Class: QgsMapToolCaptureLayerGeometry

Base class for map tools digitizing layer geometries.

This map tool subclass automatically handles intersection avoidance with other layers in the active project whenever a geometry is digitized by the user.

Added in version 3.26.

Base classes

QgsMapToolCapture

Base class for map tools capable of capturing point, lines and polygons.

QgsMapToolAdvancedDigitizing

A QgsMapTool which gives events directly in map coordinates and allows filtering of events.

Subclasses

QgsMapToolDigitizeFeature

This tool digitizes geometry of new point/line/polygon features on already existing vector layers.

class qgis.gui.QgsMapToolCaptureLayerGeometry[source]

Bases: QgsMapToolCapture

__init__(canvas: QgsMapCanvas | None, cadDockWidget: QgsAdvancedDigitizingDockWidget | None, mode: QgsMapToolCapture.CaptureMode)

Constructor

Parameters:
virtual layerGeometryCaptured(self, geometry: QgsGeometry)[source]

Called when the geometry is captured.

A more specific handler is also called afterwards (layerPointCaptured(), layerLineCaptured() or layerPolygonCaptured()).

Parameters:

geometry (QgsGeometry)

virtual layerLineCaptured(self, line: QgsCurve | None)[source]

Called when a line is captured.

The generic layerGeometryCaptured() method will be called immediately before this line-specific method.

Parameters:

line (Optional[QgsCurve])

virtual layerPointCaptured(self, point: QgsPoint)[source]

Called when a point is captured.

The generic layerGeometryCaptured() method will be called immediately before this point-specific method.

Parameters:

point (QgsPoint)

virtual layerPolygonCaptured(self, polygon: QgsCurvePolygon | None)[source]

Called when a polygon is captured.

The generic layerGeometryCaptured() method will be called immediately before this polygon-specific method.

Parameters:

polygon (Optional[QgsCurvePolygon])
