This class is the base class for classes which specify a geographic area.
For the sake of consistency, subclasses should describe the specific details of the associated areas in terms of QGeoCoordinate instances and distances in meters.
This class is a Q_GADGET since Qt 5.5. It can be directly used from C++ and QML.
Describes the type of the shape.
Constant | Value | Description |
---|---|---|
QGeoShape::UnknownType |
0 |
A shape of unknown type |
QGeoShape::RectangleType |
1 |
A rectangular shape |
QGeoShape::CircleType |
2 |
A circular shape |
QGeoShape::PathType |
3 |

isEmpty : const boolThis property defines whether this geo shape is empty.
An empty geo shape is a region which has a geometrical area of 0.
While this property is introduced in Qt 5.5, the related accessor functions exist since the first version of this class.
This property was introduced in Qt 5.5.
Access functions:
bool | isEmpty() const |
[read-only, since 5.5]
isValid : const boolThis property holds the validity of the geo shape.
A geo shape is considered to be invalid if some of the data that is required to unambiguously describe the geo shape has not been set or has been set to an unsuitable value depending on the subclass of this object. The default constructed objects of this type are invalid.
While this property is introduced in Qt 5.5, the related accessor functions exist since the first version of this class.
This property was introduced in Qt 5.5.

This property was introduced in Qt 5.5.
Access functions:
QGeoShape::ShapeType | type() const |
Constructs a new geo shape which is a copy of other.
Constructs a new invalid geo shape of UnknownType.
Assigns other to this geo shape and returns a reference to this geo shape.
Destroys this geo shape.
[invokable, since 5.9]
QGeoRectangle QGeoShape::boundingGeoRectangle() constReturns a QGeoRectangle representing the geographical bounding rectangle of the geo shape, that defines the latitudinal/longitudinal bounds of the geo shape.
Note: This function can be invoked via the meta-object system and from QML. See Q_INVOKABLE.
This function was introduced in Qt 5.9.
[since 5.5]
QGeoCoordinate QGeoShape::center() constReturns the coordinate located at the geometric center of the geo shape.
Note: Getter function for property center.
This function was introduced in Qt 5.5.
[invokable]
bool QGeoShape::contains(const QGeoCoordinate
&coordinate) constReturns whether the coordinate coordinate is contained within this geo shape.
Note: This function can be invoked via the meta-object system and from QML. See Q_INVOKABLE.
Returns whether this geo shape is empty.
An empty geo shape is a region which has a geometrical area of 0.
Note: Getter function for property isEmpty.
Returns whether this geo shape is valid.
Note: Getter function for property isValid.
[invokable, since 5.5]
QString QGeoShape::toString() constReturns a string representation of this geo shape.
Note: This function can be invoked via the meta-object system and from QML. See Q_INVOKABLE.
This function was introduced in Qt 5.5.
Returns the type of this geo shape.
Note: Getter function for property type.
Returns the hash value for the shape, using seed for the calculation.
Returns true
if the lhs geo shape is not equivalent to the rhs geo shape, otherwise returns false
.
Returns true
if the lhs geo shape is equivalent to the rhs geo shape, otherwise returns false
