Class: QgsMapToolEdit

class qgis.gui.QgsMapToolEdit

Bases: QgsMapTool

Base class for map tools that edit vector geometry

Methods

addTopologicalPoints

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

class TopologicalResult

Bases: int

addTopologicalPoints(self, vertices: Iterable[QgsPointXY]) → QgsMapToolEdit.TopologicalResult

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

addTopologicalPoints(self, vertices: Iterable[QgsPoint]) -> QgsMapToolEdit.TopologicalResult 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.

New in version 3.10.

Parameters

vertices (Iterable[QgsPointXY]) –

Return type

QgsMapToolEdit.TopologicalResult

childEvent()
connectNotify()
createGeometryRubberBand(self, geometryType: QgsWkbTypes.GeometryType = QgsWkbTypes.LineGeometry, alternativeBand: bool = False) → QgsGeometryRubberBand
Parameters
  • geometryType (QgsWkbTypes.GeometryType = QgsWkbTypes.LineGeometry) –

  • alternativeBand (bool = False) –

Return type

QgsGeometryRubberBand

createRubberBand(self, geometryType: QgsWkbTypes.GeometryType = QgsWkbTypes.LineGeometry, alternativeBand: bool = False) → QgsRubberBand

Creates a rubber band with the color/line width from the QGIS settings. The caller takes ownership of the returned object

Parameters
  • geometryType (QgsWkbTypes.GeometryType = QgsWkbTypes.LineGeometry) –

  • alternativeBand (bool = False) – if True, rubber band will be set with more transparency and a dash pattern. default is False.

Return type

QgsRubberBand

currentVectorLayer(self) → QgsVectorLayer
