◆ addFeatureV2()

bool QgsTrackedVectorLayerTools::addFeatureV2 ( QgsVectorLayer layer,
const QgsAttributeMap defaultValues,
const QgsGeometry defaultGeometry,
QgsFeature feature,
const QgsVectorLayerToolsContext context 
) const
overridevirtual

This method calls the addFeature method of the backend QgsVectorLayerTools.

Parameters
layerThe layer to which the feature should be added
defaultValuesDefault values for the feature to add
defaultGeometryA default geometry to add to the feature
featureA pointer to the feature
contextA context object to be used for e.g. to calculate feature expression-based values (since QGIS 3.38)
Returns
true in case of success, false if the operation failed/was aborted

Reimplemented from QgsVectorLayerTools.

Definition at line 22 of file qgstrackedvectorlayertools.cpp.

◆ copyMoveFeatures()

bool QgsTrackedVectorLayerTools::copyMoveFeatures ( QgsVectorLayer layer,
QgsFeatureRequest request,
double  dx = 0,
double  dy = 0,
QString *  errorMsg = nullptr,
const bool  topologicalEditing = false,
QgsVectorLayer topologicalLayer = nullptr,
QString *  childrenInfoMsg = nullptr 
) const
overridevirtual

Copy and move features with defined translation.

Parameters
layerThe layer
requestThe request for the features to be moved. It will be assigned to a new feature request with the newly copied features.
dxThe translation on x
dyThe translation on y
errorMsgIf given, it will contain the error message
topologicalEditingIf true, the function will perform topological editing of the vertices of layer on layer and topologicalLayer
topologicalLayerThe layer where vertices from the moved features of layer will be added
childrenInfoMsgIf given, it will contain messages related to the creation of child features
Returns
true if all features could be copied.

Reimplemented from QgsVectorLayerTools.

Definition at line 59 of file qgstrackedvectorlayertools.cpp.

◆ rollback()

void QgsTrackedVectorLayerTools::rollback ( )

Delete all features which have been added via this object.

Definition at line 69 of file qgstrackedvectorlayertools.cpp.

◆ saveEdits()

bool QgsTrackedVectorLayerTools::saveEdits ( QgsVectorLayer layer) const
overridevirtual

Should be called, when the features should be committed but the editing session is not ended.

Parameters
layerThe layer to commit
Returns
true if successful

Implements QgsVectorLayerTools.

Definition at line 54 of file qgstrackedvectorlayertools.cpp.

◆ setVectorLayerTools()

void QgsTrackedVectorLayerTools::setVectorLayerTools ( const QgsVectorLayerTools tools)

Set the vector layer tools that will be used to interact with the data.

Definition at line 64 of file qgstrackedvectorlayertools.cpp.

◆ startEditing()

bool QgsTrackedVectorLayerTools::startEditing ( QgsVectorLayer layer) const
overridevirtual

This will be called, whenever a vector layer should be switched to edit mode.

Check the providers capability to edit in here. If successful layer->startEditing() will be called and true returned.

Parameters
layerThe layer on which to start an edit session
Returns
true, if the editing session was started

Implements QgsVectorLayerTools.

Definition at line 44 of file qgstrackedvectorlayertools.cpp.

◆ stopEditing()

bool QgsTrackedVectorLayerTools::stopEditing ( QgsVectorLayer layer,
bool  allowCancel 
) const
overridevirtual

Will be called, when an editing session is ended and the features should be committed.

Appropriate dialogs should be shown like

Parameters
layerThe layer to commit
allowCanceltrue if a cancel button should be offered
Returns
true if successful

Implements QgsVectorLayerTools.
