Member Function Documentation

◆ addTopologicalPoints() [1/2]

QgsMapToolEdit::TopologicalResult QgsMapToolEdit::addTopologicalPoints ( const QVector< QgsPointXY > & vertices )

protected

Adds a list of vertices to other features to keep topology up to date, e.g.

to neighbouring polygons. The vertices list specifies a set of topological points to add, in the layer's coordinate reference system.

Deprecated:: since QGIS 3.12 - will be removed in QGIS 4.0. Use the variant which accepts QgsPoint objects instead of QgsPointXY.

Definition at line 118 of file qgsmaptooledit.cpp.

◆ addTopologicalPoints() [2/2]

QgsMapToolEdit::TopologicalResult QgsMapToolEdit::addTopologicalPoints ( const QVector< QgsPoint > & vertices )

Adds a list of vertices to other features to keep topology up to date, e.g.

to neighbouring polygons. The vertices list specifies a set of topological points to add, in the layer's coordinate reference system.

Since: QGIS 3.10
