The Curve class is used by LineString as parent class. This class could not be used directly.
From the OGC Candidate Implementation Specification: "A Curve is a 1-dimensional geometric object usually stored as a sequence of Points, with the subtype of Curve specifying the form of the interpolation between Points. This specification defines only one subclass of Curve, LineString, which uses a linear interpolation between Points."
virtual QRectF boundingBox | ( | ) | [pure virtual, inherited] |
returns the BoundingBox
The bounding box in world coordinates
Implemented in LineString, and Point.

This signal is emitted when a Geometry is clicked.
A Geometry is clickable, if the containing layer is clickable. The objects emits a signal if it gets clicked

bool isVisible | ( | ) | const [inherited] |
returns true if this Geometry is visible

QString name | ( | ) | const [inherited] |
Geometry * parentGeometry | ( | ) | const [inherited] |
returns the parent Geometry of this Geometry
A LineString is a composition of many Points. This methods returns the parent (the LineString) of a Point
QPen * pen | ( | ) | const [inherited] |
returns the QPen which is used on drawing
The pen is set depending on the Geometry. A CirclePoint for example takes one with the constructor.
void positionChanged | ( | Geometry * | geom | ) | [signal, inherited] |
void setName | ( | QString | name | ) | [inherited] |
sets the name of the geometry
name | the new name of the geometry |
void setVisible | ( | bool | visible | ) | [virtual, slot, inherited] |
if visible is true, the layer is made visible
visible | if the layer should be visible |
Reimplemented in Point.
