region which has a geometrical area of 0.
isValid▲
bool isValidReturns 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.
type▲
ShapeType typeReturns 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.
Methods▲
contains()▲
bool contains(coordinate coord)Returns true if the coordinate specified by coord is within this geoshape; Otherwise returns false.
