GeometryType
The geometry types are used to group Qgis::WkbType in a coarse way.
Definition qgis.h:337
WkbType
The WKB type describes the number of dimensions a geometry has.
Definition qgis.h:256
@ LineString
LineString.
Abstract base class for all geometries.
Abstract base class for curved geometry type.
Definition qgscurve.h:35
A rubberband class for QgsAbstractGeometry (considering curved geometries).
virtual void setGeometry(QgsAbstractGeometry *geom)
Sets geometry (takes ownership). Geometry is expected to be in map coordinates.
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.
Definition qgspoint.h:49
