\since Qt Location 5.0
\brief A geoshape type represents an abstract geographic area.
The \c geoshape type represents an abstract geographic area. It includes attributes and
methods common to all geographic areas. To create objects that represent a valid geographic
area use \l {QtLocation5::georectangle}{georectangle} or
\l {QtLocation5::geocircle}{geocircle}.
The \c isValid attribute can be used to test if the geoshape represents a valid geographic
area.
The \c isEmpty attribute can be used to test if the geoshape represents a region with a
geomatrical area of 0.
The \l contains() method can be used to test if a \l {QtLocation5::coordinate}{coordinate} is
within the geoshape.
\section2 Example Usage
Use properties of type \l variant to store a \c {geoshape}. To create a \c geoshape use one
of the methods described below.
To create a \c geoshape value, specify it as a "shape()" string:
\qml
import QtLocation
Item {
property variant region: "shape()"
}
\endqml
or with the \l {QtLocation5::QtLocation}{QtLocation.shape()} function:
\qml
import QtLocation 5.0
Item {
property variant region: QtLocation.shape()
}
\endqml
When integrating with C++, note that any QGeoShape value passed into QML from C++ is
automatically converted into a \c geoshape value, and vice-versa.
\section2 Methods
\section3 contains()
\code
bool contains(coordinate coord)
\endcode
Returns true if the \l {QtLocation5::coordinate}{coordinate} specified by \a coord is within
this geoshape; Otherwise returns false.
