GeometryType
The geometry types are used to group Qgis::WkbType in a coarse way.
WkbType
The WKB type describes the number of dimensions a geometry has.
@ CircularString
CircularString.
Abstract base class for all geometries.
Circular string geometry type.
Compound curve geometry type.
Curve polygon geometry type.
Abstract base class for curved geometry type.
A rubberband class for QgsAbstractGeometry (considering curved geometries).
void setGeometryType(Qgis::GeometryType geometryType)
Sets which geometry is handled by the rubber band, polygon or line.
virtual void setGeometry(QgsAbstractGeometry *geom)
Sets geometry (takes ownership). Geometry is expected to be in map coordinates.
Line string geometry type, with support for z-dimension and m-values.
Map canvas is a class for displaying all GIS data types on a canvas.
Point geometry type, with support for z-dimension and m-values.
