Member Function Documentation

◆ addTopologicalPoints() [1/2]

QgsMapToolEdit::TopologicalResult QgsMapToolEdit::addTopologicalPoints ( const QVector< QgsPoint > &  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.

Since
QGIS 3.10

Definition at line 96 of file qgsmaptooledit.cpp.

◆ addTopologicalPoints() [2/2]

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.
