Typedef Documentation

QgsMultiPointXY

typedef QVector<QgsPointXY> QgsMultiPointXY

A collection of QgsPoints that share a common collection of attributes.

Definition at line 96 of file qgsgeometry.h.

QgsMultiPolygonXY

typedef QVector<QgsPolygonXY> QgsMultiPolygonXY

A collection of QgsPolygons that share a common collection of attributes.

Definition at line 107 of file qgsgeometry.h.

QgsMultiPolyline

typedef QVector<QgsPolyline> QgsMultiPolyline

Multi polyline represented as a vector of polylines.

This type has full support for Z/M dimensions.

Since

QGIS 3.44

Definition at line 83 of file qgsgeometry.h.

QgsMultiPolylineXY

typedef QVector<QgsPolylineXY> QgsMultiPolylineXY

A collection of QgsPolylines that share a common collection of attributes.

Definition at line 100 of file qgsgeometry.h.

QgsPolygonXY

typedef QVector<QgsPolylineXY> QgsPolygonXY

Polygon: first item of the list is outer ring, inner rings (if any) start from second item.

Definition at line 90 of file qgsgeometry.h.

QgsPolyline

typedef QgsPointSequence QgsPolyline

Polyline as represented as a vector of points.

This type has full support for Z/M dimensions.

Definition at line 70 of file qgsgeometry.h.

QgsPolylineXY

typedef QVector<QgsPointXY> QgsPolylineXY

Polyline as represented as a vector of two-dimensional points.

This type has no support for Z/M dimensions and use of QgsPolyline is encouraged instead.

Note

In QGIS 2.x this type was available as QgsPolyline.

Definition at line 61 of file qgsgeometry.h.
