Member Enumeration Documentation

◆ SnappingMode

enum QgsSnappingConfig::SnappingMode

SnappingMode defines on which layer the snapping is performed.

Enumerator
ActiveLayer	On the active layer.
AllLayers	On all vector layers.
AdvancedConfiguration	On a per layer configuration basis.

Definition at line 45 of file qgssnappingconfig.h.

◆ SnappingType

enum QgsSnappingConfig::SnappingType

SnappingType defines on what object the snapping is performed.

Enumerator
Vertex	On vertices only.
VertexAndSegment	Both on vertices and segments.
Segment	On segments only.

Definition at line 56 of file qgssnappingconfig.h.

Constructor & Destructor Documentation

◆ QgsSnappingConfig()

QgsSnappingConfig::QgsSnappingConfig ( QgsProject * project = nullptr )

explicit

Constructor with default parameters defined in global settings.

Definition at line 100 of file qgssnappingconfig.cpp.

Member Function Documentation

◆ addLayers()

bool QgsSnappingConfig::addLayers ( const QList< QgsMapLayer *> & layers )

Adds the specified layers as individual layers to the configuration with standard configuration.

When implementing a long-living QgsSnappingConfig (like the one in QgsProject) it is best to directly feed this with information from the layer registry.

Returns: true if changes have been done.

Since: QGIS 3.0

Definition at line 369 of file qgssnappingconfig.cpp.

◆ enabled()

bool QgsSnappingConfig::enabled ( ) const

Returns if snapping is enabled.

Definition at line 162 of file qgssnappingconfig.cpp.

◆ individualLayerSettings() [1/2]

QHash< QgsVectorLayer *, QgsSnappingConfig::IndividualLayerSettings > QgsSnappingConfig::individualLayerSettings ( ) const

Returns individual snapping settings for all layers.

Definition at line 242 of file qgssnappingconfig.cpp.

◆ individualLayerSettings() [2/2]

QgsSnappingConfig::IndividualLayerSettings QgsSnappingConfig::individualLayerSettings ( QgsVectorLayer * vl ) const

Returns individual layer snappings settings (applied if mode is AdvancedConfiguration)

Definition at line 247 of file qgssnappingconfig.cpp.

◆ intersectionSnapping()
